Hydraulic chain tensioner question

[slodave]

Hi!

While removing my engine for a second (unplanned) time, I noticed that there seems to be some oil leaking around the chain tensioner covers. I know what happens when things fail in there, so we don't really need to go there. I did not think to take pictures of the area, but can if needed. Could the gaskets just be leaking? What about the lines that feed the tensioners? Is it an easy task to replace the tensioners? Yikes, I see that tensioners cost $231.00. Man, I really can't afford this right now!!!! But, I guess if they fail, I will have to spend a lot more than that.

Thanks!!

Replace the leaky gasket.

Hmmm.... Can it be that easy and cheap? I can afford to do that. Thanks!!!

fairly easy to replace the o-rings that go between the tensioner and cover plate... a word to the wise... in some "rebuild" kits you get o-rings that are undersized... they may seal ok or not... viton is a good material for that application... you want to feel a good compression as you put the plate on...use a bit of oil or grease on the surfaces .. I'm sorry I now don't have the dimension details.

Dave:
Before you change the gaskets make sure that the 0-rings seal properly.
Get new ones if necessary.
If you get new gaskets, clean the case, and cover, real good.
Then, apply a thin cover of anti-seize lube to both sides of the gaskets before installing.
It's an old trick we use in industrial applications; it means that you never have to clean/scrape the surfaces again to remove parts of the gaskets.

I have decided to put this off for a few months. The area at the bottom of each cover does have oil/dirt around them, but it does not seem very fresh. I have to replace my cat in a few months anyway and I believe I will have more room to get at them. I am also tired of the current project. It has gone on too long and I want my car back. If it looked bad enough or if I had noticed a huge puddle on the ground under them, I would o it now.... I will refer back to this thread, thanks for all the help and ideas!
