random knock
I have a random knocking sound coming from the front of my engine. Only hear it at 1000 rpms or less. It is not a steady sound and sounds like something bumping around but can't find anything. Oil pressure is 30 lbs. at 1000 rpms and 65-70 lbs. at 2500 to 3000 rpms.
Looking for suggestions on what to look for.
