Common Engine Oil Pump FAQ

How do I know if my 4M1011 oil pump is failing?

Look for low oil pressure readings on your dash gauge, unusual ticking or clattering noises from the valve train, or high oil temperatures. If these occur, immediate inspection is required to prevent engine seizure.

What should I do during an engine rebuild?

Always replace the oil pump as a precaution during an overhaul. Replacing it with a 4M-1011 unit ensures that your new pistons and bearings receive adequate lubrication from the very first start.
