You Answered my question concerning that blanket box. I truly thank God for the heart that you have. I stumbled upon your videos two weeks ago and all of my questions were answered. I hope you remain healthy and financially successful for all that you do for us. Blessings and peace to you and your family, Anderson McCant, Atlanta, Ga.
Guy at discount auto was very knowledgeable and told me to avoid The Dorman Manifold and hearing this only makes me feel even more confident in avoiding this.. thanks so much for your time and knowledge brother.. really appreciate the tips bud!!🤜🏻🤛🏻
Thank you Ron, this video answered exactly what I wanted to know. I was going for the Dorman on a recommendation from another post.I'm just glad I caught your video first. I wished you had a shop in southern AZ. You would have a life long customer. You'r experience and honesty are hard to find these days. Your website is in my favorites for good. Thank you again.
I have a 2000 expedition 5.4, I used the doorman, a year later it started leaking. Took it off and the gaskets were very flat and allowing coolant to seep through, I went to autozone and bought better quality ones.(you might want to replace them preventatively before installation, they were pretty cheap), has been fine for over 2 years now. As for the self tapping screws, I screwed them in first while off the motor, that way when I screwed them later they went in easy and straight. The one problem I did have was that where the fuel rail mounts to the intake, the intake is at a slight inward angle, where the motorcraft one is perfectly vertical, therefore when the rail was tightened it pulled the rail off center of the injector tops and therefore created leaks in almost all the injectors. I made spacers to put between the intake and the fuel rail using old spacers from injector tips and some washers I had. That aligned the rail with the top of the injectors and solved the issue. While you have all that out change your plugs, clean the mass airflow sensor, egr, iac, throttle body and replace the pcv valve, you'll be impressed by how strong and smooth your old 5.4 will run afterwards.
@@SandCarServices no, you pull out the existing ones, they are rubber and not glued in or anything like that. You simply pull them out and push in the new ones. Its exactly like replacing the ones on the cross over pipe they are simply wedged in there.
On your expedition did you use this part number from Dorman or was it a slightly different model? Also did you rebuild the injectors or just put them back in as is. I am working on a 1998 5.4 expedition, have manifold(s) , coils, and injectors off and new spark plugs and coils to replace (got a lot of cleaning to do lol)
@@charlesbowers3420 I don't remember the part number (used whatever came up for a 2000 5.4) I used the injector rebuild kit which was simply new hats and o rings. I also cleaned them using methods I found on UA-cam with a 9 volt battery, brake cleaner and some hose. Even though it ran fine before, the injectors were pretty dirty and sputtered instead of spraying, before the cleaning. Ran great when all put back together. Good luck with yours. By the way, I have had no problems since. It's plastic so make sure to use a torque wrench.
Thank you sir, I was struggling to find if I needed a gasket with the seals, and I was trying to find out how to snap that box onto the new Dorman! But you covered it in the video! Thanks again!
Hi Ron I am one of your subscribers, I have a 2003 F-150 your videos have been very helpful to me as I attempt to make repairs on my truck. Here is what is going on: I just finished replacing the intake manifold yesterday on my 2003 5.4L F-150 with the Dorman, after the replacement the engine started up right away, therefore putting a smile on my face. Unfortunately, that did not last too long, I turned the truck around in my driveway and the engine started to bog down, parked the truck opened the hood to find no obvious problem. No immediate codes although 2 pending codes that eventually became current codes after running and revving the engine P1132 2003 FORD F150 - Lack of Upstream Heated Oxygen Sensor Switch Bank 1 and P1152 2003 FORD F150 - Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2. The first time I've seen these codes, only appeared after manifold change. I did numerous checks for vacuum leaks and checked coil packs(replaced 18 months ago) and fuel injectors (new) for electrical connection problems. When I rev the engine I am now getting a white grey billowing exhaust. I checked oil and oil cap for water (none), new thermostat and water flowing ok. Never had a problem with the oxygen sensor let alone two of them! Have you experienced this issue? I would sure appreciate any recommendations and or guidance.
Hard to help with those complicated diagnostics without seeing them.....but I would start checking to see if you pinched the wiring harness when the manifold was put back on. Check the rear crossover harness on back of engine.
@@SandCarServices Thanks Ron, checked all that. I thinking my cats might be messed up, as it starts up right away and will run for a while and then it starts bogging down as though not enough air is getting in or being backed up from the cats
I did a Dorman on a 4.6 e250 very carefully and slowly all torque specs followed and so far so good, I also made sure all the bolt holes would accept those self-tapping bolts the job took me an entire month of weekends.
My intake had this exact same issue about 4.5 years ago. I took it to the dealer, and they didn't know where it was leaking from even after I mentioned it might be a cracked intake at the crossover. I took it home, removed the intake, and found it cracked exactly like the one in the video. I used this same Dorman model as a replacement - $175 on Amazon compared to $350 for the OEM. While I agree that the self-tapping connections seem pretty cheap, I haven't had an issue yet after more than 4 years and another 40k miles. 2002 Ford F-150 5.4 V8 Triton
Thank God for a positive feedback on this Dorman intake...mine went bad too and my brother in law bought me the Dorman intake for a Christmas present and I've been totally stressing about putting it on but this one comment gives me a little hope that it might fix it for a little while.. Couple years and I'll be happy but did the new Dorman intake cause your truck to drop in power and torque?
Well I can say that out of all the Dorman manifolds I've installed i have had one or two that I didn't have to warranty so its possible to get a good one. Its the long wait to see when it cracks or leaks that makes me NOT INSTALL these anymore with a warranty.
