Would anybody know the cold valve clearances for a 1990 pulsar motor? My buddy just built a turboed pulsar and said it ran fine than had a faint he said kinda knock or clicking like the shield between the tranny and block was tapping. He thinks its a rod knock but the sound didn't get any quieter as they pulled the plug wires. Anybody want to venture a guess before we spend a bunch of time and money ripping apart a clean motor with 30,000 on it
