The number 4 cylinder was basically a water pump. Water was getting sucked right into the cylinder and out the exhaust. I got a set of remanufactured heads and almost got it back together, should run fine (if that one little shitty spot on the block deck doesn't cause an issue). There was no water at all in the lifter valley, only water was extreme condensation in the valve covers that caused the goo on the underside of the valve covers and some superficial rust on the rockers that came off easy. If the blemish on the block deck seals (and I think it will), looks like I'm going to get more time out of this motor