@@garyhawthorne5456 I'm a DIYer and had some challenges, but was able to get it done. A couple of the coil bolts were a struggle to reach, and there is just a bunch of stuff to take off before you can get to the manifold bolts. That much time standing on the bumper and leaning over into the engine bay was tough. I needed a lot of breaks. Overall I'd say it is challenging but doable. Just make sure you've got the time to disassemble and then reassemble everything. I wouldn't do this if I couldn't have the truck out of commission for at least two days.
@@garyhawthorne5456 For what's is worth, after 5 years the replacement manifold ended up warping in the same spot the first one cracked. It created the same coolant leak and misfires as the coolant would fill up the spark plug wells. Amazon refunded my original purchase price under warranty and I did the job again earlier this year.
Can't find a new genuine Ford intake manifold part No. 2L1Z-9424-AA for my 2001 5.4l Roush F-150 anywhere. There are plenty listed for sale at dealers, but they actually have none in stock. Local Ford dealer did a nationwide search of dealerships and also found none in stock. Manifold leaks a copious amount of coolant on the passenger side of the crossover pipe. Bought the truck new in 2001 and has only been driven 124k miles, so apparently the plastic just aged out. Will either do the changes necessary to install a pre-2000 aluminum intake or go with the Dorman brand and hope for the best.
My other comment wasn't added for some reason. If you're still looking for an oem intake quirk parts online has nine left. You'll have to call to order because the website says "not for sale" however that's incorrect. I just drove down to the warehouse in Quincy mass and picked it up since I live in New Hampshire right on the mass border. 285.00 plus tax and shipping.
Welp... going through this right now. Apparently my OG 99 Crown Victoria was part of the original recall but the owner didn't get the memo. Back in 2016 I bought the Dorman from Amazon and now, about five years later almost to the day, apparently the intake is leaking fluid on the 1st spark plug. I took my car to the shop almost once a week for the past five weeks... yet they can't get it to replicate the issue. I'm going to have to get to the Ford Dealership and pay something stupid - at least I should be able to get a refund on the original Amazon amount... but what a pain. Thank you for posting this.
Does Ford still make OEM intake manifolds for these vans? The dealerships in Las Vegas won’t touch a 2000 Ford E-250. Parts guy told me we don’t make parts for older fords anymore. It’s all dorman.
I had to replace my factory intake because all of the threaded inserts for the bolts either were spinning inside the plastic or completely broke out of the plastic same thing with fuel rails bolts. So I really don’t mind the self tapping screws at least I don’t have to worry about the bolts corroding into the brass insert. Mind you my truck is a 2000 2v with 416k miles. I got by not screwing the coils down for about a year but eventually it started leaking coolant down the plug wells causing a misfire. Took me about four hours to complete
Just a heads up. As of today, 1-20-2023 there is ONLY NINE ford branded replacement manifolds in stock in the country. There is about 700 on back order with no replacement date! So you might HAVE to use the aftermarket parts regardless. In my area of seattle washington, there is NONE in stock. I don't know where the other 9 are, but they are not here. My advice is to carefully inspect the Dorman part to ensure the holes are drilled correctly. You might have to shop around to get a "good" one.
I am glad i came across your video on this subject, was thinking Dorman for the cheap price but will run from this Doorman part with the issues you stated. I started searching for parts for the ford f150 5.4l intake replacement. The #5 cylinder misfire caused by a small coolant leak into the plug well. It looks like it might be coming from under the thermostat housing. Thank you for what you do and your views and videos! I will continue watch.
I went through 4 intake manifolds on my Ford Expedition 5.4L in 3 years, then found out that my mechanic was only using Dorman intake manifolds. The last time I needed one, Motorcraft was on strike with a 5 month backlog, so I had no choice. It works fine until I have to go up in elevation, from Phoenix 1,000 ft above sea level, to 7000 ft in northern AZ. I'm going to replace it with a Motorcraft as soon as I can get one.
I just found this video you this morning on UA-cam. I appreciate the insight and would like to add, you are right about the Dorman vs. Ford intake manifold from my experience. I replaced the manifold on my '02 E-350 and have had a high idle and it resembles overheating sitting in traffic after about 5 minutes. I believe this is due to the insulating shroud underneath the OEM not being a part of the Dorman series. I also found out the plastic molded intake is not nearly as thick as the OEM Ford intake. I have not used this old van much for business, since the replacement. i've spent the money on the Ford Intake and will be replacing the aftermarket gamble part this weekend! Thank you for confirming what I wondered for nearly a year!
I think the leaks are caused by the steel split spacers for the mounting bolts get lose under the heat. Then the plastic portion slips up just enough to have vacuum leaks.
Was forced to go with doorman. No ford dealers around me had oem in stock all on back order with no eta. Install went well besides my iac going out right after I put the manifold on.
Thanks for this video I just have one question for now so why has the dorman have one tank I guess that's what it is and ford has 2 on The underside I have the same motor 5.4 triton Thanks alot
I installed a Dorman 5.4 intake on a ‘02 5.4. F-150. The original intake was broken at aluminum crossover passenger side. My Ford dealer cannot get a replacement manifold. NAPA had this Dorman. Fit perfect. Truck runs good. Ford has known about this problem for 20 years. Or more. Plastic gaskets is what caused GM’s lawsuit over Dexcool. My next truck will be a Toyota. Or Dodge. Done with Found On Road Dead.
thanks for video!! i was wondering about that bottom shield , should i reuse or not but like you said theres no way to attach, u answered my question , thank you..
Hey Ron, I've got a 2000 F350 with a 5.4. It isn't leaking coolant but one of the brass inserts has broken loose for one of the coils when I went to replace the spark plugs, guess the previous owner put one to many ugga duggas on it, the truck has 100k miles on it. Would it be worth swapping the manifold now or just wait till it starts leaking? I plan on using the Ford OEM manifold. I was able to use a tiny wood screw and screwed it down in between the insert and the plastic to keep it from spinning and cut the head of the screw off. I needed to get on the road the following day for a job, didn't really feel comfortable with the hack job fix, but hay its holding up, so far anyway.
