1987 regal 231 na knocking when warm

[slimone757]

please help me...

ok so here is the run down. i have rebuild the bottom end and replaced crank. well the motor was not primed properly so i ended up pulling the motor and did a complete rebuild.

the machine shop is reputable so i am not sure where to point the finger. put everything back and primed the pump. i am at 80lbs at startup and 20lbs on warm. i know this is low but not really for this motor.

i have replaced everything possible and still once the motor warms up i hear a knock. the knock sounds to be coming from the passenger lower end.

any thoughts or ideas, if i spend any more money i could have bought a grand national. help!!!

thanks

Does the oil psi bounce around at all at idle? 20 is good at idle. Make sure the trque converter bolts are tight.
