Martin, I want to thank you for the excellent video and instruction regarding what I initially thought was a very intimidating job for a non-professional. My son and I used your video (and one other about removing/installing cylinder heads) extensively to rebuild his Jeep Liberty 3.7 which had a dropped valve seat. Neither of us are mechanics but after watching your videos, we both said "we can do this!". And we did! After everything was put back together, we both held our breath as we turned the key to start it - and it fired right up. For anyone considering doing this job, just watch this video (over and over), follow the steps exactly, and you will be successful. In fact, setting the timing was the easiest and most enjoyable part of the job.
Thank you Mr. Martin, my neighbors think I'm a professional due to your step by step instructions and tips. Please know you are appreciated by so many of us who wouldn't be able to Master the 4.7 V-8 Magnum without you!
I'm so glad you've taken the time to do the videos on the 4.7L's. I was dreading doing this job but you're so clear and concise with your instructions and tricks for helping folks tackle it. I'm more excited about this now. I'll likely do the 08 cams and intake on my 02 now as well.
Hi Martin, Thank you very much for this video and tips and information. Your gentle narration is very professional. My customer's Dakota dropped a seat on the right bank making the valve stick open. Same thing on the left bank but unfortunately the number one piston and valve fought it out with the broken up seat chunks to mutually assured destruction. New heads, one piston, and a timing set are now installed thanks to your help. Nothing like a mentor to come alongside.
Well Martin, thanks to you I just tackled this and I am buttoning everything up right now. I watched this several times and followed right along with you. Thanks for taking the time not going so fast. Just got to put valve covers on, radiator in, and a few other things. Hopefully she purrs like yours when I finally turn the key. 👍
a rocker arm fell off on cylinder 2 , put it back on but still loose. I used the washer trick under the lifter and stayed there. Forgot to adjust the timing belt which makes the engine run rough. I watched this video and turn the balance shaft to match TDC and run like a champ. Thanks a lot for this video. You saved me 1500 on repairs
I assume that you have done a number of these 4.7l's then? Ever have one jump time at initial crank? I just did one, reused tensioners, everything looked good. This isn't the first one I've done either. Hit the key to start it and it instantly jumped time on both heads. Even after retimiing it, I have zero compression on the passenger side and 60 psi on the drivers side. I even primed the oil system the second time, which was too late. Is priming these needed?
My friend I just saw this video because I bought a 07 Liberty 3.7 with weak valves, it runs but missing and with this video I am going to do it myself. THANKS A LOT FOR SHARING IT WITH US. GOD BLESS YOU.
You're very welcome. With the 3.7, there is the additional balance shaft that needs to be timed with the idle sprocket. Other than that, the process is exactly the same as the 4.7
Thank you for making this video. I wish there were more videos like this for other makes out on UA-cam. Really professional filming/lighting, you have lots of great tips, you’re not cheesy or arrogant. Almost done replacing the timing set on a junkyard 4.7 that I’m going to install in my Dakota shop/beater truck and I can’t tell you how much I appreciate this.
This engine is so clean it looks like it came from a museum!! But a great tutorial that I've watched at least 6 times now. Amazing videos! I like how you work.
@@saulzavala9806 Did you soak the lash adjusters in motor oil for a day or so? This will work out the air that is trapped in the lash adjusters. And how is the oil pressure? It would be a good idea to run 3/4 quart of Marvel's Mystery oil with the next oil change. I use this in both my 4.7 engines.
Just finished doing my timing chains, guides and hydralic tensioners, got the timing cover on my rebuild. Thanks so much for your video I watched it during my install several times to get everything done correctly, so far so good on the 4.7 rebuild again thanks for the videos.
Thanks for this. Primary tensioner broke for me too in the same manner. Got one next day for $28 bucks. I'm sure this is a common event. Probably should replace it anyway due to the brittle nature of the plastic. Good video.

I've watched several different videos on this... Martin thank you. Kept it simple, answered question before having to ask. Lol just a true professional and instructor. Thanks again
Thanks for the video. Great instruction with all the visuals and tips. I watched as a refresher ( tore one down, didn't get heads back for 3 weeks 😢) I feel alot more comfortable taking on this rebuild.
