Timing chain cover
#1
So I have had a leak in my timing chain cover for quite some time. I have been thinking about patching it up. But a friend suggested it might be a bad ideas because he doesn't think oil should be circulating in the timing chain cover.
Is he correct I'm assuming that oil should not be in the timing chain area, and plugging it (with JB weld) will just cause a buildup of oil in the timing chain area that shouldn't be there?

And how tough/expensive is it to replace to o-rings?

That's how the chain stays lubed! Yes you are suppose to have oil in there. Otherwise that chain would make a lot of noise!! Think about it...metal sprocket...metal chain..two metal creating friction at high rate of speed....oil is needed otherwise you are talking complete melt down.

JB weld has its place. Cracks in large castings is a good one. JB weld is no substitute for gaskets and o-rings though.
The o-rings mentioned in a previous post are for pressurized oil between the filter, pump, and block. The timing cover doesnt use a gasket, jusy rtv. Fix this right.

Thanks for the help. Sorry for being a d1ck

Doing so will render your engine disposable. Also leaking 4 inches above your pressure sensor is indicative of a bad o-ring. Sealing the outside with quick steel will still allow pressure to leak internally. If you don't replace your o-rings you will lose pressure and kill your bearings.

I can't seem to be able to post a pic in the forum. But look at my profile and there is a pic of exactly where the leak is. Let me know if this helps. If someone can copy the picture into here it would be great!

the only way to know is to open it up and replace. i've had a rattle in my engine for 8 years and i just make sure the oil level is ok and add bg moa to help the oil viscosity and help keep the engine lubed. they've told me 1,800 to 2,000 for timing chain water pump job and i can't see spending that kind of scratch as long as she still quiets down after warm up.

Only the timing chain tensioners might need replacing on a reasonably maintained VQ.
