Things are taking a turn for the worse again. I pressure tested the intake and it was all okay with the crankcase. No leakage from rocker studs or head bolts. I did decide to do another leak down test with my garbage Harbor Freight tester. My results are all a lot worse than they were in April of 2024. I dont trust the testers accuracy but recorded readings of 20-40% and hearing the escaping pressure through the rings is bad. To make my night even worse I sent my borescope in the holes to look at the pistons and bores. The first 2 are of cylinder 1 the last 2 are 6. Does it look like pre-detonation in cyl 6?

Im so upset but I think I might have my 3rd rebuild in 2 years.
