looks like someone tried to pull the head without removeing the secret bolt in the puddle of oil.

Egar

aaahhh...just saw youtube video with the bolt you are reffering to..so how big a job is it to replace this? can i still find new aisin cover for it? looks like a big job! if i took it to a mechanic what would be a fair price to fix this? any additional info would be apperciated.
maybe one of you guys has a spare cover you want to unload??

New timing covers could be had from Engine Builder pretty cheap.

If you had to pay to have this done the labor would be about what it costs to do a timing chain less the parts for the timing chain.

Is it time to do the timing chain??:wabbit2:

Egar

engine builder? u have a link ? did a yahoo search but not sure if that is correct site. thanks
i just pick up this 4runner about 2 months ago so dont really know history. i know the previous owner dropped some money into it. really nice upgrades and took the time to do things right.

his shop is in Portland Oregon I've been there they're good folks.

lotta work to replace the cover I've done dozens of timing chains.. Its just tedious. Look up 22re timing chain writeups it'll answer all your questions.

When you do your timing chain go ahead and pull the oil pan. It's kind of a pain but in my case I found broken pieces of piston. So mine turned into a rebuild. Not trying to scare you but if you get that far in you may as well fix everything needed.

when my old 20r had a crack there, it would leak out the oil under the dizzy. i pulled the dizzy and the bolt, covered the bolt in grey permatex and torqued it back down. it never leaked afterwards and i never had to replace the timing cover

blake.nemitz

granted not the right way to fix but the cheapest

The other possibility is that the bolt was over-torqued upon installation (ask me how I know). Mine was a brand new cover and the crack was clean. I prep'd the crack and JB Welded it . 2 years later and still no leaks. Its the only thing I've half-assed on this truck and so far so good.

Egar

May be a couple weeks before i can buy cover... So i can permatex the bolt inside under valve cover or i can jb weld the crack from outside right?. I may have to do that for a temp fix.

angrybob

I cleaned the outside surface with brake cleaner then applied the JB weld. It was meant as a temporary fix too, but like I said, two years later...

cant hurt to try it ,it wont make it any worse.

when i did my chain i found out some one had completly broken it off and had goobered it with sealer. it wasnt leaking so i did the same.not proud of it, but it still doesnt leak. also pulling the pan is always a good practice during a maintainance tear down. just to keep your oil screen clean from the plastic that wears off your t-chain guides. causes low oil pressure.

Egar

right never hurts to look in the oil pan. i will do that when i do tear it down but for now i think the jb weld is they way to go for now. i hate oil all over the place. this was making its way all over the engine. funny part was i was looking for a leaking seal an low and behold a crack in the timing cover...

I just replaced my valve cover gasket and was very confused why i still had an oil leak in that same spot.

Looks like my timing cover is cracked as well.

I will be pulling the motor in the near future, as I am swapping everything to a new frame, my question is..
Can i just remove the oil pan and replace the timing cover without disturbing the headgasket?

If I cannot, I will probably try jb welding that crack, because other than this small oil leak the motor has excellent compression and runs great.

Egar

i was wondering the same thing, the timing cover butts up againt the head. how does that work during the replacement of the timing cover?

its much easier to change the timing cover if you take either the oil pan OR the head off,its sandwiched in between and is very difficult to do with both installed.i highly recommend NOT trying to cram it in between because you will damage either the head gasket or the oil pan gasket and youll get to do this all over again...trust me!

angrybob

^^^ what he said.

You have to remove the head OR the oil pan to properly replace the timing cover. It is not necessary to remove them both to do the job properly. If you go the oil pan route, I have done it without removing the front diff...just lower it a bit. Getting the oil pan off and on is a little bit of a PITA, but it can be done.

Best way though is to remove the diff so you have a clear shot at mating the oil pan to the block.

Egar

well ....threw some jb weld on the cracked timing cover. will let it cure and see how it looks in the morning.
