Oil pressure relief piston - what if stuck?

[briankeithsmith]

Just a question:

If an oil pressure relief piston stuck in its chamber while the car was being driven, what would the symptoms be that would indicate that the pressure relief pistons were stuck?

Reason I ask, and I may be way off base here, but one of the reasons I rebuilt my engine initially was because I was getting significant amounts of oil out of the crankcase vent, under hard driving, which I assumed probably meant I had a set of busted piston rings. The rings were fine (pistons were in bad shape though), and now that I've learned more through this rebuild process, I was wondering if it might have been that I had an oil pressure relief piston stuck? Any possibility, or would I see different set of symptoms in that instance?

Thanks,

Brian

My questions would be, how would a piston get stuck? How much pressure is on that piston at full RPM? I would imagine that it would take a lot to make the piston stuck based on the pressure being exerted on it?

And I'm interested in what the symptons would be? What damage would be done?
