| | HELP, Bad Compression/Good Leak Down
I have a misfire on cylinder six (6) and a ticking noise under the hood. Doesn't sound like rod noise. Ran a compression test and cyl. six (6) failed. It is only 90 psi while the other five are 190 psi. Ran a leak down test and it passed. Only 4% and only crankcase noise. No evidence of leaking valves. I can't figure out what would present these two symptoms at the same time.
Anyone got any ideas?
