Could be a duff
control ring on the piston which may only be detected by a leak-down test. What measurement are you using when you say 12.5
Hi Madnoel 10
I unscreewed the plugs and conected a compression tester, which in turn said 12.5 (PSI). Well, you could of hit the nail on the head there. When ever the engine is running, i here a small tap like noise from the area in line with that cylinder. Faint, but there!!!. simlar to a plug lead shorting out. Best i do or get a leak down test done..
Thank you very much!!!!!!
