My Mk3 wet sumps after every ride, so I have to drain crankcase 10-20ozs.
I installed an antisump spring loaded ball check to no avail.
I ride everyday.
Should I open up the excellent running engine and follow forum advice on what and how to fix?
Or install a ball valve?
Sounds like the little anti sump plunger that sits in the timing cover and closes off the oil pump when the engine is shut down is stuck open.
Has anybody found a brand new oil pump that allows wet sumping ?
If yes, what quantity of oil, over what time interval and where & when was it purchased ?
Hi Mylar
Presumably lapping your old pump did not cure the wet sumping?
Yes but if a daily rider is wet sumping then the pump clearances are way too large as well, the oil pressure will be no doubt too low.
