Chain making noise !!!!!
 

Well took my 89 911 3.2 to wrench today and got some bad news .
The Good
Starts up perfect , idles fine , runs strong .

The Bad
after complete warm up the engine has an intermediate rattle under load , left bank area . no power loss .

When cold no rattle at all .

He is not entirely sure that the chain is the problem .
He has indicated to me that is also could be a valve or valve guides since I am consuming 1 qt per 400 miles .
He says that he does not do top ends on a car that has 185k on the clock . Valve guides were replaced at 90 k

He reccomended TRE in N. Hollywood for another opinion before I .
He said they would probably do a top end at a reasonable price .

Any ideas without opening up the engine what this could be and is it time to park or fix ??

I would appreciate all imput .


1989 911 3.2

Sounds like valve guides. Maybe an adjustment will get you another 1000 miles or so, but at 1 qt per 400 you are right at the brink of a complete rebuild. TRE is a great shop BTW.

400 miles per quart not 100

I changed it - and yes, 400 per qt is where I decided to take my engine down for a rebuild. Didn't want to run the risk of overheating then dropping a valve.
