Compression Test Results

My thinking is that 70 p.s.i. would be adequate to get an idea of where your leak is. The one thing that concerns me is that you had a lobe go flat on your cam. If it occurred in a short period of time then it put a lot of metal into the engine. I think it would be a wise to take your oil filter off, cut it open, and inspect it. If the filter is relatively clean then you are good. If you find metal in there then you will have to tear it down and clean it. If you don't have access to a filter cutter then contact someone who can cut it open for you. Most circle track guys do this as a preventative measure and could help you inspect it.