I've see a few really good UA-cam videos, and a lot of bad ones. This is the best one I've ever seen. No annoyingly loud canned intro music, clean editing, great preparation and organization, excellent lighting and camera work, and thorough instruction. Thanks much. I'm hopeful that you just save me a couple thousand dollars.
Your video has been more helpful than anything that I have looked at to build my confidence to tear into my 2005 4.7 ram 1500 that has a sloppy loose passenger side timing chain that I found while changing lifters that I thought were causing all of the racket in there.

Hello Martin. I am really enjoying your videos. So informative and easy to understand. I have 04 Dakota 4.7L getting ready to rebuild heads and timing chains. Your videos should help me tremendously. Thank you!
Incredible video man. Got a 2017 trailhawk that just started a rattle yesterday that I suspect is a timing chain issue. After watching this video and the other showing how to remove the cover, I'm less apprehensive tackling this myself. Your video could save me a ton of money. You explained everything like no other I've ever seen.
I just want to say thank you in advance. This video is so well done. My truck dropped a valve seat on the #8. Fortunately there is no piston head damage. I will using this to set up my timing chain. Again, Thank you so much!
Thank you Martin!! I'm currently in the middle of doing my timing chain on my 04 3.7 Dakota. You have the best video out. I feel confident doing the job after watching your video. Detailed and not too fast. I'm watching this video and have my Haynes repair manual open. Thank you! 👍🏽👍🏽👍🏽
Thanks Martin! Helped a ton, along with your balancer installation video! Just did head gaskets, timing, and the whole works. Had to replace the heads, they were cracked between every cylinder. Thanks for making a quality video!
Hi, Just wanted to say thank you for a couple of your videos. This one on replacing the timing chains and sprockets and the one on installing solid lifters. I had to tear the heads off my WK grand cherokee to replace some bent valves so I decided to change all the valves, the valve springs, seals and put solid lifters in. I also replaced the timing chain and sprockets along with the water pump and belt tensioner and new fuel injector connectors. Little bit of work but it runs great now. Thanks again.
No, after I installed HO cams the bolt on the drivers side cam came slightly loose, guess I should’ve put locktite on ie, and the timing went off just slightly and caused the 4 intake valves on the drivers side head to hit pistons and bend. The pistons were fine but not the valves. Alls good now. Painful lesson learned though.
@@jerrymcmanus9366 sorry to hear that, I would be surprised if the bolt actually came loose, what have seen is that you may have thought the cam gear was seated to the cam but in actuality, it is not, and then the cam gear slips and you end up with bent valves and the appears to have come to loose.
@@martinbuilt thats very possible. The pin or dowel was damaged too. I’d include de a pic but looks like UA-cam doesn’t allow for that in this message area.
Usually I work with a Honda 1.7 old engine with one timing change you helped me a lot with my Jeep I miss the timing and chain I mean did Mark on the chain for the left side but other marks are good the engine rotates by hand with no problem don't think I'm good thank you for your help
I put a 4.7 from a 03 Durango into a 01 dakota and because of the timing difference between the two it wouldn't run so I sent it out to multiple mechanics to try to get it running and they all failed so the project got pushed aside now after doing research and ordering new parts its time to put new timing gears and chains and stuff on but ive never done the job before so thanks for making this awesome how to boosts my confidence alot.
@@matty2helpfull yes you can use the old one. you will need to pull the engine and disassemble the lower half of the engine to lift the crank out far enough to change it out. you may be better off finding an engine that had the NGC ECM and sell that engine.
@@martinbuilt I need to pull the engine again anyway to pull change the wire harness again so I will probably just continue with this one but I'll keep that in mind thank you for all your useful info 😊
Best video I found on a 3.7 very very good explaining everything ... the video was like a 1 on 1 person teaching me thanks alot sr keep up the good work
Nice video! Now I just wish you'd come on over here and do it for me. Lol my tensioner just went in my 04 Cherokee. It's middle of winter and I live in an apartment building. Just ordered all the parts and now I'm going to be watching all your videos repeatedly till they come in. Thanks for the very well explained videos. You're a life saver.
