Yeah, I'll try and run it on the trailer and bring it up to temperature then re-run the compression test tomorrow. I had a member on another fourm mention trying to adjust my hydraulic lifters like solid lifters to make sure there was nothing holding the valves open. If my results are still off I'll try that adjustment and re-checkkng to see if that may be the problem.

I'll run my checks "today", since it is already Sunday, and post the results.

Thanks again!

bent valves will hold them off the seat .hyd lifters will not hold the valves off the seat for very long till you wipe out the cam . you would have to run the push rod down in the lifter past the valving .so you could very well end up with burnt up valves or cup vavles and a trashed cam
