Just finished putting together the JK after replacing all the timing chains, tensioners, oil pump and water pump. Started up fine with a few electrical codes (cooling fan wouldn’t run, bad ground). Idled fine and smooth, rev’d the engine up to 2500-3000 and threw the following codes, followed by a pretty decent engine knock. Won’t idle smoothly anymore, knocks pretty hard. Shut it down quickly after that. P0394 - Bank 2 Camshaft Position Sensor 2/2 Circuit Intermittent P0019 - Camshaft... Timing issue after replacing chain/tensioner assembly