marten Ive worked on cars for 55 years.. Ive noticed that all these cars have plastic backed timing tensioners,,, Like you thoughts on removing the plastic and building back with brass and machining to specs. after watching you , you know what your doing.. thats rare these days. keep up the good work,,
I found out I'm also missing the guide pins. I Uninstalled first cause my buddy who was helping me broke a guide pin and some pieces fell at the bottom. Also I made my chain fall off from its spot. But yeah I'm glad I saw this video.
awesome video I have never attempted this but after watching this video i can do this. very methodical, informative on bolt sizes and what steps to follow camera coverage view well done so you are able to see the whole area where you are working. your verbal skills teaching are great. thanks
I watched your video until I had it memorized because it was the most detailed and it went absolutely flawless. My only issue was the LH cam sprocket/gear from Cloyes was not marked "R - V8 - L" (only had "L") and it was missing the holes for the spanner tool. I wanted matching gears but I needed the motor fixed ASAP. So using the old gear as a template I drill holes in the new one so I had a place to attach the spanner tool to torque the cam shaft gear bolts. Hell of a way to cut corners by not drilling two holes and deleting three stamp impressions. Great info, thanks for your hard work putting this video out there. Updated 12/7/2022 -- I replaced timing chains and lifters hoping it would get rid of the famous 4.7 tick and it did for about 4 days but then came back - strange why 4 days then returned ? Updated 12/12/2022 -- Had an oil leak on passenger side valve cover . Didn't have new gasket fully seated at rear corner-- it rolled over and some how got cut. Took about a week for the oil to find the exhaust manifold. Replaced with new one and no leaks. Reply Reply
Hey @MrGoliat6288 I have the same truck and it just started having a knocking sound that seems loudest from underneath toward the back. But I could be mistaken. But the sound doesn’t go away once warmed up. And is pretty loud. Just curious if you had the same symptoms with truck before doing the timing job. Through research, it seems to me that if it were the lifters starting to go bad the sound goes away after a bit. Thanks for your time. Also Martin you’re the best. Very helpful.
Hey man, I love your videos!!! Was wondering if u could do more step by step videos on the Dakota.. like removing the engine/ transmission.. how to find A/C leaks.. How to change transmission fluid and differential fluid, spark plugs, alternator, etc .. also how to wire lightbar to Hibeam switch
Hi Martin! Great video and thanks for doing that. There's just one more thing to watch out for on the "3.7" however. Behind the double gear assembly , there is a counter balance gear that must be properly lined up as the new gear and chain set is being pushed on.
I almost just stuck stuff together because it wasn't mentioned and I figured it wasn't important. IT IS. Prior to putting the chains on, look at the very back angled teeth for a dot. Use a grease pen to mark the tops of those 2 teeth since you won't be able to see it once the chains are on. Then when installing, put the dot on the counter balance gear in those teeth so when pushed in place, the dots will be lined up.
@@Ronnie-zn9sx are you sure you got them all? Did you remove the belt tensioner, there is a bolt hiding behind that, and the large bolt at the very top of the cover 17mm deep socket?
@@martinbuilt i found the infamous missing bolt, just where you said it was. I had to find it before i went to bed or i wouldn't sleep. Keep you updated.
Glad I found your video, because I’ve seen two other guys that made job difficult, but you do it in a way that is easy to follow. Thank you so much.. I’m retired at 73 and was engine rebuilder back in my early years
I wish you had done this sooner😅 . I did one of these almost 6 years ago an I couldn't find hardly any info on it. Needless to say that motor never ran again. Great video though thanks
Sorry I wasn't there for you then. Yes this is something that you definitely don't want to mess up. Since this is an interference engine and valve damage can certainly happen if you get the timing wrong. Thank you for watching.
Nice video Martin. Nice clear shots on the video. I had a diagnosis of coolant in my oil in my 08 3.7. So I'm considering pulling off the head gaskets. While I have all that off I gathered I might as well go the extra step and do the timing chain as well so this was very helpful. Not to mention, I just remembered since I'm doing all that I might as well throw in a new set of lifters.;) thanks!
Amazing video!! My 2004 WJ 4.7 V8 has 152k miles and wondering when I'm gonna need to do this job?? But with this video, I'm confident of 'doing' the job... Thanks
Excelente video, thanks so much, I have jeep liberty 2007 3.7, I am not expert in mechanic but likes works in cars. Your video helps a lot. From salt lake city utah usa
Great job martin! Im a bit concern about your oil pan containing debries tho. My 04 jeep came from a "dealer" and it's been a guessing game locating parts that where taking off and never went back in the car. Thanks to you i managed to put some of them back. Cheers man!
