Sounds like a timing issue. Maybe a valve train problem. If the valve and the piston hit each other, a piston might be damaged.
Pull the right side valve cover for sure, but I'd also pull the timing cover and inspect the timing @ TDC. Turn the engine by hand using a socket wrench and watch the valves work, look for broken valve springs, missing valve keepers, etc.
Finally, if all that looks ok, do a compression check on each cylinder.
The reason you don't have water and oil mixed is because you haven't blown a head gasket.
