What should I do if I can't get the knocking to stop?

Community Answer

If your car has a rod knock, chances are are this engine will need very expensive repair or replacement.

Question

My car just started stalling and making a knocking sound. It had no oil, so I topped it off, but it still rattles. Can it be saved?

Community Answer

It's done; it needs a new/rebuilt engine. Your rod bearings and main bearings are probably gone.

Question

How do I fix the knocking completely?

Community Answer

Once an engine starts to knock, the damage is already started. Repair (expensive) at a minimum is about the only recourse.

Question

What would cause a motor to knock one time and not the next time I start it?

Community Answer

Your harmonic balancer may be getting old. It can cause the timing to bounce around. Check your timing with a light.