Nice video Martin you're the man! If you did go ahead and remove the hydraulic lash adjusters and rocker arms, you would be able to spin the cam sprocket by hand and not have to mark up your cams to install the chains. Really made my life easier just taking them out. Take care and thanks for the video !
Is there agive away on the need for a new timing chain set? Noise at start up when cold? Is there a particular noise to listen for? How to tell if may actually be lifter noise. Is there a mileage at which it would be wise to replace. If you include these diagnostics in your videos I believe they would be as helpful to your audience as the repair procedures. Thanks, good job!!!!
Also..the passenger side has full compression and the driver side doesn't have full compression. The second spark plug on the driver side is where my mechanic is having the problem due to the compression test that he did earlier today as of Thursday. I hope this extra helps out so I can have my truck back Friday. He's had it for 2 weeks now. Thank you again
Great video!! So the 08 camshafts have more lift and duration. I have 147,000 on my 4.7 and she runs like a champ. I take good care of her. Changing fluids when called for. 04 Dakota i have. Thanks again!
THANK YOOUUUU for mentioning to DIYers about AMAZON PARTS!!! I have to explain this to customers who want to supply their own parts on a regular basis. Unfortunately, sometimes they've already bought their own stuff (so ya really wonder where the diagnosis came from too 😉 lol). Depending on the vehicle and what kind of part it is, I end up either giving them the whole disclaimer first (1.it may not fit correctly, if it doesn't and I have to alter IT, anything else, fabricate something or spend extra time in any capacity to make it fit, you will be charged for that extra time 2. The part may not fit at all in which case i still need payed for my labor time, and if put back together will be another separate labor charge when the new part comes. 3.your part may not work properly or at all directly out of the gate in which case i will not be held liable, i will double and triple check to ensure proper installation but beyond that will need payed a separate labor charge if it jeeds replaced again, or a separate diagnsotic fee, should a new symptom arise where that same new part ends up being deemed the cause). OR i will not even accept the job at all.....pretty much anything Bavarian, Scandinavian or german/Eurotrash....im not even gonna waste my own or your time and/or money trying to fix ANY problem with amazon parts 😆 don't buy those junk rides if u can't pay to play
Hey my idler sprocket didn't have any "end play" after installing the idler sprocket bolt. Is that a bad sign? I use the original sprocket that came with my 2006 4.7 dakota, its stiff and i had to use sum force to get it on
Very important I think you did this but the tensioner only takes a plate on the driver side the left passenger side tensioner doesn't get a plate as far as im researching!
Hopefully, none of the valves made contact with any pistons as this is an interference engine. I'm glad you found it helpful.😎 Good luck with the timing chain set.
@@martinbuilt The engine wasn't running. I was installing some HO cams and the chain wedge slipped off. and the chain fell off the idler. I almost got the radiator out. Man, I thought the valve springs were the hardest part. Man, Now I gotta do this in the WJ,
@@martinbuilt When it comes down to changing valves springs in the vehicle having the cams out is a huge leg up. That Jig of yours removed the sketch factor. It only works properly centered, concentric to the stem. Thus applied there is no wasted, guess work. Unnecessary exertions are removed, believe it or not the passenger Side rear most set of valves springs we’re not the most difficult. Your tool takes time to determine the proper approach. There’s a 45° slot cut in one of them so on three cylinders I was able to do two springs intake and exhaust without moving the jig. If that doesn’t save you time. And you know that you got your retainers in right because you’ve got time on your side unless your compressor cocks out you got all day to stay in there and align everything and make sure everything is perfect. As long as you’re not standing on your air line, like I didi, t’s near fool proof.
@@martinbuilt I went with the competition cams valve springs and freshened up the top end per your recommendation. In fact valve springs when you Get right down to it are the foundation of Performance. Also installed FelPro valve seals and low profile Molebnieum valve caps.
