Im wondering if I have a knock in the rod or main bearings, Would it be easy to figure out which one it was by dropping the oil pan and looking for visual signs? Someone sugested check each cylinder by taking off spark plug wire, and running it? Thanks, trying to figure out where the knock is coming from, I have narrowed it down to either three things: maind bearings, rod berings, or flex plate?? I posted this earlier: Well when I first rebuilt it it drove fine it did not have that knocking noise, but five days after the rebuild I was going down a hill a big hill and I decieded to coast down it in neutral, so I put it in neutral, after I made it down the hill I put it in drive, and I heard a little pop, well my torque converter went out, So I had to pull the engine again and replace the torque converter, well ever since I had to pull the engine a second time that is when it would make a knocking noise. Is it possible I did not check the flex plate for cracks? Because after I first rebuilt this it did not make that noise, and I have been driving it like this for the last 7000 miles and have not heard change at all so im thinking it probally is not the rod bearings, because driving it that much the rod bearings you would think would start to ware out more? Thanks. |

Plasti-gage is the way to check bearing clearances. Remove the oil pickup tube. Remove one bearing cap at a time. P/N SPGR-1 at most auto parts stores. What were your bearing clearances upon assembly?

You could have an exhaust leak, a noisy lifter, or a broken piston. |

Or a loose rod cap. If it is a loose rod cap and you keep running it, it will eventually jack things up bad. Find the source of the noise quick. |

Well I have been driving the car for 8000 miles since I heard the noise, and it still runs fine? Today I will pull the oil pan off and check the torque converter bolts? Thanks. |
