I brought my car into a mechanic earlier today because of a clinking noise in the engine. He called and said that my timing chain was bad and would need to be replaced. I found the article at http://www.nissanforums.com/b14-95-...tructions-upper-timing-chain.html#post1229303 about simply replacing the timing chain tensioner. However, after picking up my car an hour ago, I read the full details on the invoice, which reads as follows:
"During the oil change it was found that the engine has noise coming from the timing chain. The timing chain would need to be replaced to correct the problem.
It was also found that crankcase pressure is higher than normal. This indicates that cylinder combustion pressure is bleeding into the crankcase. Engine would have to be replaced to fix problem."
Should I even try to do the upper tensioner? The car has only had two owners: me and my mom. It's got 120,000 miles on it. I've read about how the chain is supposed to be a lifetime part if taken care of, so maybe the tensioner will fix the noise. However, based on the crankcase pressure comment, I'm curious if I should just invest in a new car. I need a new control arm, brakes, and body work and all of this combined is slightly overwhelming me.
Thanks for any input. I have no problem trying out the tensioner replacement, but it seems futile if the engine pressure is all screwed up anyways...