Look I got 2004 jeep grand Cherokee 4.7 just rework the heads and new timing chain got back together starts fine runs really good but when you try to give gas it's blows the injector fuse I didn't put new injectors in but I did clean them
Thanks so much Martin! Followed your video to a "T" and it worked out great! Many many thanks! In the video you had mentioned an upcoming video on oil pan gasket/windage tray. Has that happened yet ? I've looked for it but no luck.

Glad you found my videos helpful. Did you have a timing chain failure that caused the bent valve?
No, after I installed HO cams the bolt on the drivers side cam came slightly loose, guess I should’ve put locktite on ie, and the timing went off just slightly and caused the 4 intake valves on the drivers side head to hit pistons and bend. The pistons were fine but not the valves. Alls good now. Painful lesson learned though.
@@jerrymcmanus9366 sorry to hear that, I would be surprised if the bolt actually came loose, what have seen is that you may have thought the cam gear was seated to the cam but in actuality, it is not, and then the cam gear slips and you end up with bent valves and the appears to have come to loose.
@@martinbuilt thats very possible. The pin or dowel was damaged too. I’d include de a pic but looks like UA-cam doesn’t allow for that in this message area.

Excellent Martin, man!
Usually I work with a Honda 1.7 old engine with one timing change you helped me a lot with my Jeep I miss the timing and chain I mean did Mark on the chain for the left side but other marks are good the engine rotates by hand with no problem don't think I'm good thank you for your help
I put a 4.7 from a 03 Durango into a 01 dakota and because of the timing difference between the two it wouldn't run so I sent it out to multiple mechanics to try to get it running and they all failed so the project got pushed aside now after doing research and ordering new parts its time to put new timing gears and chains and stuff on but ive never done the job before so thanks for making this awesome how to boosts my confidence alot.
Thank you, you will also need to replace the 32 teeth to a 16 TEETH CRANKSHAFT RELUCTOR WHEEL
@@martinbuilt that should be a part that doesn't get worn out right? Can I just swap from the old motor to the new? Or should I look for a new one
@@matty2helpfull yes you can use the old one. you will need to pull the engine and disassemble the lower half of the engine to lift the crank out far enough to change it out. you may be better off finding an engine that had the NGC ECM and sell that engine.
@@martinbuilt I need to pull the engine again anyway to pull change the wire harness again so I will probably just continue with this one but I'll keep that in mind thank you for all your useful info 😊
"I made a tool for that"... wow
Best video I found on a 3.7 very very good explaining everything ... the video was like a 1 on 1 person teaching me thanks alot sr keep up the good work
Wow, thanks!
@@martinbuilt how do you use the tool to get passenger sprocket on and off with the rivets in the 2 holes? I've a 3.7
Nice video! Now I just wish you'd come on over here and do it for me. Lol my tensioner just went in my 04 Cherokee. It's middle of winter and I live in an apartment building. Just ordered all the parts and now I'm going to be watching all your videos repeatedly till they come in. Thanks for the very well explained videos. You're a life saver.
Yeah, I grew up in Iowa, hated working on vehicles in the winter.
marten Ive worked on cars for 55 years.. Ive noticed that all these cars have plastic backed timing tensioners,,, Like you thoughts on removing the plastic and building back with brass and machining to specs. after watching you , you know what your doing.. thats rare these days. keep up the good work,,
I found out I'm also missing the guide pins. I Uninstalled first cause my buddy who was helping me broke a guide pin and some pieces fell at the bottom. Also I made my chain fall off from its spot. But yeah I'm glad I saw this video.
awesome video I have never attempted this but after watching this video i can do this. very methodical, informative on bolt sizes and what steps to follow camera coverage view well done so you are able to see the whole area where you are working. your verbal skills teaching are great. thanks
Thank you Paul.
I really appreciate that. I'm glad you liked it and found it helpful.
Keep the videos coming for 3.7L engines. Thank you.
I watched your video until I had it memorized because it was the most detailed and it went absolutely flawless. My only issue was the LH cam sprocket/gear from Cloyes was not marked "R - V8 - L" (only had "L") and it was missing the holes for the spanner tool. I wanted matching gears but I needed the motor fixed ASAP. So using the old gear as a template I drill holes in the new one so I had a place to attach the spanner tool to torque the cam shaft gear bolts. Hell of a way to cut corners by not drilling two holes and deleting three stamp impressions. Great info, thanks for your hard work putting this video out there.
