I recently changed my oil
on my Westerbeke
64A. All seemed fine; drained/refilled oil
; replaced Westerbeke Oil Filter
with Sierra equivalent. Started engine
to ensure no leaks
; all still good. But when I rev'd the engine
to put a little pressure on the system (nothing extreme, just up to 1500rpms), the oil filter gasket
gave way, sending oil everywhere.
I shut down the engine, and removed the bad filter. I put another one on; refilled the oil (to the prescribed level) and tried again. SAME result. Anyone have any experience like this? I'm thinking maybe the Sierra filters are at fault (perhaps not really identical in their sealing configuration).
I don't have an "old gasket" remaining in the bracket and the bracket appears to be free from debris or deformity. Kinda at a loss. I have ordered some Westerbeke oil filters to see if a genuine filter will resolve the problem.
But I would love any knowledgeable thoughts about what might cause this or any other insights
