i've been looking for the sorce of noise for the last month, thought it was the cracked exhaust manaifold, still not sure if it wasn't part of it, any way today i put it on blocks had the wife get in, put it in drive with foot on brake and gave it some gas, got under neath with a rubber hose and checked all over, o, i should have also added that when i cruise theres no pr;oblem, but when i hit the gas under a load is when i hear all these noises, so getting back under neath, i found where 99% oif the noise comes from, touching the oil pan by the rear seal it sounds like a spun bearing, anyone have any other ideas?????????, thanks jerry
If it's a knocking sound and it's only under load
it most likely a rod bearing. How is the oil pressure?
