- In this video I highlight a 2005 Toyota Tacoma that came in with the customer complaining of a gurgling noise behind the dash and an engine misfire condition. One thing leads to another and this job takes a turn for the worse. Watch the video for tips and tricks to pinpoint the cause for similar issues on Toyota Trucks.

Thank you for your blank paper test! In the past I've used a small mirror to look for condensation in the same way but your test is much better and she won't be upset that I borrowed her mirror ever again. My 07 FJ at 194,000 miles just blew a head gasket. Let the good times roll!
2005 and some 2006 4.0’s have a different head gasket. They were determined to be faulty after quite a few miles. The part numbers are even different showing Toyota changed the design.
A recall would’ve been nice lol. My 2005 Taco been blown for a while but the thing has been chugging along for almost a year with a known head gasket failure, and likely been bad for 5+ years lol (that’s when major misfire issues began, coils started going bad). Noted. Don’t buy a 05 or 06 again lol.
Your teaching approach is "down to earth" to watch! You don't say extra stuff that don't matter! Thanks! You are cool to watch! Thanks for the video!
Thank you so much!
Headgasketitus is an all too common issue with older vehicles... engineoilleakitus on the other hand can strike at an early age. Keep'em healthy Doc!

Just subscribed! The engine on my Tacoma overheated and the mechanic believes because it was going on for a while the block is now warped. It was regularly and recently maintained as well. I believe I would have caught it just from watching this video....Thank you in hindsight and I look forward to going through more of your videos
Thank you. This is exactly what is happening to my 2005 Tacoma. Great video.
So what did you do? Was it coils or the head gasket? I have an 06 with 275K.
@Daniel Fiore mine was a head gasket leak. I used a head gasket sealer and it seems to have worked.
@@RealEstateAgentSFthanks for the response. Was it throwing a code?
@@danielfiore8865 no code. The sealant stopped working. And the engine would overheat within about 40 minutes. I had the head gasket replaced. Running well again. 245,000 miles.
Super helpful vid, have the same exact symptoms on my 1GR-FE 4Runner. Going to follow the same troubleshooting steps but it’s looking bleak… thank you for the video!
Toyota ought to be reimbursing us for all these head gasket failures.
This video confirms my thoughts and I thank you for your professionalism after a nightmare / disaster of a certain business / techs that worked on my 2006 Tacoma. I ended up with a bad knock sensor and a bad head casket due from the repairs this business and their techs performed which was a total nightmare of replacing the crank seal "TWICE" with oil leaking all over the place, 3 drive belts being installed wrong "3 TIMES", a pulley going bad from wrong drive belt installation, a serious overheating taking place while on the road causing the vehicle to be towed "TWICE"! Which has now lead to a bad knock sensor and a bad head casket.
Lame
This is a good video. I just went through this with my 08 V6 with 295k miles. I started losing coolant with no noticeable leaks. No check engine lights or issues driving. I pressurized the cooling system like shown here. I borrowed an inspection camera with side view ability and watched a single drip of coolant come out of the head gasket run down into the cylinder. Both cylinder #6 and #4 were leaking. Another possible indicator is a white spot or cleaned area on top of the pistons. The coolant steam cleans the pistons which cause the white or clean look. This was very noticeable on #6 for me.
Did you get this fixed?
@@proxyicarcus Yes, I replaced the head gaskets. I finished it right before Xmas last year. Took my time over the period over a month or so. Put about 6000 miles on it since and it just turned 300k miles a few weeks ago. So far so good.
Errosion arround small coolant passages nx 2 cyls in block in hi mile 1grfe's also causes this. Block must B resurfaced
My 2005 Chevy Duramax with only 144,000 miles on it and yep, head gasket blown. But guess who fixed it? Eric O's brother Doug. Nice video Tim. Good tips along the way.
Eric O brother...cool
We have a 2006 145k miles. Light smoke like cigarette smoke from the tailpipe, idling little rough, water drip from tailpipe, coolant goes low maybe half a court between oil change. I'm thinking head gasket.
this is common on 05 and 06 4 litres also the timing cover leaks in same years
I have a 06 4Runner V6 with a bad temp sensor and the motor is feeling rough at 1500-2000 rpm. I don't hear a gurgling sound, but it's more of a ticking behind the dash. I am losing some coolant though.
. I spent the month of December at the dealership, but no definitive answer where the disappearing coolant to my 2006 Taco, going. Refused boroscope since held pressure for 10 minutes at 15psi. Passed Block test, but wasn't given the opportunity to witness the tests.