@@telewubby1961 Never thought of doing that, I'll keep it in mind. I still have the truck and the ol wood screw trick is still holding up to this day. I have a new in box manifold on standby lol
Hello Ron...watched your video on the OEM vs Dorman intake manifold and did purchase the OEM..We found ours had melted and so we are replacing it. Can you. tell me what the technical name is for the pipe that runs underneath the manifold coming from the water pump.
I just installed a doorman and I'm not having any luck getting it to seal! It's leaking worse now. Seems to be leaking at or around the under the thermostat housing.n
Man this is one part you DO NOT want to fail on you. Don’t take a chance in this because if you’re like me ( a diy or die) this is a lot of work that you don’t wanna do again!!!! By oem
Ron I'm having trouble with my 5.4 intake manifold I have replaced it twice within a couple of months... And I have basically figured out that at four and a half five grand (RPM)... passing gear.. the water pump stock.. is building so much pressure at high RPM is blowing the molded o-rings on the bottom of intake manifold mainly on back of Left Bank... What can I do to keep this pressure down at high RPM
Thanks for your videos ...I HAVE A 2000 F150 ITS DRIVING ME CRAZY!!!....number 4 and 1 cylinders showing misfiring codes ...changed all plugs and COP'S...AND now when I drive it it will start bucking and knocking real bad ..changed fuel filter still doing It now weird thing is if while I'm driving it and she acts up I shift her into neutral turn the engine off start her back up put her in drive and resume driving and the problem goes away for about 5 minutes or less and comes back out of no where when I slow down ....
Installed this a couple months ago on my 2001 F150 5.4 and didnt run into any of the QC issues you had, went on easy, but I will agree the self tapping screws are a little worrisome.
Shot the video before completing job. This is the last dorman manifold i will ever install in a van again. Those self tapping screws suck in a van with limited accessibility.
@@rickyjewell2385 Just bought a Dorman intake and once I get it fixed I'm probably just selling it or trading it off cause I sure don't want to do this twice
Unfortunately, the OEM part is discontinued and this is all you can get for a replacement now. Just had to order one myself and not pleased about it, but don't have an options.
@Dayton as of Jan 2023 the factory part is on back order with no fill date. There are 9 oem manifolds left in the country. Not sure where, but none are in the pacific northwest.
Hello. Good video. I have a question though....is it necessary to replace original manifold with plastic one? If so, can you explain a little why or why not?
Ron, my 1999 6.8 has an aluminum factory intake. I am getting steam out the exhaust and a slight miss for the 1st few miles. I'm replacing the intake manifold gaskets soon. Do you concur with my diagnosis? Love the channel.
I would do a leakdown test to check for the head gasket, because it will save you both time and money if it ends up being the head gasket! Not to mention that you can check all your plugs at the same time to see if you can figure out which cylinder may be getting some water in it. (and, since you are there, maybe time to change the plugs..... would love for you to reply to this with what the actual fix was.
Ok, I just completed the intake manifold gasket upper and lower. I am happy to report that was the issue. I saw where two of the intake gasket rubber o-rings had cracks in them and missing segments. I also replaced several vacuum lines, thermostat and coolant recovery cap. All is good so far.
Hey Ron great video My question is I have a 2003 Ford Excursion 5.4 50k miles I’ve notice a different smell out of the exhaust I don’t have any coolant leaks or misfires is there a way to test if I have a intake leak Thanks
Nice video 10 years ago I changed the intake manifold, the dreaded crossover leak, I just developed another leak not exactly where it's coming from have lot of coolant under intake manifold on top of block. Any sure way of finding leak Thanks
I just got the cheaper one and plan on tackling it. Should I secure the fuel rail and coils outside before I install it ? Just to make sure I don’t go crooked when it gets bolted down? Thanks. 2000 e350.
Thanks for the video. I trying this on my 5.4 2 valve. Just a question though if I may just to clarify, when installing this kind of intakes the intake itself gets placed directly onto the block with out the metal gasket correct?
Replaced my Ford intake with one of these 2 years ago, it is leaking by #3 plug now and filling the spark plug well. DO NOT BUY THIS DORKMAN INTAKE!!! Pure crap. Now I am going to have to buy the Ford part anyway plus round up all the hardware to go with it. What a mess.
Hello great video! I just replaced the intake manifold Dorman brand same one you used my 2003 ford expedition 5.4l triton and now is throwing a po171 and a po203 any advice thank you
For the p0203, Check the wiring for a good connection on cylinder number 3. That would be the 3rd back on passenger side head. The p0171 is running lean on bank 1 also passenger side. Possible air leak.
I am having the same problem with the doorman and can't find a vacuum leak and all the plugs are good....I've even gone so far as to pull it all back apart, thoroughly inspect the manifold and all parts and reinstall it using silicone on all air connections and still has the same problem and codes.....a starter fluid test for vacuum leaks shows none.....any ideas why it might be running like this when it ran fine before the new manifold? BTW also replaced all 4 injectors and tested all 4 coils on bank1
@@johnpike9612 for what it's worth, I'd check the live data on fuel trim and voltage of O2 sensors. If it's both banks it could be a MAF sensor. If your trim changes when you stand on the brake I think it's an air leak. Could be orings on the injectors as well. Would be awesome to use a code reader that has power balance to see which cylinder is malfunctioning.
Just bought a 2001 Lobo Screw with Dorman manifold. Ordered Ford OE and new updated gaskets...Dorman also has much smaller plenum which means power loss. Price difference is not much. $240 shipped. If you cannot cough up an extra C-note, better off walking.
