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?

 

From your post that you state along with your friends advice, I would suggest you take the car to a shop and replace the o-rings to stop the oil leak from the timing cover.

 

So the real issue is that oil is leaking into the timing chain area?
And how tough/expensive is it to replace to o-rings?

 

ummmmm, what??

 

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.

 

Ok, cool! Thanks for the response! That's what I thought, but my friend threw me off. Thanks again!

 

So would you say FB weld over the timing chain cover seal is a good alternative fix?

 

 

Yes?

 

Stuff like this is what pisses me off about some of you guys. This forum site is meant to help people and share knowledge. Yet you feel it necessary to mock the person asking the questions.. Look at your username... Grow up..

 

 

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.

 

You need to get laid bro..

 

.....and you need better friends lol.

No oil on a timing chain?


bicycle chain: oil
Motorbike chain: oil
Chainsaw: oil

I mean, wtf

 

Yeah I agree. I think I might be patching it with some quick steal, because I don't have the time to re-Rtv the whole timing chain cover, and I don't wana pay 1000 to have a shop do it.

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!

 

 

I'm having a rattling in my timing chain can it be from not enough oil getting into the timing chain cover or do I need to replace the tensioner

 

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.

 

If it rattles at start up don't worry. If it constantly rattles then you need to take off the small access cover plate and check the tensioners/guides. It's a fun job.

 

If you've been quoted 1800 to 2000 then these guys are talking about replacing the timing chain itself. That should almost never need to happen.

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