Ck engine light also an issue p0012, serv advisor jumping gun replacing VVTI gear partial engine tear down, $1200, instead of simply replacing the VVT control valve $300, but eventually replacing the vvt valve (no chg) which cleared the code. However was decided to replace the vvti gear (twice) at sane time vvt valve replaced against my instructions to replace the vvt valve first, to identify exact part causing the code and get $1200 refund since repair failed and did not follow diagnostic tree. (Chg oil, ck timing chain, chg vvt valve, then gear if needed). Serv advisor also sold me set of rear struts, making me think alls well with the engine (didn't need struts, brakes yes, engine, definately!) Timing off, lost 1/2 resovoir coolant since filled 12/13/22, RPMs off and refuese to even disconnect battery so computer can relearn RPMs.
Will do Block test myself and see what happens. Did see another video where mechanic used an emmission/Exhaust prope placing it in the coolant resovoir after vehicle warmed, measuring for exhsust gas, and tested positive, following a block test which was negative. Unfortunately in Fla, we are not required to pass emissions and no one has the equipment. The Car Nut utube video, also did a boroscope with pressure test, and small trickle of coolant observed in number 4 cylinder.
Thank u for the video.
If you get this head gasket job please make a video...I need to pull the cams on this same engine but don't know enough about it and even the manual is vague when it explains cam alignment and the preload tension...
That's why I wasn't too anxious to get the job. We will see what shakes out. He took it home for now. Maybe ill get it back this winter when it gets slow
The Car Doctor everyone on forums attempt this job and end up with valve tics and power losses and inevitably scrap the whole project
OH crap, lame. I bet I could get her done right but probably loose my butt doing it.
I know you could do it right that's why i hope you get the job and make like a 2 hour long video
but it would probably end up being a two day long video and I would have to edit out all the bad words.
Thanks for the great news but riddle me this why come when I put injector cleaner in my engine light went away and the misfire. It is now back and I have had the gurgling😅.not kool
Would love to see the head gasket repair, If you get the job.
Gosh, that would be a lengthy video...possibly R rated. haha
I like the paper test need to do it next time.
Definitely helped. Just means I blew a head gasket fml but thank you!
OH crap. So sorry
Ouch that's going to be expensive for the taco owner. Nice palm light Tim I was just looking at that one too. I have the autel bore scope - it sucks big time but better than nothing. $60 and if it breaks tomorrow I won't miss it.
Does the autel have good clarity on the screen of detail? I agree on the price, nothing lost if I drop it or something.
I can see well enough and it does magnify as well . When I had the oil sensor leak in the back of my LS engine I found the leak with it and it did its job. I have never used anything any better but for the money it works good. Check the tip dia. - mine looks almost too big for a spark plug hole. There's lots of options including the PC based endoscopes too. Look forward to seeing what you get. For you it's a must have . Cheers
Thanks. I think 5 or 6 mm is as big as you want.
So this means Toyota isnt reliable like everyone says or thinks.
For example The 2nd gen Highlanders share the same engine as the Lexus RX350 problem with those is if the timing chain cover gasket is leaking you have to drop the whole engine to replace it.
Now there is your famous reliability from Toyota. Not sure what happened in the mid 2000's quality control from Toyota took a huge dive.
I mean, most of these engines still last 200k+, even if this starts to happen they can manage for a long time past that unless it gets catastrophic.
But yeah, they still have had some mishaps. Too many dif engines and builds to keep everything dialed in perfectly.
Great video, would you recommend doing a compression test also to rule out if replacing a head gasket is justified if the rest of the cylinders are toast?
Definitely helpful! Thanks!
How often do u get OBDI? Those are fun. You don't have a nice computer and 30 sensors to tell u exactly what the problem is. It's back to basics, good hearing, more time, etc
I seem to get a lot of that old school stuff. Sometimes its a breeze but believe it or not sometimes complicated to pinpoint issues that nowadays would be a quick fix. Not sure why but 99-200 Chevy early vortec motors have been eating my lunch on diagnostic issues lately.
Can leaking oil from valve cover into spark plug well cause same misfire? I getting P0304 noticed oil around end of plug when I replaced. My plug did not look wet but had carbon buildup. Getting interment P0304 error. Replaced plug and coil but error came back. Changed oil and it looks clean, still see some oil around base of plug. I don ‘t hear that noise you spoke of.
What is Cylinder head min and max thickness and what is allowable warpage on cylinder heads. Was the block deck resurfaced too?
Keep up the good work tim ur the best !
Awesome video thanks for sharing Tim. I hope you have a blessed week my friend.
Thanks. Blessing right back at you buddy. Its going to be a great week!
very simple and helpful diagnosis.
