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...?
It has nothing to do with the pad under the intake. The valley van will ballon if you don't have some type of breather/PCV valve.
I had this happen the first day I broke my engine in. In my excitement, I forgot to install a PCV, and with all the blowby of a newly-rebuilt motor, it popped that valley pan like a piece of popcorn!
When, it happened, I'd thought I thrown a pushrod or something  ...sounded like a gunshot!
