Just changed the oil, added quart of mmo. New sparks and wires yesterday and a new left upper timing chain tensioner (thought this was the cause of the rattling, good swap anyhow as the previous owner installed the wrong tensioner it seems, flat instead of the tall one). My only guess is lifters, or chain guides. I rev a bit in the video below to demonstrate the change of rate.
