Is there a certain part of the sump it happens with regularity?
And not on the Bellagio?!?
Best fix? A better gasket material maybe? At least checking that both castings are dead flat by lapping on a true surface. Thank's for the heads up Pete.
Pete are you saying, this just happens. It gets blown out. Or is it a case of people dropping the pan for whatever reason and not putting it back right ? appreciate all the advice and the pic's you post up when you do work
Pete, when you say the 'sump spacer' what are you referring to? Looking at my Norge I see a sump and a block, with no spacer - except perhaps the following. Looking at the parts diagram, I see this: Are you describing the flange (#25) as a 'spacer', and is the gasket in question the one labeled #24? If so, for everyone's convenience, the part number for this gasket is GU01003651.
I'm not going to but... is there enough meat in the casting to bore and tap for a securing bolt up from underneath to "clamp" the faces together locally? Naturally a spot face for the bolthead or all too damn much ?
. . . Pete mentioned in the past about an O ring in the pickup strainer assembly that could become displaced and get "sucked into" the circuit, causing problems downstream . . .
