hi all
i,ve been told that before i start my rv8 engine for the first time after a small overhaul the oil pump will require priming. to do this it needs to be packed with vaseline. what i need to know is:- will i have to remove the pump from the engine if so how do i do this? will any bits and pieces fall out once its removed? do i need to prevent any vas entering the filter, how much vaseline do i pack in? and finally is there a nack to replacing the pump so that it goes back together as it should? sorry this seems a bit long winded and drawn out but i want to do this right, and avoid any major cock ups!!

The manual for the serp engine suggests :
1. Lubricate rotors, oil pump drive gear, cover plate and housing with engine oil.
Others here have also suggested filling filter and other oil openings (remove bolts above filter with oil) .. should not be too much of an issue as this pump is self priming - where as the oil style pump (pre serp) was not.

Easiest way to do it is find the oilway that comes up from the pump to the oil filter. This will be the hole to the side of the central thread the filter screws onto on most engines. Pour oil into that with a plastic tube and a funnel and turn the engine over backwards on the crank pulley bolt. The pump should now suck the oil into itself and be fully primed.

Turning the car upside down is not very easy though
sorry couldn't resist
You need to make a plastic cover that blots on in place of the filter to do this, just drill out a hole for a pipe to feed the oil in.I've tried all sorts of ways, and found the easiest by far is an air operated syphon to suck out of the oil pressure switch thread (IMHO), drill operated pumps can do a similar job (but they take much longer). I suppose it is arguable that the suction at that point will also pull any assembly / stale oil in the block galleries out, but a quick spin on the starter should prime the rest of the block if you are worried I would have thought.

just use engine oil
