Hello,
Kinda stumped with my 84 C20. I had the original motor lodge a rod or two. stopped the motor dead. prior to this issue i noticed the oil pressure wasnt consistent and tended to be kinda low. never electrically irratic but it was run low. at 40-60(after being fully warmed) would hang around 30-40 psi but coming to a stop or at idle would hang around 10-15 psi. i swapped in another 350 and it is having a similiar problem only a little more severe. it drops off the oil gauge at stop now. at idle it sits between 9-12 psi. and seems to respond better under normal driving conditions, sitting somewhere around 40-45 usually. there is some "rapping/ticking/slapping" that sounds to me like valves but at idle sounds like rod knock a little. doesnt do the "rod knock" all the time just after a 30 minute drive. and only at idle. the other sound does it if i hold a constant rpm/speed. any ideas?
Thanks for your time.
