A knock is usually a bad rod bearing on the crankshaft.

You just bought it? Doh!

Yea I just bought the car thinking it was a quick fix not really a car guy just needed something to get back n forth from work... Just need to get this fixed


Alright, have a mechanic diagnose the noise. Could be engine related like Rowe said, could be something loose under the hood, like exhaust. No way for us to tell from where we sit. Good Luck!

Thank u

Well its a piston and bearings could that be fixed or would it be better to buy a motor


All depends if the crank journal is still good, and no scoring in the cylinder wall, or walls. If they are not, rebuild or look for a new motor.
