My newly rebuilt 283 Chevy creates so much crankcase pressure that it blasts oil out of both breathers and no small amount. It is for this reason that I have not made more than one pass down the track each week. At first I thought i just didnt have adequate ventilation with only the breather on the intake and a pcv in the back. I added the road tube setup but with a clear 1" flexible hose so I could see if oil went through it much. none. Then, I went to the track and at high RPM my motor lost 2 1/2 quarts of oil in one pass. The 283 feels weak and not like my previous 12 second motors. That may be tuning and carburation, but I cant test this when it pushes that much oil out in a single pass. Does this sound like bad rings o anyone? I am wondering if the rings didnt seat. Kind of reminds me of how a super soaker works. any suggestions?