I’m dealing with a 5.4 in a 1998 Ford Expedition. It has an upper and lower intake manifold but online I cannot find any info on what upper intake model to use. The F150 of the same year is this part number ^ but someone had suggested to use the 4.6 intake which is 6152278 which looks similar except for the coolant cross over bar has two threaded holes on the left as opposed to one on the right. My question is should I get a new lower manifold as well? My heat blanket thing fell apart on removal. Already bought the upper manifold as well as spark plugs and coil packs to replace while I’m in there. I don’t want to throw too much more money in it but also what to do the job right. Also concerned about a valve cover gasket leak as the valley was absolutely coated in grease on one bank and not the other
With the current (1+ year backorder) of OEM Ford 5.4 manifolds, the Dorman is currently your only option for a new part. Seriously, I called the only four Ford dealerships in the country that might have new composite manifolds and the ones that did have one (1) in stock would not sell it to me. The only other viable solution (and what I ended up doing) is to find a used 1999 aluminum manifold. For '99+ trucks with the PI heads, only a 1999 manifold will work... '97-98 NPI manifolds do not seal properly.
This will be the 3rd time I'm having to replace the dorman manifold. Because the gaskets are junk and leak. Any other motors I have rebuilt I always used Indian head gasket shellac to make sure I got a good seal. What's your thoughts to get a proper seal on this doorman gaskets
One of the reasons I said never again in the name of the video. Best thing to do is replace with an O.E.M. manifold. If that's not an option then you have to resort to half as repairs. I say that because you should never have to add any sealant to a rubber style seal gasket.
I have a dorman also. It leaks around the runner gaskets in 2 places. Would you recommend rtv gasket maker on the manifold gaskets if I were to take it off and redo it ?
So... Why Then, did you use this Dorman intake manifold on that van you were working on? Why did yo Not order the Ford OEM manifold? (I get your message though).
Because the customer wanted to save money and and all it did was cost me valuable time that the customer did not pay for. And these manifolds have a high rate of warranty returns. Unfortunately I had to install a few before I figured that out. This was a video to inform others so they didn't make the same mistake I did.
@@SandCarServices I figured that - My 2001 f150 with the 5.4l has a Dorman replacement intake manifold on it from the previous owner. the engine has 22,000 miles on it since this Dorman was installed. I hope it keeps doing its job. Thank you Sir.
The only problem you can’t get the original Ford stuff anymore I’ve been trying and I am unable to find an original manifold. So I have no choice but to go to an aftermarket and I feel doorman is made in the USA so that’s why I’m gonna go with them.
Bought one for my 01 Supercrew. Didn't even take it out of the box it was such a cheap p.o.s.! Sent it back and found an aluminum manifold off of a 99.
I had a question,i have a 96 T bird with the 99 head Mustang package,in 2009 my Ford intake failed and i bought a Dorman intake and everything had brass inserts to include the fuel rail, is this a relatively new thing of them installing these self tapping screws? reason i ask is because although this is a 5.4 engine i have checked the newer intakes for my car also from dorman and they also have those self tapping screws,i agree of course its a terrible idea,nothing is wrong with my old intake,i was replacing some injectors and decided to give the car a freshening up and removed the intake since i had the rail off and pretty much everything else .
hay did. you end up haveing a vaccum leak on that pvc elbow?. i have took mine off now 4 times all because of vaccum leak . the elbow will come loose about 15 min down the road . can i put jb weld or Teflon tape on that elbow or will that not work ?
My dealership says these are on back order showing 2 months out... some websites are showing it's discontinued. Dorman or the other knockoffs on eBay may be the only solution in the near future sadly.
@@100mphClub Ford dealership in Canfield Ohio has an Ebay store selling them for 220. I just bought one. My mechanic told me just to go with dorman but their 200. No way I'm buying that!
Michael Chapman Great find. I went with the dorman for less (discount through work). Old intake is off. EXACT problem he shows in this video. Health issues have slowed me down on finishing the install but I hope to get in done here soon. I’ll report back if I have any issues.
Does Ford still make Motorcraft replacement manifolds for the 2002 5.4L? I haven't called a dealership, but can't find one online. All I see are Dorman and other aftermarket brands online and at parts suppliers.
Bought an 01 F250 with the Dorman part already installed. Have noticed that lower side will flex as I accelerate. Therefore causing a delay on throttle response. Will that also happen with OEM part? I am considering an aluminum one from a boneyard.
Hi I have one nut 8 mn left holding the cross over on the left side of the engine its the skinny up side down..can I unbolt it from beneath the engine ? or its a pain in the ASS.

I have a 2000 expedition 5.4, I used the doorman, a year later it started leaking. Took it off and the gaskets were very flat and allowing coolant to seep through, I went to autozone and bought better quality ones.(you might want to replace them preventatively before installation, they were pretty cheap), has been fine for over 2 years now.

Most of the newer Dorman manifolds have the intake gaskets built into them so I'm confused did you add another gasket to the equation?
@@SandCarServices no, you pull out the existing ones, they are rubber and not glued in or anything like that. You simply pull them out and push in the new ones. Its exactly like replacing the ones on the cross over pipe they are simply wedged in there.

Hard to help with those complicated diagnostics without seeing them.....but I would start checking to see if you pinched the wiring harness when the manifold was put back on. Check the rear crossover harness on back of engine.
Sounds like leaking fuel injectors

I wish someone simply made a factory replacement intake manifold that's identical except made of metal instead of plastic.
They do
@@ScaredCivilian Who? Where is it sold?
Where can i fimd a metal one ?
No they don't. Not for this application
The early model manifolds from the Factory - 1997-1998 were metal.
