2007 4Runner V6 Valve Cover Gasket Replacement

- This video covers the recent repair I did on our 2007 V6 4Runner. The valve cover gaskets were leaking pretty badly, and I could tell why when I went in to replace them. All the gaskets were brittle. I wasn't too concerned about a bit of oil seepage on the engine block but when it got to the point we could smell burnt oil coming off the engine from the leaking gaskets that's when I decided to get this done. Even then I bought these and had them sitting around in the hall for a month before finally getting the job done.
It took about 4 hours to get everything completed with half that time just getting the air intake plenum and hoses etc off the top of the engine and out of the way. You will likely be able to do it a fair bit quicker as I wasn't really following any video or manual, just figuring things out as I went along. It sure made me doing the same job on our 03 Tundra seem simple by comparison.
The tools I used for the repair were....
10 and 12mm sockets
Impact drill
8mm hex bolt driver
shop rags and q tips
razor
Parts Cleaner
gasket and grommet set
Toyota 103 FIPG sealant

This is totally a project you can take on if you like to work on your truck, have some patience and a bit of time.
Comprehensive, thank you. Not a lot of videos on this specific job and I appreciate your contribution to the cause. 4th Gens, especially the early ones are notorious for valve cover gasket leaks and up until very recently there weren't good resources to DIY this. Thank you for digging in and giving us something meaty to know what we're getting into.
Thank you Sir. Glad you got some use out of the video. It’s not a terribly hard job, just frustrating getting through all that driver’s side mess. Enjoy the project if/when you get to it.
Thanks for taking the time to make this video mate. Without it I would of tried to do this myself. After watching what you went through I’m definitely taking it to my mechanic
awesome VIDEO
fixin to do
09 FJ soon
Is your rocker covers leaking as you didnt use a toyota branded rocker cover gasket (blue)- toyota brand is black- and you didnt grease the upper part of the gasket. Curious to see if you stopped the leak?
No leaks on this truck or our 03 Tundra that I did around the same time.
Great video, thank you. I initially looked 1st gen Tacoma 3.4 V6 replacement required other parts. Do we still need intake manifold gasket to have ready just in case, not to mention spark plugs....
What brand was blue color gasket and part # ? Last but not least - drivers side gasket looks easiest to replace, and it's only slightly leaking on my truck at dipstick area, perhaps not losing oil, would it be worth to go for both, or just one in a simplest way?
Hi there. Thanks for watching the video. I’m not sure what the part # is for a 3.4L v6 as mine is a 4.0L. I think if you’re taking all those things apart anyway you may as well buy the parts you ‘might’ need like the intake gasket. If you don’t need to change it then just take it back for a refund. If you haven’t changed your spark plugs in a while then for sure change those. And clean the Mass Airflow Sensor and the throttle body too while you have everything open.
On the 4.0 at least the driver side is much harder as the air intake plenum etc takes a lot to undo. If your driver side looks easiest and the passenger side isn’t leaking I’d get the whole kit but just do the drivers side for now and then hold onto the passenger side gasket if you need it down the road
Thanks a lot, meant that have same 4.0 V6 engine on 2nd gen. Tacoma. Yes, will get both sides, and do the easiest passenger's first. What was brand # of yours, I like blue color. Also there are intake upper plenum gaskets, wonder if those needed and how many.
@@evgenyaleks1696I didn’t see any gasket under the air manifold on my truck. The link to the felpro gaskets is in the description of the video
I had the same kit. Came with o rings and rubber grommets. Could not figure out what they were for and couldn’t find anything on the internet either
Same here. It only had 3 grommits on the center bolts. I definitely didn’t find any more orings on the original tear down
Hey I have same issues on my 05 4Runner just noticed this issue but have to drive about 300 miles to get home before I can get this to my repair shop. Should I be okay to drive ? So far noticed oils leaking exactly where your are. And been checking my oil levels so far not that bad. Should I just continue to monitor the oil before I drife back home next Wednesday?