Updated 12/7/2022 -- I replaced timing chains and lifters hoping it would get rid of the famous 4.7 tick and it did for about 4 days but then came back - strange why 4 days then returned ?
Updated 12/12/2022 -- Had an oil leak on passenger side valve cover . Didn't have new gasket fully seated at rear corner-- it rolled over and some how got cut. Took about a week for the oil to find the exhaust manifold. Replaced with new one and no leaks.

wondering how that worked for you!
@@andybilakshow260 It worked great, with no after affects
Martin you’re the man. Thanks for the videos. Just finished a timing chain on 05 Ram 1500.
Thank you, glad I could help!
Hey @MrGoliat6288 I have the same truck and it just started having a knocking sound that seems loudest from underneath toward the back. But I could be mistaken. But the sound doesn’t go away once warmed up. And is pretty loud.
Just curious if you had the same symptoms with truck before doing the timing job. Through research, it seems to me that if it were the lifters starting to go bad the sound goes away after a bit. Thanks for your time.
Also Martin you’re the best. Very helpful.
Hey man, I love your videos!!! Was wondering if u could do more step by step videos on the Dakota.. like removing the engine/ transmission.. how to find A/C leaks.. How to change transmission fluid and differential fluid, spark plugs, alternator, etc .. also how to wire lightbar to Hibeam switch
Hi Martin! Great video and thanks for doing that. There's just one more thing to watch out for on the "3.7" however. Behind the double gear assembly , there is a counter balance gear that must be properly lined up as the new gear and chain set is being pushed on.
Yep, that's right ✅👍
Yes and now here I am stuck unsure how to time that small gear..
I almost just stuck stuff together because it wasn't mentioned and I figured it wasn't important. IT IS. Prior to putting the chains on, look at the very back angled teeth for a dot. Use a grease pen to mark the tops of those 2 teeth since you won't be able to see it once the chains are on. Then when installing, put the dot on the counter balance gear in those teeth so when pushed in place, the dots will be lined up.
thanks for tips made my job a whole lot easier. ive been a mechanic for 20yrs and thanks to people like u i learn a lil more everyday👍🏿
Thank you Fred glad I could help.
I know exactly what the "YEAH!!" feels like! Very, very nicely done! Way to go!!!
Not yet
if you don't mind marring up the cam shaft, you can use pliers instead of the cam gear tool to get the cam bolts off.
I was gonna do a video on this. But then I saw yours and thought “Why mess with perfection”? Really nice job bro.
Thank you I appreciate that i'm glad you liked it.
I have a 2.7, this video was the best at explaining the essentials of timing. It is a good guide, I hope I can find one this good for my engine.
Thank you, Ronnie, I appreciate that, good luck.
Any ideas on why the cover will not come off?. All bolts and pulleys removed .
@@Ronnie-zn9sx are you sure you got them all? Did you remove the belt tensioner, there is a bolt hiding behind that, and the large bolt at the very top of the cover 17mm deep socket?
@@martinbuilt i found the infamous missing bolt, just where you said it was. I had to find it before i went to bed or i wouldn't sleep. Keep you updated.
@@Ronnie-zn9sx glad you found it, now comes the fun part
Glad I found your video, because I’ve seen two other guys that made job difficult, but you do it in a way that is easy to follow. Thank you so much.. I’m retired at 73 and was engine rebuilder back in my early years
Thank you for providing that information and how to do the timing chain
You are very welcome. I'm glad you liked it and found it helpful thank you for watching.
Never seen the zip tie technique before - great idea
I'm glad you liked it and found it helpful. Thank you for watching.
I'm liking these little 8 engines more and more.
Glad to hear that
Best How-to video I ever saw. Thank you!
Thank you I really appreciate that. I'm glad you liked it and found it helpful thank you for watching 😁
I wish you had done this sooner😅 . I did one of these almost 6 years ago an I couldn't find hardly any info on it. Needless to say that motor never ran again. Great video though thanks
Sorry I wasn't there for you then. Yes this is something that you definitely don't want to mess up.
Since this is an interference engine and valve damage can certainly happen if you get the timing wrong.
Thank you for watching.
