The area under the gland nut was machined flat; the down-sized picture does do justice for the excellent machine work done on this Revmaster casting. I just did not have the nut tight enough to compress the fiber washer to seal against the threads on the adjustment screw. The nut also acts as a jam nut to lock the screw. If the machine screw backed out, that would ruin your whole day and your smoke system would not last very long either.
Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA ------------------------------------------------------------- Found and fixed another oil leak on my 2180 VW. I had replaced the external oil cooler from Great planes and installed the Revmaster oil cooler and pump. The leak was on the Revmaster oil pump housing; the oil pressure regulator adjustment screw has a gland nut to lock the adjustment screw in place. I tightened the gland nut to squeeze the fiber washer a little tighter. This fixed leak number 8; hopefully no more oil smoke and drips. In fairness to Great plains and Revmaster, all of the oil leaks have been due to my installation errors.
