Timing cover

Post by loveMy850 » Mon Sep 11, 2017 9:20 pm

MY COVER PEALING OFF IN THE LOWER CORNER, my oil leaks getting worse, I want to have the parts to take to his shop, I had the water pump along with this job done awhile back, I wasnt happy first thing I noticed was that the timing cover was loose,, but I did get the pump and timing done, I think he could have done a better job but none the less the pumps done, just to be safe besides the cam seal, and cover what else do I need? Im hesitant about driving her very much when I found problem, should I get a belt to be safe.help... THANKS

Are you sure you don't have a bad crank seal? Happen to have a picture of everything?

I'm not familiar with you particular model but most vehicles you'd have to remove at the very least the serpentine belt tensioner and potentially the harmonic balancer.

Is that difficult,is there a certain degree the tensioner has to be adjusted? I think is is just the tension belt

This makes no sense- cover split all the way up, a bad oil leak, etc., etc...now tensioners.
To replace just the cover, no need to deal with any tensioner, belt, etc. But your issues run deeper. If you have a bad oil leak it's under that cover. You probably need cam seals. The crank is at the bottom. You'll have to take the cover off to verify which seal is leaking. It's best to fix that... yes- the timing belt has to come off to do that. Yes, I would get a replacement belt as it's most likely soaked in oil too.

Thanks, it's funny I mean it's not a real bad leak very little oil, and I had the seals replaced in 06, but that cover is really strange indeed, I don't lose a lot of oil, that's what's bothering me, something like this I have to take to the shop, That's what a bummer of green?, Know what I mean. It's just little drips under the passenger side, it looked to me about a year back it was coming out of that case, I don't know perhaps bite the bullet and take it to the shop, ya think?

Take a picture so we can see what we are trying to help you with. I can't follow what you are talking about or what the issue is.

The timing covers do become warped and brittle with age, and if the front cover 10mm bolt is over tightened it will crack the front cover, or if the wrong bolt is used. The cover bolt has a shoulder on it to try to prevent that happening.

As to what you need to do to replace the cover, the timing belt has to come off to remove the rear top section which fits behind the cam gears/pulleys. Can't recall if the lower one needs the harmonic balancer to be removed, but I think it does. Are the rear parts actually broken, or is it just the front cover?