Nice video Martin. Nice clear shots on the video. I had a diagnosis of coolant in my oil in my 08 3.7. So I'm considering pulling off the head gaskets. While I have all that off I gathered I might as well go the extra step and do the timing chain as well so this was very helpful. Not to mention, I just remembered since I'm doing all that I might as well throw in a new set of lifters.;) thanks!
Thank you I appreciate that. Glad you liked it and found it helpful.
good luck with with your engine hope everything turns out well.
Thanks for the video, this helped me out a whole lot. What’s the best way to clean up the timing and valve cover surfaces?
Amazing video!! My 2004 WJ 4.7 V8 has 152k miles and wondering when I'm gonna need to do this job?? But with this video, I'm confident of 'doing' the job... Thanks
The best information on this timing chain on UA-cam! THANKS
Thank you Travis, I appreciate that.
I'm glad you liked it and found it helpful.
Excelente video, thanks so much, I have jeep liberty 2007 3.7, I am not expert in mechanic but likes works in cars. Your video helps a lot. From salt lake city utah usa
I'm glad you liked it and found it helpful. Thank you for watching.
Great job martin!
Im a bit concern about your oil pan containing debries tho.
My 04 jeep came from a "dealer" and it's been a guessing game locating parts that where taking off and never went back in the car. Thanks to you i managed to put some of them back. Cheers man!
Nice video Martin you're the man! If you did go ahead and remove the hydraulic lash adjusters and rocker arms, you would be able to spin the cam sprocket by hand and not have to mark up your cams to install the chains. Really made my life easier just taking them out. Take care and thanks for the video !
Glad you found it helpful
@@martinbuilt sure did its nice to see the job clearly explained the zip tie trick made it so easy thanks again!
Thanks Martin! Great beard btw. Do you have footage of putting the gaskets together for the timing cover reinstall.
Glad someone finally made a great video. Thanks for informative job
Thank you . I really appreciate that. I'm glad you liked it and found it helpful.
@@martinbuilt I've been looking for head bolt torque specs. I have seen 4 different videos and all 4 tell different specs.
highly recommended video for this engine
Thank you
Is there agive away on the need for a new timing chain set? Noise at start up when cold? Is there a particular noise to listen for? How to tell if may actually be lifter noise. Is there a mileage at which it would be wise to replace. If you include these diagnostics in your videos I believe they would be as helpful to your audience as the repair procedures. Thanks, good job!!!!
I'll be doing this to my Dodge Ram 4.7 here soon. I'm glad you posted this. I'll be studying everything you've done.
Glad I could help.
Also..the passenger side has full compression and the driver side doesn't have full compression. The second spark plug on the driver side is where my mechanic is having the problem due to the compression test that he did earlier today as of Thursday. I hope this extra helps out so I can have my truck back Friday. He's had it for 2 weeks now. Thank you again
GREAT JOB BRO....IM GOING TO DO MY 3.7 JEEP SOON JUST NEEDED SOME INSTENTIVE...MOPAR FOR EVER...!
Thank you, the 3.7 has a added balance shaft to deal with.
Thanks for this! Good work! I will be doing mine soon and will follow every step.
Glad it was helpful!
Great video!! So the 08 camshafts have more lift and duration. I have 147,000 on my 4.7 and she runs like a champ. I take good care of her. Changing fluids when called for. 04 Dakota i have. Thanks again!
Thank you, Victor I am looking for Dakota regular cab 2wd for my next project.
THANK YOOUUUU for mentioning to DIYers about AMAZON PARTS!!! I have to explain this to customers who want to supply their own parts on a regular basis. Unfortunately, sometimes they've already bought their own stuff (so ya really wonder where the diagnosis came from too 😉 lol). Depending on the vehicle and what kind of part it is, I end up either giving them the whole disclaimer first (1.it may not fit correctly, if it doesn't and I have to alter IT, anything else, fabricate something or spend extra time in any capacity to make it fit, you will be charged for that extra time 2. The part may not fit at all in which case i still need payed for my labor time, and if put back together will be another separate labor charge when the new part comes. 3.your part may not work properly or at all directly out of the gate in which case i will not be held liable, i will double and triple check to ensure proper installation but beyond that will need payed a separate labor charge if it jeeds replaced again, or a separate diagnsotic fee, should a new symptom arise where that same new part ends up being deemed the cause).
