Hi all,
If I have issues with my valves not seating correctly, would this cause a faulty compression reading on a test?
The reason for suspecting a valve issue is I'm getting a carbon trace on one side of my spark plug from the electrode to the base and someone mentioned that this could be due to a valve problem not seating correctly.
The interesting thing is though I'm getting this on all cylinders (the carbon trace).
I'm readying a 4.0L head to go on my jeep and wanted to test the engine so as not to put a good head on a suspect engine. The only test I know to determine engine strength is a compression test but if this could be in-accurate due to valve issues then I won't have a valid reading.
Thanks for any suggestions, comments.
Bill