I don’t imagine that much oil is coming out so if you check the engine oil level and top it up if required then I imagine you’d be fine. Mine was seeping for years before I finally got around to fixing it.
Thanks for the vid! Did you need to drain the oil or the coolant beforehand?
No need to drain anything. I checked the coils and spark plugs to see if they needed replacing but they were good so just popped them back in.
This video has helped me immensely. The only thing I am wondering is about these valve cover grommets. Do they only go on one cover? FelPro supplied 12 grommets but each cover has 10 bolts to remove.
That’s a great question. I wondered the same thing when I got the kit. I just spread the new grommets around with some of the old and just focused on getting the torque values right. I also did the same repair on our 03 Tundra and both have been great ever since. The 4Runner smelled horrible after it was running for a bit with the dripping oil burning on the engine. Not a problem since changing the gaskets though.
12 bolts total on each side but 3 grommets go on each side ontop of the valve cover
Great video, im not sure if I missed it in the video but do you know the torque specs for the valve cover bolts? thanks!
Hi Chris. They’re 8ft/lbs of torque. (96inch pounds).
@@OffroadGrindAppreciate it!
How long was the process including trial and error?
Hi Justin. Sorry I missed your comment, I was away in Colorado for a bit there. I think I mention it in the video but I seem to remember it taking 2+ hours to get everything out of the way on the drivers side and about an hour to actually change the gasket and put it all back together again. The passenger side was an hour to remove everything and an hour to change the gasket and put it back together.
If you think there are too many hoses and clamps, try one with the lpg conversion. Lol that's what i got myself stuck into today. 😅
Thanks so much this helped me out a lot
About to try it out on my 04 v6 SR5 wish me luck 🤓
PSN you got this pal. Going to feel so good when it’s all done and you don’t see (or smell) that darn oil leak anymore. Let me know how it rolls for you
Will do, lightly washed the engine surface to clean up what I could and let it sit. Haven’t ordered any parts yet I should be able to get the off the shelf at orileys or the Toyota place.
@@OffroadGrind new covers in, only mistake I made was not grabbing the gasket maker while at Toyota. So after a short trip there and back I also realized I didn’t have the 6 washers for the bolts by the coil packs. But I just used what I had since they had some life in them. Old gaskets were completely dry rot and crumbled in my hand. Also while disassembling the intake and valve covers I decided to take everything off the top and have a complete open work space which helped with debris.
wow did it go? i'm doing mine next saturday!😁
Boy you created a lot of headache by not undoing a couple more hoses and connectors. Always torque valve cover gaskets in a criss-cross pattern starting at the middle and working your way out to the edges.
Right on. Thanks for the advice. Maybe include the link to your TH-cam channel and video showing how to do it properly !! As you can tell from the comments there’s VERY little info online on how to do this. Instead of complaining about how I did it maybe provide a better example of how to do it properly. But thanks for taking the time to complain.
So disconnect battery?! Lol
14:25 hahahahah i was thinking the same thing gotta be an easier way. so many hoses and brackets and stuff in the way.
You forgot to put grease on the upper part of the gasket!
Ummm, I hope you don’t use grease on a silicone gasket. If anything you’d use a silicone lubricant. That’s totally optional though and it’s not to seal the gasket, that’s what the gasket is for, it’s to let it slide a bit if required. I don’t need that so didn’t use it and it worked perfectly the way I did the repair. But thanks for your thoughts.
You totally should have cleaned all hoses etc before ripping it off. All that grit straight in
Haha. Thanks for the thoughts. I think it worked out perfectly.
WEAR GLOVES. Otherwise awesome video, thank so much!!
Ha, I’m old-school. If I wore gloves every time my hands were about to get dirty they’d be constantly wrinkled. I save the gloves for when I’m using solvents etc or painting and want to keep the oils from my hands off the piece I’m finishing. Grease and oil doesn’t warrant me wearing gloves. I’d rather just use my hands, get them dirty and clean them afterwards.
