Recently, trying to isolate an oiling problem I backed out an
oil plug from the main galley towards the rear of the valley and then primed the motor. I had SO much
oil coming out that it shot over the fender! It happend so fast I didn't even look at the gauge but there is no way I was registering much at all. The difference is this is an FE but from what I've heard from a few knowedgable folks is that it would be extremely noticable if a galley plug came out. You'll still move plenty of volume but at little/no pressure.
