Re: Poor Compression
It was a cool morning, only in the 80's and I made a couple od discoveries with my truck's compression issue. I was able to determine it is the exh. valve leaking as suspected.
I also found that an air hose fitting has the same threads as my spark plug and was able to put it in place of the spark plug, assure that my #1 was TDC with both valves in the closed position. Attached air hose to the fitting and set pressure at about 20 psi.. Air flowed out the exhaust pipe. Poor man's leak check.
I will be finish the job after my iced tea. It's now in the 90's.
