...noise while climbing hills? 1995 Chevy 350 (2 Bolt) stock w/ 305 heads. Replaced ign coil,cap,rotor,plugs,wires, all vac hoses, and cleaned EGR valve and port. Plus Engine Light keeps returning with EGR Code..?
The top end has made noise before the oil pressure dropped and the bottom end started just recent. The bottom end only makes noise under load above 2000 RPM, Would a worn distributor gear have anything to do with my issue's?