OR i will not even accept the job at all.....pretty much anything Bavarian, Scandinavian or german/Eurotrash....im not even gonna waste my own or your time and/or money trying to fix ANY problem with amazon parts 😆 don't buy those junk rides if u can't pay to play
happy for you, that would rattle my confidence, thanks for the build
Hey my idler sprocket didn't have any "end play" after installing the idler sprocket bolt. Is that a bad sign? I use the original sprocket that came with my 2006 4.7 dakota, its stiff and i had to use sum force to get it on
Very important I think you did this but the tensioner only takes a plate on the driver side the left passenger side tensioner doesn't get a plate as far as im researching!
I appreciate you for this video Mr. Martin!
I'm glad you liked it and found it helpful. Thank you for watching 😊
This was a great detailed how to video, thank you 👍😁
Thank you Dave, I'm glad you found it helpful.
You should make a video on replacing valve seals to buddy
In this video I replaced the valve stem seals and installed the 08 camshafts.
ua-cam.com/video/MN3c94VevEM/v-deo.html
Super super super video! Thanks Martin from the UK!!!
You seem to be the man in the know and I don't know
Hey, when I did this I just took all the rockers off before taking the chain off. No interference at all while setting the camshafts to the chain.
My cam timing chain skipped a couple teeth, I don't want to pull the motor. This is perfect.
Hopefully, none of the valves made contact with any pistons as this is an interference engine.
I'm glad you found it helpful.😎
Good luck with the timing chain set.
@@martinbuilt The engine wasn't running. I was installing some HO cams and the chain wedge slipped off. and the chain fell off the idler. I almost got the radiator out. Man, I thought the valve springs were the hardest part. Man, Now I gotta do this in the WJ,
@@jamesdewer oh got it. What valve spring compressor did you use to replace the valve springs.
@@martinbuilt When it comes down to changing valves springs in the vehicle having the cams out is a huge leg up. That Jig of yours removed the sketch factor. It only works properly centered, concentric to the stem. Thus applied there is no wasted, guess work. Unnecessary exertions are removed, believe it or not the passenger Side rear most set of valves springs we’re not the most difficult. Your tool takes time to determine the proper approach. There’s a 45° slot cut in one of them so on three cylinders I was able to do two springs intake and exhaust without moving the jig. If that doesn’t save you time. And you know that you got your retainers in right because you’ve got time on your side unless your compressor cocks out you got all day to stay in there and align everything and make sure everything is perfect. As long as you’re not standing on your air line, like I didi, t’s near fool proof.
@@martinbuilt I went with the competition cams valve springs and freshened up the top end per your recommendation. In fact valve springs when you Get right down to it are the foundation of Performance. Also installed FelPro valve seals and low profile Molebnieum valve caps.
For the cam shaft holder, maybe a very small strap wrench? I haven't looked for one, but that seems like a possible solution.
Yes that would work as well.
Thank You Sir for quite detailed tutorial. Huge help!
You are very welcome. I'm glad you liked it and found it helpful.
Actually my current project, great video. 👍👍
Thank you, Henry
Look I got 2004 jeep grand Cherokee 4.7 just rework the heads and new timing chain got back together starts fine runs really good but when you try to give gas it's blows the injector fuse I didn't put new injectors in but I did clean them
wow ,great vid!!!! i may end up doing this , due to horrible ticking sound , dont know if its lifters or chains, the do have slack ....
Is most likely a lifter as you said or the hydraulic tensioner going bad
@@martinbuilt just now installed valve cover and added 1 quart of trans fluid to flush motor oil that gunky
Well got it figured just need to make something to hold the cam gears to torque them
I'm glad you found it helpful thank you for watching
@martinbuilt ya the only thing is you should use the dots on the gears to time it and not the windows. But ya very good video
Thanks You this help much more than manual
Thanks so much Martin! Followed your video to a "T" and it worked out great! Many many thanks! In the video you had mentioned an upcoming video on oil pan gasket/windage tray. Has that happened yet ? I've looked for it but no luck.
I'm glad you liked it and found it helpful. Unfortunately, I have not made the oil Pan gasket video as of yet. Thank you for watching.
Amazing quality video. Job completed easier thanks to you!
Glad it helped!