My factory intake went 15 years before it leaked. My dorman made it about 1 year before it leaked.
I did a Dorman on a 4.6 e250 very carefully and slowly all torque specs followed and so far so good, I also made sure all the bolt holes would accept those self-tapping bolts the job took me an entire month of weekends.
so that's what the brittle busted up plastic box is supposed to do! Block sound and heat. I guessed right😊
Thank you for another great video.
looking at my 2001 F-150... your name keeps popping up... cool videos bro thumbs up on all ... coolant leaks led me to this... ;-)
My intake had this exact same issue about 4.5 years ago. I took it to the dealer, and they didn't know where it was leaking from even after I mentioned it might be a cracked intake at the crossover. I took it home, removed the intake, and found it cracked exactly like the one in the video. I used this same Dorman model as a replacement - $175 on Amazon compared to $350 for the OEM. While I agree that the self-tapping connections seem pretty cheap, I haven't had an issue yet after more than 4 years and another 40k miles. 2002 Ford F-150 5.4 V8 Triton
Thank God for a positive feedback on this Dorman intake...mine went bad too and my brother in law bought me the Dorman intake for a Christmas present and I've been totally stressing about putting it on but this one comment gives me a little hope that it might fix it for a little while.. Couple years and I'll be happy but did the new Dorman intake cause your truck to drop in power and torque?
Well I can say that out of all the Dorman manifolds I've installed i have had one or two that I didn't have to warranty so its possible to get a good one. Its the long wait to see when it cracks or leaks that makes me NOT INSTALL these anymore with a warranty.
Hard job to do?
@@garyhawthorne5456 I'm a DIYer and had some challenges, but was able to get it done. A couple of the coil bolts were a struggle to reach, and there is just a bunch of stuff to take off before you can get to the manifold bolts. That much time standing on the bumper and leaning over into the engine bay was tough. I needed a lot of breaks. Overall I'd say it is challenging but doable. Just make sure you've got the time to disassemble and then reassemble everything. I wouldn't do this if I couldn't have the truck out of commission for at least two days.
@@garyhawthorne5456 For what's is worth, after 5 years the replacement manifold ended up warping in the same spot the first one cracked. It created the same coolant leak and misfires as the coolant would fill up the spark plug wells. Amazon refunded my original purchase price under warranty and I did the job again earlier this year.
Can't find a new genuine Ford intake manifold part No. 2L1Z-9424-AA for my 2001 5.4l Roush F-150 anywhere. There are plenty listed for sale at dealers, but they actually have none in stock. Local Ford dealer did a nationwide search of dealerships and also found none in stock. Manifold leaks a copious amount of coolant on the passenger side of the crossover pipe. Bought the truck new in 2001 and has only been driven 124k miles, so apparently the plastic just aged out. Will either do the changes necessary to install a pre-2000 aluminum intake or go with the Dorman brand and hope for the best.
Hope I'm not too late haha the doorman is trash
My other comment wasn't added for some reason. If you're still looking for an oem intake quirk parts online has nine left. You'll have to call to order because the website says "not for sale" however that's incorrect. I just drove down to the warehouse in Quincy mass and picked it up since I live in New Hampshire right on the mass border. 285.00 plus tax and shipping.
Thank you for the info, sorry that I did not see this until it was too late.
Welp... going through this right now. Apparently my OG 99 Crown Victoria was part of the original recall but the owner didn't get the memo. Back in 2016 I bought the Dorman from Amazon and now, about five years later almost to the day, apparently the intake is leaking fluid on the 1st spark plug. I took my car to the shop almost once a week for the past five weeks... yet they can't get it to replicate the issue. I'm going to have to get to the Ford Dealership and pay something stupid - at least I should be able to get a refund on the original Amazon amount... but what a pain. Thank you for posting this.
Does Ford still make OEM intake manifolds for these vans? The dealerships in Las Vegas won’t touch a 2000 Ford E-250. Parts guy told me we don’t make parts for older fords anymore. It’s all dorman.
Thanks Ron. I will go with the Ford OEM manifold.
I had to replace my factory intake because all of the threaded inserts for the bolts either were spinning inside the plastic or completely broke out of the plastic same thing with fuel rails bolts. So I really don’t mind the self tapping screws at least I don’t have to worry about the bolts corroding into the brass insert. Mind you my truck is a 2000 2v with 416k miles. I got by not screwing the coils down for about a year but eventually it started leaking coolant down the plug wells causing a misfire. Took me about four hours to complete
Just a heads up. As of today, 1-20-2023 there is ONLY NINE ford branded replacement manifolds in stock in the country. There is about 700 on back order with no replacement date! So you might HAVE to use the aftermarket parts regardless. In my area of seattle washington, there is NONE in stock. I don't know where the other 9 are, but they are not here. My advice is to carefully inspect the Dorman part to ensure the holes are drilled correctly. You might have to shop around to get a "good" one.
Talked to ford super dealership yesterday 3/13/2024, there is no good options for 1999 5.4l. We're pretty much left with salvage & junkyards
10-24. NO manifolds from ford any more.
I am glad i came across your video on this subject, was thinking Dorman for the cheap price but will run from this Doorman part with the issues you stated. I started searching for parts for the ford f150 5.4l intake replacement. The #5 cylinder misfire caused by a small coolant leak into the plug well. It looks like it might be coming from under the thermostat housing. Thank you for what you do and your views and videos! I will continue watch.
Thank you. About to do that job so this info is invaluable.
I went through 4 intake manifolds on my Ford Expedition 5.4L in 3 years, then found out that my mechanic was only using Dorman intake manifolds. The last time I needed one, Motorcraft was on strike with a 5 month backlog, so I had no choice. It works fine until I have to go up in elevation, from Phoenix 1,000 ft above sea level, to 7000 ft in northern AZ. I'm going to replace it with a Motorcraft as soon as I can get one.
