I have a pair of Crusader 270's circa 1983 with 1400 hrs. On cold start up, the port engine has a squeal or whine that goes away as the RPM comes up. At first I thought it was a belt, changed those, the raw water pump, changed that, the alternator, took that off and had it tested fine, changed cap and rotor, (has been updated to EST ignition years ago) to and still i have this squeal. It does sound a lot like a bearing running dry. I am running DELO 400 15W40 oil and change it annually at about 60 - 75 HRS.
Now I am thinking this might be oil pressure related (as it goes away and does not happen on a restart) but am wondering if any of you might have some ideas of what to check next.
Appreciate all comments and thanks in advance.