Aw crap 💩 I think I have this problem one my 04 4Runner 1GR-FE engine.
Missing at start after warmed up & water coming it of tailpipe.
Will/Can a block seal additive help for a temp fix the mistake problem?
How about on the same engine 1GR-FE when you get foamy oil on the cap, is this same problem different area?
Thx🙏🏼
I'm considering buying a 2006 Tacoma Prerunner TRD 4-door with 128K miles. What are the major issues I should look for when inspecting this Truck? I heard engine mounts might be a problem. Based on this video, it sounds like I should also check for head gasket problems. What else? Separately, you asked about thoughts on replacement borescopes. Consider searching for a used SnapOn borescope on Craigslist. You might be surprised and find one. I see lots of used SnapOn tools on that site.
Thanks for the tip. I replaced the imager on the snapon and its back up and running. What motor in the Taco? Wheel bearings, driveshafts, cats, and transmissions are a common deal for sure.
The Car Doctor The engine is a 4.0L V6. I don't have the engine model number. Would it be more helpful if I provided that information or was there only one model of the 4.0L V6 for 2006? How do you rate this engine in terms of power, reliability and gas consumption relative to other trucks in its class? I'll definitely have a closer look at the maintenance concerns you mentioned. By the way, your video is very helpful. Thumbs up.
@@ThecardoctorTV RUST
I have a cheap scope that plugs into a USB port that I use with a laptop. It work really good and was around $20. How can I tell if its a head gasket or a cracked head? My daughters boyfriend was told he has a cracked head or head gasket. They said they could tell which one it was, because they couldn't drive it up to 30 MPH. He had bad tie rod ends too. What does driving it at 30 MPH have to do with anything??? I never heard of anything like this. Love your video's
Youll probably have to pull the head and have it tested to determine if its cracked. Not sure on the 30 MPH deal. weird
Very educational brother. Thank you so much!
Great video, will help my diagnose my 4R, thanks!
Great video and excellent commentary. Thank you so much
Thank you!
Thanks for posting, liked the vid. See you on the next one.
Thank you
Thanks for the video! I appreciate the paper test!!!!
I have a 06 SR5 4runner . I need to clean the vvt filter but cant find it . Do you know where it is ?
How much does fixing this cost
Did the customer ask you to do a head gasket job?
Sucks for the owner, but nice vid Tim.
Agreed. Thanks for dropping by
Very helpfull video my friend , thank you so much !!
Just came across this video, I subscribed. Did you get or are you getting this job? The job sucks. Toyota doesn't recommend repairing head bolt threads on the ends, have to replace the short block. You can try Time Sert inserts, they hold for a while but seems like after many heat/cool cycles on these you end up where you are now. Sadly, you'll probably end up pulling some of the threads out on the ends when you remove the bolts. Double check knock sensors and wiring while in there, its a real nice design also.
I declined doing this job. I was too busy at the time and not really into that type of work unless its slow. Ill have to follow up with the guy and see what he had done and how it turned out.
Know problem with the 05 they have a updated head gasket for them are you going to film the job. Thanks cory
I don't think ill be doing this job but consider video if I do. Have you done them?
The Car Doctor Hope you do get the job. I would not trust anyone else if I were the customer. Removing the head is a really good opportunity to go over stuff that could cause problems in the future.
Thank you so much Sir! Very helpful
Glad you liked it.
I've got a 2005 Tacoma with a blown head gasket. . This truck has been well maintained. . What causes this to happen.
Shawn Bramucci how long did you drive it when it started misfiring?
Thank you so much sir :)
Yep its a shame the gasket is gone, but i cant think of any better person than yourself to fix the problem :-).
The customer would be silly to take it elsewhere.
I hate to say but I want him to take it elsewhere...I haven't done many of these engines and IM too busy for another learning experience right now. Ill probably regret that come mid winter when the phone stops ringing. haha
Thanks for the informative video.
I have a similar diagnosis issue on my 2005 Tacoma (but no Check Engine light) and about a year and a half ago I had it to a dealer and they said it was fine, just topped up the fluid a little (wasn't below min, just not full). since then it has continued but not gotten worse. How long could this continue to be fine?
Well? How long did she last?
How costly is the repair ?
Thanks
I'm concerned my 07 has this issue, I have a low battery voltage code and a p0300, found coolant reservoir bubbling topped off coolant in radiator it quit bubbling.... are the 07s effected also or just earlier ones?
bubbling in the coolant reservoir is a pretty good indicator of head gasket issues.. was that your problem?
