My student w/ the 292 is getting ready to fire his 292 on the test stand, we built an oil pump primer for it and he set to work spinning it with a drill. After several minutes we still have nothing, no oil pressure on the gauge (none in the tube leading to the gauge), no oil to rockers arms, nothing. Pull the bottom off the oil pump and the primer is spinning the gears in the pump, there is oil in the pan (shows good on the dip stick??). I am thinking something might be plugging up the pickup?? Any other ideas, do we just need to prime it for a REAL long time??? thanks-
