In my '76 R 600, there is a hydraulic lifter type barrel as part of the rocker arm (possibly an engine brake device?). I was wondering what is the adjustment procedure. If I leave the usual tappet gap, the truck won't hardly run. I tightened them down a ways, and it seems to run okay, but I've got some valve train noise.

Did an inframe on a 1976 R-600 (maxidyne engine, ENDT 676). The old turbo was pretty tired, but put it back on to wring a little more life out of it. The turbo immediately started pushing A LOT of oil out the exhaust side; like a gallon an hour; it smoked like it too. Put on a re-built turbo, and immediately it has the same problem. ??? The oil return from the turbo is free and clear; oil pressure is as it was before the rebuild; otherwise the trucks runs good.
