Message	So, I have come down to we let the vehicle sit for about four days. Then I tested the compression when cold, I got like 40 PSI on the passenger side, and 80 on the drivers side. Not good. We did a leakdown test and I could only get pressure above 100% leakage on two cylinders on the drivers side. Engine rebuilt about 12,000 miles ago. We aren't sure what the issue is because the vehicle runs great when it gets to temp. But we did take off the valve covers, made sure the cams are all in time. Heads come off tomorrow to see if there's bent valves or a crack or what. Sad to see but at least I'll have some sort of answer soon. Thanks for all that have helped so far.
