I've been fighting this stupid oil leak for quite awhile now and can't seem to stop it. :steam:

The oil is leaking on the PS of the Rear valve cover can. It's pretty much pouring out! When I come out of work (after 8 hours) there's about 100cc worth pooled up under the truck.

The gasket appears to be in good shape.

Is there some little trick to setting this gasket or what ????????

oil leaks suck. I traced 3 separate ones down when I bought my truck, glad I took the time to do it. and makes you feel better when it finally stops

Are you sure it is coming from the #6 cover? I have had prob. reusing gaskets when adj. valves. I would say clean the hell out of it with brake clean, run for a bit and ck it, you should be able to narrow it down like that.

I'm pretty certain since it's pouring down the PS rear of the block.

I'm going to clean it off like you suggest and then use some baking powered to try and see where it's actually leaking from.

I'll go buy NEW gaskets as well. :beer

There are also "O" rings that seat under the bolt head.

I have individual gaskets under each of my cans. I replaced them and dried mine right up.

The old one's get hard and brittle is why.
Don't over tighten the new ones.
The neoprene is soft.

And make sure the head surface and gasket are bone dry when you put it together. Oh and make sure the edges don't get folded under when reinstalling the VC as the ones in back are hard to feel/feel.

first I sprayed all the oil covered portions of the engine with engine de greaser, and hot pressure washed all the oil off.. then I went for a drive. found where the oil was coming from. fixed that spot. drove for another week, and more oil kept coming. cleaned engine again. found new spot. fixed it again. the third place was tricky and required me to get the motor spotless and find a tiny little leaky spot in the back side of the timing case.. it was a pain, but She doesnt leak anymore:woot::thumbsup

Use a mirror to carefully inspect the gasket on #6. It may be rolled over a bit. Trying to feel it may not work because the space between #5 and #6 is hard to get at. Don't ask me how I know this.

If it's oil leaking from between the gasket and the head assembly, when you go to replace the gasket, put the valve cover on without the gasket, loosely tighten the valve cover bolt and rock the valve cover.

If it rocks too much and or a large gap can be seen between the valve cover and the head, then you may have to grind out a little of the webbing on the inside of the valve cover, if I remember correctly its' usually the bolt on the rocker assembly that bumps the webbing in the valve cover, (grind down the valve cover, not the bolt). A dremel works best, and remeber to clean out all the shavings, and don't overtighten the valve cover bolt.

I can't remeber exactly what the required torque for the valve cover bolt is but I'm sure someone will comment on that.

The webbing does not have to be ground if everthing involved with head is stock including the cam shaft. The valve cover hold down bolt has a shoulder on it to set the correct pressure on the gasket so torque for it is not important. Just tight enough so it doesn't come loose. I think that the service manual says 18 ft lbs.
