How to - 4.7 V8 Valve Cover Gasket Replacement w/ Pictures

Seal Washer p/n?

Does anybody know the part number for the seal washers that go on the bolts that hold down the valve cover? My dealership can only find the bolts with the washers already installed and they are "out of stock indefinitely".

"Toyota Maintenance" on youtube talks about replacing the seal washers:

hectorh,
Not sure exactly which one you are asking for. I am guessing this one?

Toyota PN 9020110133

Not that one. The one you indicated is a metal washer for the cylinder head bolts.

But thank you because I did not know about partsouq.com. It's now in my bookmarks. :thumb:

Looks a little like sludging. Put some in a metal container and see if it completely dissolves with a good cleaner, like brake clean.

This is what the black stuff looks like once I stir it with brake clean. I think it's definitively dirt and not sludge

hwell:

I was cleaning the dirty cover when I noticed that one of the corners is lifted higher. This is also the area where the worst damage is located.

I happened to find my oil filter from last year's oil change, opened it and look at what I found inside

I'm going to be opening every oil filter from now on. This issue has been going on for over a year. Before that, all maintenance was done at the dealership.

Now I have to figure out how to remove the oil pan with the front axle in the way.

The bolt and washer are included in the purchase of the bolt. I just recently purchased #90080-10330 and the washer was included. Purchased from McGeorge online

90080-10330 X 18
11214-50011 X 1
11213-50031 X 1
11193-50010 X 8

No leaking noticed on my 2004 but I've only put on a couple thousand miles since last post.

I bought yet another 4th gen V8 last week. 2003 with 117k miles. Same valve cover leaking situation so I tightened those boots too. My mechanic voiced his opinion against my doing that...said the gasket material was likely all dried out. His charge to remove the covers, clean, reseal with new gasket stuff, including I guess doing something at each induction coil, $750-ish. That's doing it all "Toyota" as he's a Toyota master mechanic. If the problem becomes recurring I'll probably look deeper in to doing something like that.

I know this is an old thread, but can you recommend the mechanic or shop that suggested your valve cover gasket replacement? And if you did it did he resolve the issue? I live in OC but would drive a bit to find a good Toyota master mechanic. Pretty sure I need my gaskets replaced but my local dealer is screwing me over big time and I want to find a Toyota specialist. Thanks.

I ended up taking the truck to a different mechanic that I started using in October 2021, which is The Toy Shop on Sepulveda Blvd in Torrance. Much better pricing that the first mechanic I referenced in my previous post you quoted. Plus, they are fine with me getting my parts myself, they just won't guarantee them. I only use OEM and can get good prices so I usually go that route.

I've had these guys do a lot of work on my 4Runners since then, and they will also replace the starter on my LX next week. Zero complaints so far.

Don't mean to revive an old thread but I'm not able to start my own yet.

I was working on removing the driver side valve cover and had a hard time removing the hose that connects to the PCV valve. While I managed to disconnect the hose, I broke the plastic 90 degree elbow that comes out of the intake manifold.

I searched around and was unable to find the name of the part or a part number to replace it. Does anyone know what it is?

Opening up an older thread… is there a particular order that the valve cover bolts need to be tightened in? I’m looking at the Fel-Pro kit which claims to have everything, so I still need to order new bolts from Toyota? Thanks!

Watch youtube video "Toyota Valve Cover Gasket Job Tips & Tricks" by Toyota Maintenance, Peter will show you how to do it right. Only thing I didn't do were the half moon gaskets, mine were firmly in place. I broke 3 capscrews trying to get them out, probably first time cover ever off on '03, I soaked them every night for a week before too.

Well getting the valve cover off was pretty easy. My plugs at the back didn’t move either, so I left them alone. The spark plug seals were super difficult to get out. I ended up using a small screwdriver and a hammer to separate the metal ring (covered in very old rubber) from the valve cover. Then the screwdriver could just bend it out. The new ones were difficult to get in too, I put a bit of oil around the edge to help them go in. They don’t seem to need to go in all the way, as when you put the valve cover on the tubes will force them to seat… hopefully. Thanks for the help, fingers crossed no more leaks!

If you didn't break any capscrews then it was a success! If it leaks after, you can always do it again knowing no capscrews will break, so it's easy. I do agree, the old, hardened spark plug seals were a PITA to get out! I sanded and painted a pair of used valve covers I bought on ebay before I did mine so I wouldn't be in a rush, just painted the originals a few weeks ago ... metallic blue, they look nice hanging on the wall!

Good write up, I'll be tackling this project soon after taking care of the cats on an '04 I recently bought

It’s it seems lots of people seem to snap the valve cover bolts when removing. A Toyota mechanic on YouTube said he always uses an impact on valve cover bolts because the impacting is less likely to twist the head off. He claims to have never broken one.
