Have a 1655 D I've done a complete rebuild on. Everything new on cyl head. Has proper specs on valve protrusion. New sleeves and pistons. One piece pin bushings. 12pt rod bolts. New rod and main bearings.Injection pump rebuilt and new injectors. Bled fuel lines and it started quickly and easily. Let it run at about 1000rpm and checked everything out. Started to increase rpm's And I get a rattle at 1200 rpm's. Rechecked valve settings, checked pump timing, Injectors checked. No change. Pulled head off and the machinist thinks no.2 piston is hitting the head. So where do I go from here? Wonder if a OEM head gasket would be thicker than the aftermarket one.
