That is sad to hear. I was doing a leak down on one of my cylinders which showed 20%. I disconnected the air line then plugged it back in, heard a little pop and now it was at 2%. This happen again on another cylinder. I drained the break in oil and cut open the filter. I did not see any thing plugging the filter but on one of the runs, the oil pressure dropped to 30 at idle with the break in oil. I poured 2 quarts of 5-20w mineral oil in and let it flush out the pan. I sprayed each cylinder with Marvel Mystery oil in hopes it would loosen up the sticky rings. Had nothing to lose at this point. Installed new filter and Lucas 10-40 semi-synthetic race oil and started the engine, ran to 140 degree water temp. The blow by was significantly reduced. Have not checked the lead down yet since I do not think the engine if fully broken in. Don't have much fuel.
