ok guys and gals. Im having cold start issues. When ever i start or restart motor when its cool i get a knocking sound. The knocking sound appears to be coming from bottom end. This happens when motor is revved to 3k rpms/no load and only knocks when its idling down. Now when the engine is completely warmed up it doesnt happen whe i try to duplicate it. What do you guys think?I have only 20k on this set of bearings(standard). I was thinking of going to a larger bearing and drill the oiling holes in it larger for better lubrication. I have a 92 se-r with 8:3:1cr DE Turbo 4 bar program.
