my daughter, away at school, had the oil changed in her 1990 Camaro
305 tbi, auto. The next morning on start up the engine made a loud
clanking-cracking noise, as best as she can describe, louder in
reverse, lower in drive and lower still in park,but a
clanking-cranking sound.. the noise goes away when the engine warms.
The service center denies any wrong doing, naturally, and she took it
another service shop and without the engine temp cold they could not
find the problem but did find the engine oil was way over filled. This
extra oil was removed. There is no obvious damage to the exhaust pipes
that can be easily seen. I will not be able to travel for a while and
was really curious as to what damage was done by the new trainee at
the service center. What can be damaged by overfilling the oil (
double amount on the stick) do?. The fact that the noise changes in
different gear makes me believe the exhaust is dislodged but a midas
muffler shop could not find the problem . The manual shows a E.F.E.
valve (early fuel evaparator) in the left side engine area where the
noise appears to be coming from. Can this be damaged?