11/05 was the last month that the old head gasket was used. 12/05 was the first month of production for the new gasket design.
exactly what i have thank you
Would a bad head gasket causes the fuel to mix with the oil ?
Maybe coolant to mix with oil but not so much gas.
Funny looks and sounds like the truck I'm going to do in afew days
Great vid, Tim. How many miles on that truck?
133K on the clock
"Toyota Quality" is like the Loch Ness Monster--Everyone's heard of it, some claim to have seen it, but the only real proof is some blurry photos from the 1980s.
Thankyou.
What was the mileage on that?
The 2005-2006 4.0 has a problem with the headgaskits, normally around 125k-150k.
@@TheILLogics 04 v6 4runner here. 275k miles and head gasket finally blew. Exactly the symptoms this gentleman mentioned. Guess I got lucky making it this far.
If the plug did smell like fuel what would that tell you?
I believe that is what it's supposed to smell like
Did you do a combustion block test using that blue fluid before doing all this other stuff? I'm curious on how to accomplish that with the reservoir tank on my 5th generation because the cap is actually part of the recirculation system, you remove the cap to do the block test...
Having trouble with a chrysler 200 with a pentastar. Car overheats after 20 minutes of use and quickly cools down at idle. Has new radiator and condenser due to the car being wrecked previously. Already tried Purging the air out of the system so many times with no luck. Any suggestions. I'm thinking a small headgasket leak. You can see after the car heats up that the water isn't circulating on the return hose on the reservoir.
Car doesn't smoke steam or have misfires.
is the fan working properly?
Yeah both speed on both fans work
maybe using an infrared thermometer could give you some info about whats going on. Radiator clogged, thermostat bad, poor circulation from a bad water pump (common)
Did a chemical block test at operation temperature and won't change for a blue green color
Love your videos watch them all the time ,how much would you charge to get that head gasket fixed
It aint cheap. But in this case if we rebilut the heads and all that it would be pushing $4000
I just went and test drove a 2018 with the 4.0 and a 6 speed manual. I was thinking about trading my 2012 Z71 in on it. I actually love my Silverado it has gave great service but I’m just sick of driving an automatic. The taco is one of the few trucks I can find with a manual still in it. Are the 4.0s junk? I had an 08 tundra I bought and drove for four weeks and traded it because it had a knock in the engine with 60k miles on it And an older couple had owned it and it had all the service records so that makes me a little scared of Toyota Plus all the head gaskets ive helped put only on 22 RE’s That were supposed to be so great. I’m supposed to go back to the dealership tomorrow so they can appraise my Chevy. I’m not gonna go if these things are giving trouble.
3rd gen Tacomas (2016-current) don't come with 4.0L motors. Those were only used in the 2nd gen Tacomas (2005-2015). Among these model years, the earliest always had more issues. Much fewer than a GM product but issues did exist nonetheless. The head gasket problem was rectified 2007-on so if you're buying a 2nd gen, aim for 2007-2015. If you're looking to get a 3rd gen with the new 3.5L , go for 2018+. Some early 3rd gen Tacos had issues with leaks from factory. That being said, I know PLENTY of people who drive early-model-year Tacos for 300k+ with no problems but if you're looking to avoid potential issues altogether, go with the years I listed. If you have any questions, feel free to ask.
@@TYLERTRANCE
I have a 2nd gen tundra 4.0 ,6 colander.Its used with 160k.Great on gas,but a taping noice under the hood.Dont know what to make of it.I mean runs great,should I be worried.First time truck owner.
@@arturorodriguez374 It's valve tick. Completely normal for these motors. Lots of people do 300k+ without ever doing a valve adjustment. Lifters by design will tick a little bit but if you're really worried you can always have someone check clearances. Shops and dealerships might tell you not to bother with it.
@@TYLERTRANCE thanks buddy.
Is this a common problem with this Toyota 4.0l v-6 engine??
Only on early year models. Toyota fixed it after 2008. Despite that, I've seen 2005-2008 Tacoms in the 300k range. Only a small fraction of the early 2nd gen Tacos had the head gasket issue.

That's the glamour shot of me!
I have the Snap-On's best borescope but I got a great deal on it but my next borescope if needed will be an articulating borescope that I used scoping aircraft and aircraft engines. you don't have to keep twisting the scope around and messing with the spiral cable trying to get the right angle. This is the one I am looking at www.automotivetestsolutions.com/ic.html it has a 3' cable 6mm head and will work good for snaking thru HVAC ducts and the articulating head helps you turn corners and scoping engines is a breeze. I hate spending a few hundred on a piece of equipment and find out I can't do something with it but if I spent the $$ to get the one I wanted I wouldn't be staring at a car wishing I had what I needed. It's all about how good of an image you want and what kind of detail to you want to see. Nice life hack with the piece of paper...improvising using the melon :D The ending made me smile!
haha, I couldn't help but laugh for some reason. I was sad for my customer since he just dropped some cash on struts and now this. I priced the new imager for my snapon unit but it was more than I paid for the original unit. Maybe I can get a used imager off a defective unit. Thanks for the link, ill check it.
