So a car is brought to me with a motor that was just rebuilt and has no oil pressure. Pull out the motor found the problem and put it back in. Perfect oil pressure, I let it idle for about 30 min to get all air out of coolant system and while i clean up the garage. Still perfect. Go for a test drive and it starts knocking REAL bad. Get back check rockers, all tight. Pull the motor yesterday and one rod cap is about halfway off. The rest are only finger tight.
WOW, just WOW.
