New noise I'm trying to sort out. Right from start up. Knock at bottom end. 1997 D1 with a 4.0. Cylinder heads done under 10k miles ago. Definitely bottom end noise. Last year, someone tried to steal the cats which is the welds you see where they patched the cuts. Doesn't get louder on acceleration but it speeds up. Can't tell if it's speeding up at the same rate as the RPM.
Any thoughts?
