Oil Leak From Chain Tensioner

Recommended Posts

Hi All,

There appears to be a weeping Oil leak from the chain tensioner, the car has done 105K and I can only assume its the original part. 

Should I just replace the o-ring or is there any benefit in fitting a new tensioner assembly?    

Cheers.

I have the same thing, replaced the o ring as well as the rocker cover gasket but still the same. I think it's coming from the timing chain cover and as far as I know it's an engine out job to fix, been told it's not worth the hassle on such an old car so just keep an eye on it.

Did the rocker cover gasket just over a year ago, its all dry up there.

I'll have a closer look to see if its coming from the chain cover. The bottom bolt on the tensioner was wet so I assumed its was leaking there, I'll change the o ring, and some rtv on the outer flange.

I take it no need to drain engine Oil to replace the o ring on the tensioner? Anything else I should be aware of?

No no drainage needed, when removing tensioner you will need to reset it before re installing it, vids in YouTube for that.

Finaly manage to change the oring as the mess behind the engine got to me. Had to drop the one side of belt idler arm to make it easier to work on, didn't fancy getting under the car.

I didn't feel comfortable using sealent around the oring...will see how it holds without it.

Cleaned around the area so I can keep an eye on it.

How did it evolve after a few years? No more leak?

I notices this area is dirty on my car. Might start to get leaking just a little bit. If I ever have to change the o ring, I wonder if it would make sense to change the tensioner... Price difference isn't an issue as the part is quite cheap, and it wouldn't take more time to change the tensioner.

My question is: does the original tensioner do its job fine for the life of the car, or does it fail after a while in some cases (not enough tension on the chain, causing trouble to the engine)?

Thanks!

The o - ring should be just fine to replace on its own without the need of a new tensioner.

When I had mine done though I resealed the Oil sump and replaced both timing cover gaskets as well.

I've not lost a drop of Oil since.

Hey nginx,

Sorry for the late reply.

Mine is still leaking after replacing the o-ring, I thought the o-ring should be more snug but its not.

What I did notice though, when the Oil drops to certain level its slows/stops, so I guess when it goes below the tensioner level?

Either that or the leak is else where, its not the rocker cover, could be the top of the chain cover....couldnt be bothered anymore so left it.
