There’s a very noticeable noise coming from the engine. It’s a combination of
squealing, rubbing, clicking, chattering…I took the timing belt cover off,
started the engine and concentrated on timing belt, serpentine belt,
and the pulleys and rollers that go with them. I don’t see anything
out of ordinary. Also, both belts are in good shape, about 2 years old,
or 15,000 miles. Noise appears strongest under the intake manifold,
front of the engine. It almost sounds like the starter is partly still engaged
into flywheel, but I very much doubt that. Car always had good maintenance,
good fluids, etc. Car has enough oil, and coolant. It has me quite concerned…
Every now and then, noise will completely disappear, but will return.