I just found this video you this morning on UA-cam. I appreciate the insight and would like to add, you are right about the Dorman vs. Ford intake manifold from my experience. I replaced the manifold on my '02 E-350 and have had a high idle and it resembles overheating sitting in traffic after about 5 minutes. I believe this is due to the insulating shroud underneath the OEM not being a part of the Dorman series. I also found out the plastic molded intake is not nearly as thick as the OEM Ford intake. I have not used this old van much for business, since the replacement. i've spent the money on the Ford Intake and will be replacing the aftermarket gamble part this weekend! Thank you for confirming what I wondered for nearly a year!
I think the leaks are caused by the steel split spacers for the mounting bolts get lose under the heat. Then the plastic portion slips up just enough to have vacuum leaks.
Great videos ron keep up the good work
Was forced to go with doorman. No ford dealers around me had oem in stock all on back order with no eta. Install went well besides my iac going out right after I put the manifold on.
Thanks for this video I just have one question for now so why has the dorman have one tank I guess that's what it is and ford has 2 on The underside I have the same motor 5.4 triton Thanks alot
Thank You! Great Information
Doorman’s manifold for ford 2000 expedition 5.4l gives the SAME Performance as the original FORD TOP MANIFOLD? Thank you so much!!
As long as I'm not expected to warranty the Dorman crap I dont care. I'll never install another piece of crap Dorman intake on a customer's car.
So when it come torque sequence on the doorman manifold correctly. Will it split the manifold if I follow the proper torque sequence?
I bought one from 1aauto that has held up for a year so far, I believe it is backed by a lifetime warranty.
I installed a Dorman 5.4 intake on a ‘02 5.4. F-150. The original intake was broken at aluminum crossover passenger side. My Ford dealer cannot get a replacement manifold. NAPA had this Dorman. Fit perfect. Truck runs good. Ford has known about this problem for 20 years. Or more. Plastic gaskets is what caused GM’s lawsuit over Dexcool. My next truck will be a Toyota. Or Dodge. Done with Found On Road Dead.
Almost every dorman manifold i installed worked great after installed...... but then........warranty warranty warranty on almost all
thanks for video!! i was wondering about that bottom shield , should i reuse or not but like you said theres no way to attach, u answered my question , thank you..
Hey Ron, I've got a 2000 F350 with a 5.4. It isn't leaking coolant but one of the brass inserts has broken loose for one of the coils when I went to replace the spark plugs, guess the previous owner put one to many ugga duggas on it, the truck has 100k miles on it. Would it be worth swapping the manifold now or just wait till it starts leaking? I plan on using the Ford OEM manifold. I was able to use a tiny wood screw and screwed it down in between the insert and the plastic to keep it from spinning and cut the head of the screw off. I needed to get on the road the following day for a job, didn't really feel comfortable with the hack job fix, but hay its holding up, so far anyway.
Two years too late. But if anyone else has this issue it is possible to buy new brass inserts and pressing a new ones in with a soldering iron
@@telewubby1961 Never thought of doing that, I'll keep it in mind. I still have the truck and the ol wood screw trick is still holding up to this day. I have a new in box manifold on standby lol
Hello Ron...watched your video on the OEM vs Dorman intake manifold and did purchase the OEM..We found ours had melted and so we are replacing it. Can you. tell me what the technical name is for the pipe that runs underneath the manifold coming from the water pump.
I just installed a doorman and I'm not having any luck getting it to seal! It's leaking worse now. Seems to be leaking at or around the under the thermostat housing.n
Had one put on my 2000 f150 5.4 , The thing started leaking two weeks, I removed it and ordered the OEM Motocraft intake and had zero issues.
Exactly what happened to my 01 5.4. Also notice a decrease in power with the dorman. Definitely junk
@@Rockymountainklx yep, Dorman is trash… My OEM intake has given me zero issues , still going strong …
Man this is one part you DO NOT want to fail on you. Don’t take a chance in this because if you’re like me ( a diy or die) this is a lot of work that you don’t wanna do again!!!! By oem
Well said
Ron I'm having trouble with my 5.4 intake manifold I have replaced it twice within a couple of months... And I have basically figured out that at four and a half five grand (RPM)... passing gear.. the water pump stock.. is building so much pressure at high RPM is blowing the molded o-rings on the bottom of intake manifold mainly on back of Left Bank... What can I do to keep this pressure down at high RPM
Same problem over here 🤔
Thanks for your videos ...I HAVE A 2000 F150 ITS DRIVING ME CRAZY!!!....number 4 and 1 cylinders showing misfiring codes ...changed all plugs and COP'S...AND now when I drive it it will start bucking and knocking real bad ..changed fuel filter still doing It now weird thing is if while I'm driving it and she acts up I shift her into neutral turn the engine off start her back up put her in drive and resume driving and the problem goes away for about 5 minutes or less and comes back out of no where when I slow down ....
is it better to just go to a junkyard essentially to find an OEM Ford Intake Manifold that's hopefully in good condition vs. buying aftermarket?
Installed this a couple months ago on my 2001 F150 5.4 and didnt run into any of the QC issues you had, went on easy, but I will agree the self tapping screws are a little worrisome.
Shot the video before completing job. This is the last dorman manifold i will ever install in a van again. Those self tapping screws suck in a van with limited accessibility.
Using this for my 2001 model as well. Is it just me or is the brass fitting it comes with is not needed?
@@rickyjewell2385
Just bought a Dorman intake and once I get it fixed I'm probably just selling it or trading it off cause I sure don't want to do this twice
Unfortunately, the OEM part is discontinued and this is all you can get for a replacement now. Just had to order one myself and not pleased about it, but don't have an options.
