[QUOTE="greg brillus, post: 119689, member: 597"] Ok so what causes a Vincent to wet sump......?........ do we all think the oil pumps are that worn out........My findings are more along the lines of damage to the pump sleeve bore, this causing oil to bypass the outside of the pump. Of course to actually measure the wear on the pressure side of the pump is not that easy, it can't be from the scavenge side.......careless disassembly and reassembly, nicks and burrs on the sleeve when it is removed or damage from the crank being removed with the pump worm still on the mainshaft and clips the sleeve on it's way out.......... Any damage to the sleeve if not removed first will damage the sleeve housing when it is removed. Don't mean to change the thread, but this is the cause of the thread as it were....... Any thoughts.
