Hi,

The "mechanical" timing is correct. I also adjusted the valves when I put the head in. The "popping" sound that i get when I go to check the compresssion has got me stumped. The "popping" sound has got to be a symptom of the problem. It sounds like "passing gas". I only get it when I am checking the compression. When I just "spin" the engine without the compession test screwed in I hear nothing. The valve work was done when I had the cylinder head pressure checked. I did use a new "factory" head gasket. Could I have gotten a defective head gasket from isuzu????

Is the head gasket the only place where I would get an audible compression loss???? Would a leaking head gasket give me an audible compression leak????

Thanks,

Mike