The Ford oem intake is not discontinued. You can order them at any Ford parts desk or online through a dealer.
2001 5.4 2V---Part# 2L1Z-9424-AA
@Dayton as of Jan 2023 the factory part is on back order with no fill date. There are 9 oem manifolds left in the country. Not sure where, but none are in the pacific northwest.
Hello. Good video. I have a question though....is it necessary to replace original manifold with plastic one? If so, can you explain a little why or why not?
Ron, my 1999 6.8 has an aluminum factory intake. I am getting steam out the exhaust and a slight miss for the 1st few miles. I'm replacing the intake manifold gaskets soon. Do you concur with my diagnosis? Love the channel.
Possible head gasket. But if problem is still there after intake manifold gasket repair then head gasket needs to be checked.
@@SandCarServices thank you Sir. Merry Christmas!
I would do a leakdown test to check for the head gasket, because it will save you both time and money if it ends up being the head gasket! Not to mention that you can check all your plugs at the same time to see if you can figure out which cylinder may be getting some water in it. (and, since you are there, maybe time to change the plugs..... would love for you to reply to this with what the actual fix was.
@@josephkessinger5973 I will get to it soon. I'll try to remember to reply. Thanks
Ok, I just completed the intake manifold gasket upper and lower. I am happy to report that was the issue. I saw where two of the intake gasket rubber o-rings had cracks in them and missing segments. I also replaced several vacuum lines, thermostat and coolant recovery cap. All is good so far.
I did end up with a duralast at autozone lifetime warranty. Alignment perfect time will tell....
The bridge isn't at the rear you said.
The heater lines run across the middle of it. ?
Hey Ron great video
My question is I have a 2003 Ford Excursion 5.4 50k miles I’ve notice a different smell out of the exhaust I don’t have any coolant leaks or misfires is there a way to test if I have a intake leak
Thanks
Ron is this a hard job to do? My 2001 F150 runs perfect No check engine light on Don't leak in summer only in cold weather
I used this Dorman product and my vehicle ran terrible after the installation.
Where can I buy the Ford OEM intake manifold
Any knowledge of a better intake manifold than the stock Ford replacement?
Nice video 10 years ago I changed the intake manifold, the dreaded crossover leak, I just developed another leak not exactly where it's coming from have lot of coolant under intake manifold on top of block. Any sure way of finding leak
Thanks
I just got the cheaper one and plan on tackling it. Should I secure the fuel rail and coils outside before I install it ? Just to make sure I don’t go crooked when it gets bolted down? Thanks. 2000 e350.
Great video. Very informative.
I used the Dorman it work fine I would recommend it 4.6 f150
There you have it friends. A successful install. All the pne I put in that took a crap were probably a fluke. Lol
Where is the shop I have the same issue on a 98 e150 4.6l
What about the URO autotecnica brand? Are they good?
Thanks for the video. I trying this on my 5.4 2 valve. Just a question though if I may just to clarify, when installing this kind of intakes the intake itself gets placed directly onto the block with out the metal gasket correct?
I have the same question here
Did you figure it out?
If using the aftermarket intake, the use of the OEM style gaskets are not required. The seals are built into the aftermarket intake manifold.
i WOULD ALSO LIKE TO ADD THAT THE DOORMAN IS THINNER PLASTIC THAN FORD.
Thank you for sharing
What about the one from 1A Auto?
Seems to be a better option
Its still from cha cha china!!!!
Replaced my Ford intake with one of these 2 years ago, it is leaking by #3 plug now and filling the spark plug well. DO NOT BUY THIS DORKMAN INTAKE!!! Pure crap. Now I am going to have to buy the Ford part anyway plus round up all the hardware to go with it. What a mess.
I'm trying to warn them.
Did one today injection ports on driverside didn't align properly never again
Hello great video! I just replaced the intake manifold Dorman brand same one you used my 2003 ford expedition 5.4l triton and now is throwing a po171 and a po203 any advice thank you
For the p0203, Check the wiring for a good connection on cylinder number 3. That would be the 3rd back on passenger side head. The p0171 is running lean on bank 1 also passenger side. Possible air leak.
@@SandCarServices thank you for the quick response. I will check for these problems
I am having the same problem with the doorman and can't find a vacuum leak and all the plugs are good....I've even gone so far as to pull it all back apart, thoroughly inspect the manifold and all parts and reinstall it using silicone on all air connections and still has the same problem and codes.....a starter fluid test for vacuum leaks shows none.....any ideas why it might be running like this when it ran fine before the new manifold? BTW also replaced all 4 injectors and tested all 4 coils on bank1
@@johnpike9612 for what it's worth, I'd check the live data on fuel trim and voltage of O2 sensors. If it's both banks it could be a MAF sensor. If your trim changes when you stand on the brake I think it's an air leak. Could be orings on the injectors as well. Would be awesome to use a code reader that has power balance to see which cylinder is malfunctioning.
@@aaronmajors6560 it definitely wasn't an air leak and we don't have the equipment for testing sensors beyond what the OBD says is wrong.....
when that manifold goes bad and leaks does it typically leak into the oilpan?
Are they all 10mm bolts for the coils and rails? I'm looking to find some not sure how to look for them
Thank you.
Just bought a 2001 Lobo Screw with Dorman manifold. Ordered Ford OE and new updated gaskets...Dorman also has much smaller plenum which means power loss.
Price difference is not much. $240 shipped. If you cannot cough up an extra C-note, better off walking.
I’m dealing with a 5.4 in a 1998 Ford Expedition. It has an upper and lower intake manifold but online I cannot find any info on what upper intake model to use. The F150 of the same year is this part number ^ but someone had suggested to use the 4.6 intake which is 6152278 which looks similar except for the coolant cross over bar has two threaded holes on the left as opposed to one on the right.
