Aloha from Hawaii!
Needed some advice on a squealing/vacuum leak type of sound coming from the top half of my engine. It only occurs at low RPM's (~1300-1600), happens after running for a while (*****ing for an hour or more) and it comes and goes (sometimes I won't hear it for long periods). It usually takes a good long while for me to start hearing it, and I never hear it on startup while idling. Once I speed up the RPM's the noise will go away when it's heard only to return again once down to the low rpm's. It's not really a belt squeal and I'm wondering if anybody has had any similar experiences especially with this model engine. I will probably take it in to get looked at but was hoping that it was something minor that I could check on myself or wait until my 100 hour service (engine only has 80 hours).
Mahalo in advance!