That's so soon on a toyota engine!! How is the felpro mls??
IM not sure the best gaskets to use here. I like felpro but there may be a better set on this motor
The Car Doctor which one is better?? Victor Heinz??
Lario... I ended up replacing the motor... You are right, not mant Toyota techs know how to do this work properly. Comox Valley Toyota denied any wrong doing... Auto fruad, piss poor workmsnship...no warranty on workmanship... It is always after the fact... You pay good money to have a repair done..mistakes are make...but it is the LIES AND EXCUSSES which is sickening... Comox Valley Toyota has leadership issues also...they all cover each other butts...they have too. Couple of tips though... (which this dealership NEVER did) mark everything and take pics during disassembly; dual overhead cams..timing, shims (do not mix the order) hsve your heads chkd by pofessional machinist/ re-surfaced/seal replaced..and any other work needed; replace head bolts ans they are torque to yeild... These were 3 things Comox Valley Toyota DID NOT DO ... I should have pulled the motor and did it myself... Take one's time .. By the book, it is a 20-24 hr job.. This dealership did it in 14 hrs... Rushed and screwed up... They could NOT even remember what they did...1-1/2 months after they did the work when asked be another Toyora dealership... Go figure... Anyhow, there are videos out there..and they will help...but when tearing down, and reassembling engines...keep things clean and check everything... You may be better to buy a rebuilt engine...
Awesome video, you da man.....
thanks, another one bites the dust
The Car Doctor
Yep, but on a Toyota?
afraid so
Cool
ant
I wonder what caused it to fail? These are usually great trucks
I guess they had issues with gaskets on this vintage. Seen it a few times but not like the old subarus or anything
260;000 and having that problem now
I have a 2012 Tocoma (4.0 ltr) - had a local Toyota dealership do work on the engine (said they replaced head gskts) and since then. this engine has been consuming EXCESSIVE amounts of engine oil and coolant; Engine oil consumption is at 2/3 ltr of oil PER TANK OF FUEL; Coolant, the engine has consumed about 4 ltrs SINCE the work performed at this Toyota dealership; WHAT A BATTLE.... Dealership refuses to take responsibility for the failed work (IF IT WAS EVEN DONE PROPERLY); 6 other dealership say it is them who needs to take responsibility; Even Toyota Canada's "Oil consumption test PROVED there was a problem and FAILED this test; Finning Oil analysis showed coolant being burnt in combustion chambers .... hence possible pressurization of other cylinders and then blow by...and EXCESSIVE OIL CONSUMPTION... What a Battle....STILL
Moose Racks my 2005 has head gasket leak, minor, but I have he,d off getting it repaired because of stories like this. It seems no one can do the repair properly. Post an update if you would.
I just test drove a 2018 4.0 with a six speed manual. I loved the truck but Reading these comments I may stick with my 2012 Chevy Silverado it’s been as loyal as an old friend.
Wut the hell thought toyota tsvomas never fail
Get a bore scope that plugs into your phone they are like $20 and if it breaks who cares cause its $20
is the image quality very good? I cant see well is why im asking.
yeah eric o used a cheap one and found a chipped valve so i would say the quality is good...plus for $20 you could get like 3 different brands and make a video on which one is best
Why do y'all love it when it's something serious??
i sucked sum of my coolant out of my 4.0 4runner...smells like gas. I keep losing coolant,..white steam out of tailpipe. no codes. Head gasket?
@viradiasp im in Northern California
Yes it sounds like it.
I'm in northern California as well
Do you think more frequent coolant changes may have prevented this?
I don't think that was the cause here but its possible in some cases to be caused by lack of service and corrosion. I think they have issues with the actual gasket material design from what I understand
You mean cylinder 6.
😢
How much Doc?
not sure. I bet its $4000+ for O/H on both heads
OMG! Not a good day for owner!
Man that sucks 😞
Yes. Very sad.
First alaskan comment
Nice! Where at?
Stick a Cummins into it and ship it down the road 😂😎
What? OH my no way. haha
That video sure helped....unfortunately....crap
Oh bummer
sounds spensive
Very helpful, thanks