My question is should I get a new lower manifold as well? My heat blanket thing fell apart on removal. Already bought the upper manifold as well as spark plugs and coil packs to replace while I’m in there. I don’t want to throw too much more money in it but also what to do the job right. Also concerned about a valve cover gasket leak as the valley was absolutely coated in grease on one bank and not the other
I didn’t even know that dorman made stuff in the usa
Another mechanic told me some of the Dorman stuff isn't good.
Are these intakes are basically disposable. If you do the gasket you should replace the intake?
Just installed the Dorman, so far no issues and runs great! Thanks Ron!
With the current (1+ year backorder) of OEM Ford 5.4 manifolds, the Dorman is currently your only option for a new part. Seriously, I called the only four Ford dealerships in the country that might have new composite manifolds and the ones that did have one (1) in stock would not sell it to me. The only other viable solution (and what I ended up doing) is to find a used 1999 aluminum manifold. For '99+ trucks with the PI heads, only a 1999 manifold will work... '97-98 NPI manifolds do not seal properly.
Thanks Ronnie this is making me lean towards a Ford intake
This will be the 3rd time I'm having to replace the dorman manifold. Because the gaskets are junk and leak. Any other motors I have rebuilt I always used Indian head gasket shellac to make sure I got a good seal. What's your thoughts to get a proper seal on this doorman gaskets
One of the reasons I said never again in the name of the video. Best thing to do is replace with an O.E.M. manifold. If that's not an option then you have to resort to half as repairs. I say that because you should never have to add any sealant to a rubber style seal gasket.
How important is it to replace the fuel injectors when installing a new intake manifold?
If it's not broken, dont fix it.
@@SandCarServices ok...thank you👍
I have a 2000 ford expedition 5.4L and I have just one question. Will I need to reinstall a new gasket manifold?
Good job
Do you have to go to the Ford dealership to get the original intake manifold? Or can Napa get the part?
Just wondering because I’m in the middle of doing this tear down now?
Hey Ron, what is the best brand name for Ford timing chain parts ?
Motorcraft
@@SandCarServices Thank you sir !
Whats the part number on the Ford
I have a dorman also. It leaks around the runner gaskets in 2 places. Would you recommend rtv gasket maker on the manifold gaskets if I were to take it off and redo it ?
So... Why Then, did you use this Dorman intake manifold on that van you were working on? Why did yo Not order the Ford OEM manifold? (I get your message though).
Because the customer wanted to save money and and all it did was cost me valuable time that the customer did not pay for. And these manifolds have a high rate of warranty returns. Unfortunately I had to install a few before I figured that out. This was a video to inform others so they didn't make the same mistake I did.
@@SandCarServices I figured that - My 2001 f150 with the 5.4l has a Dorman replacement intake manifold on it from the previous owner. the engine has 22,000 miles on it since this Dorman was installed. I hope it keeps doing its job. Thank you Sir.
The only problem you can’t get the original Ford stuff anymore I’ve been trying and I am unable to find an original manifold. So I have no choice but to go to an aftermarket and I feel doorman is made in the USA so that’s why I’m gonna go with them.
Bought one for my 01 Supercrew. Didn't even take it out of the box it was such a cheap p.o.s.! Sent it back and found an aluminum manifold off of a 99.

No, sorry
@@SandCarServices thanks
I had a question,i have a 96 T bird with the 99 head Mustang package,in 2009 my Ford intake failed and i bought a Dorman intake and everything had brass inserts to include the fuel rail, is this a relatively new thing of them installing these self tapping screws? reason i ask is because although this is a 5.4 engine i have checked the newer intakes for my car also from dorman and they also have those self tapping screws,i agree of course its a terrible idea,nothing is wrong with my old intake,i was replacing some injectors and decided to give the car a freshening up and removed the intake since i had the rail off and pretty much everything else .
hay did. you end up haveing a vaccum leak on that pvc elbow?. i have took mine off now 4 times all because of vaccum leak . the elbow will come loose about 15 min down the road . can i put jb weld or Teflon tape on that elbow or will that not work ?
I installed the Dorman intake on my truck. After 2 years it was leaking.
My dealership says these are on back order showing 2 months out... some websites are showing it's discontinued. Dorman or the other knockoffs on eBay may be the only solution in the near future sadly.
Well that sucks
Ron Williams Better stock up. There are 4 on Amazon. lol
@@100mphClub Ford dealership in Canfield Ohio has an Ebay store selling them for 220. I just bought one. My mechanic told me just to go with dorman but their 200. No way I'm buying that!
Michael Chapman Great find. I went with the dorman for less (discount through work). Old intake is off. EXACT problem he shows in this video. Health issues have slowed me down on finishing the install but I hope to get in done here soon. I’ll report back if I have any issues.
Does Ford still make Motorcraft replacement manifolds for the 2002 5.4L? I haven't called a dealership, but can't find one online. All I see are Dorman and other aftermarket brands online and at parts suppliers.
Yes, Ford is still making most of them.
Thank you much.
Will this problem cause antifreeze in exhaust?
I frequently use these on 2006-2008 E-350s and have never had issues.
Well I have. Come backs suck. Never using these Dorman crap manifolds again. But it's still a free country you can do what you choose.
Understood, thanks for sharing.
Thanks
May i ask where the engine coolant temp sensor on 2012 e350 5.4 fuel flex engine b4 on other vans i had by termostat
Thank you
Bought an 01 F250 with the Dorman part already installed. Have noticed that lower side will flex as I accelerate. Therefore causing a delay on throttle response. Will that also happen with OEM part? I am considering an aluminum one from a boneyard.
