Question: I have a 2004 Chevy Impala LS with a 3800 6 cylinder Engine. It has 76000
miles on it and the check engine light was on.
My mechanic told me that my radiator was never flushed and oil was mixing in with the
radiator fluid. (Sounds to me like I had a bad head gasket). The repairs along with a
serpentine belt replacement cost me over $1100 to get repaired.
I started hearing a whining sound and I thought there was a bad bearing on the belt
tension guide. The engine light comes back on two weeks later and it $625 to fix the
EGR valve with an oil change. I asked them to check on the whining noise and the
mechanic showed me was whenever the oil cap is removed, with the engine running,
the whining stops. Says he’s never seen anything like that in the 20 years he’s been
an ASE mechanic. Says I need some valve work done and that’s going to cost more.
After paying $1800 into repairs, with more to come. Is this common for the 2004
Impala LS or is the mechanic looking to finance his second vacation home? Any
suggestions would be greatly appreciated.

Answer: What repairs were done for the first $1100. This sounds like
a problem one of my Tech's has seen. Was there something done
with intake manifold of gaskets?

Answer: OK. Then I have the answer as to why the engine is making
that sound, and when removing the oil cap it stops. Your engine is
also burning oil. This is not a valve train problem, DO NOT have him
take the engine apart !. The mechanic that did the intake work
messed up. He forgot to put in the PCV valve, or forgot an O' ring
on the PCV valve. This is the reason for your problem. See this link
for location of 3800 PCV Valve.
