Good Afternoon, Mark. From my years of working on engines, it sounds
like the 3 camshaft gear bolts are loose. They can be tightened by
removing the oil pump, but the holes in the cam gear will be
enlongated. You now have aluminum particles in the crankcase, which
for us airplane folks, is a NO GO.
I believe Mark Jones has the best reason for the strange engine (or there
about) sounds. You get an extra root beer this fall.

Best guess is a spun main bearing, but even I would be surprised if that's what it turns out to be. Only way to find out is to tear it down. Might as well get to it. In 3 or 4 hours time, you'll have the answer and a game plan to repair it.--Sent from my Android phone with GMX Mail. Please
