Has anybody ever had the valley pan on a big block "balloon" if the fiberglassish material pad isn't installed- plugged PCV or?
I've seen quite a few back in the day, I just wonder if it was excess blowby, a plugged PCV, or? Was it common, or did I just see a few more than most...?



To BALLOON up a valley pan ..... is way WAY more than just a plugged-up PCV ..... there are MAJOR piston or piston ring probs going on. The last one I saw was a MH 440 that a guy had gotten out of a JY. The VP was almost "molded" to the bottom of the intake. There was a hole in one of the pistons the size of a quarter !

A plugged-up PCV ? ... you CrAzY CaNaDiAnS !
