"Said bozo" caused a brief interruption of oil flow to your camshafts

- hopefully he had pre-lubed them well *grin*. I just re-read the FSM with respect to oiling and there is no direct mention of piston lubrication, but it's always been my understanding that they get splash from the crank and rods. FSM states the camshafts' rotation splashes lube on the cam chain rollers and tensioner down the tunnel. As for the 219H chain... I'm surprised you hadn't read some of the many discussions on here about the heavy duty version of the 219 chain being more difficult to get cam timing correct, and the differences in master links as well (can't use one with the other and vice-versa). After some research, I chose to use the 219T chain from DID which is the OEM chain - I'm familiar with the chain, have never had any trouble with them in any way, and the master link is easily staked as design-intended. Just personal preference in some ways but there are a few people here who have tried to use the 219H and had difficulties getting the marks to line up as they expected (I haven't ever tried one so no personal experience here). Some feel it's the diameter of the rollers in the chain, others have suggested it's the side plates' size causing the chain to lay on the rubber damper rings on either side of the sprockets and therefore ride higher in the sprockets (I don't use the rubber damper rings, they just deteriorate and come apart after a while anyway and the slight additional noise supposedly generated without them isn't an issue to me)
