Folks, I got my E28 out last week to get it ready for a run on the weekend. It had a fair bit of oil had seeped into the crankcase (not sure how). Normally I would remove the sump drain plug in those situations - but the E28 doesn't have one. I just ran it until it had blown all the oil out one way or another - but this is not really an environmentally sensitive action.
Anyone got any suggestions on this ?
