Default Re: Engine knock

To de-carbon an engine, you might try Seafoam. Worked well for me so far.

However, the knocking you're hearing may be due to worn rod/main bearings, or perhaps excessive piston to wall clearance. Not uncommon for older engines with 100K+ on the clock.

How's the oil pressure?
