I pressure tested the motor after I flushed some of the oily water out. I pumped it up to 15lbs, Watched the gauge as it leaked down over a period of only a few minutes. I did the test with the plugs out, same result, could see the needle slowly move away from 15lbs. I put four spark plugs in the passenger side head, still leaked down. I put four in the drivers side head, still leaked down. I put some "Blue Devil" Radiator cleaner with oil remover, ran the motor for 20 minutes. Watched the flow through the open radiator neck, and water flowed smoothly, temp gauge only moved to the first mark. When it cools down, I will drain the cleaner out, refill the water, and conduct the Leak Down test again. A little history now. When I installed the motor I used the FelPro gasket set the original owner purchased in 1998. It came with the short block he had rebuilt and stored, until I purchased the car in September, 2021. The head gaskets are metal, with the blue sealant around each cylinder hole. The original owner installed new rings, rod and main bearings. It was not bored oversize. I found no evidence of cracks to the naked eye, and he indicated the car 99000 miles, and he decided to do the rings and bearings. I rebuilt the heads, and they were free from any cracks. I installed a Melling cam and lifter set in May, the cam was properly "broken in", and the motor ran strong for a few days, but developed a soft cam lobe. At that time, there was no oil present in the cooling system. A few weeks ago I installed a "Howards" cam and lifter set, broke in the motor, and it ran strong. Except I discovered the oil in coolant now. That's the story of how I am where I am today. Phil
