Yes, loose converter bolts sound a lot like a failed rod bearing.
Loose converter bolts or a cracked pressure plate.
Loose timing chain? Loose heat shield on catalytic converter?
loose or missing torque converter bolt to the flywheel
If you have an automatic transmission, check or have the tourque converter bolts for tightness. I almost junked and engine due to noise under load and it was loose torque converter bolts. It sounds like enigine knocking.
If the torque converter is loose it can do alot of damage to the transmission too. My ex- had to replace the transmission because the bolts were not put in correctly when someone else had changed something out. He had to put in a new transmission and torque converter. If it is running too rough you may have to change it all out. Check the bolts first to make sure everything is tight. If it is then you'll probably need new trany and torque converter.
A hole in the muffler would cause a knocking sound in your muffler. A loose exhaust pipe can also cause a knocking noise.
You probably have two problems. The first one being a faulty oil pressure switch that causes the oil pressure to give a false high reading. The knocking problem could be caused by worn main bearings or worn rod bearings. I have also experienced knocking sounds caused by a worn timing chain and/or a loose torque converter. Hope this helps you.
A knocking noise from a transmission can indicate several issues, such as worn or damaged internal components, low transmission fluid levels, or a failing torque converter. It may also arise from loose mounts or misalignment within the transmission system. If you're experiencing this noise, it's advisable to have a professional inspect the transmission to diagnose and address the problem before it leads to more severe damage.
low oil and a loose piston skirt
Remove the starter and the dust shield. Remove the four bolts (spaced every 90 degrees around the flywheel) and then the torque converter will be loose.
If there is nothing loose rattling around inside and the transmission fluid is clean and the surface where the seal rides hasn't worn down, the torque converter MIGHT be ok to use. You're taking a gamble and you'll have to decide if it's worth the risk. I'd rather spend a couple hundred on torque converter now, then grand on the transmission when the converter fails.
You may have a loose rod or loose roller rocker
