High pitched squeal from inside engine
For the last week, there is a constant high pitched squeal coming from inside my engine, at first it seemed to come from the air filter but it gets very loud when I remove the oil fill cap, so it's coming from inside the valve cover or engine. My regular mechanix tought of an air leak from the intake, so he did a smoke leak test but nothing showed, no vacuum leak, oil is fine, drives OK too. Today I started the engine cold and the squeal was not there, shut the engine, restarted and it was back again. Any ideas or suggestion ? 06 with 29K miles
