1998 Merc Gen VI 7.4
I have my engine half disassembled and I would like to do a compression test on it before totally re-assembling. But the Merc Manual says I shouldn't rotate the engine w. the distributor out. Is this solely because it doubles as an oil pump? What if I used one of those oil priming tools with a drill? If I use the tool, can I disregard that warning?
