Bitter learning curve. Absolutely DONE with carburetors!!!

Have not torn it down, just drove it home tonight when this happened. I checked the oil and the level has not changed, but, when I wipe the dipstick there is clean new oil and a slight film of grey film on the white rag. I'm assuming this is the babbot from the bearings??
Also the oil pressure is low, 5 pounds at idle after warm, 23 at 2k rpms, 32 at 3k rpms.

As inertia says, this grey film can be water/condensation. Not sure how you can say it is not.... grey scum under the valve covers is indeed one of THE common results of a non-working PCV or moisture not getting driven out. It aslo can be brownish.... How does the coolant level look in the radiator? I don't think I have ever seen bearing materials show up on a disptick, even with a temporarily seized crank and another case of totally wiped out and spun main bearings; it all went to the bottom.

Those oil pressure numbers do seem low.... how were the pressures when the engine was breaking in? What weight of oil are you using? FYI, our new engine with 200+ miles on it has no less than 35 psi idling, fully warmed up, with 10W30. The clearances were all in the middle to upper end of spec range. Pump is an HV pump. Any reason to think your oil pressure gauge could be off?

BTW, I would not be driving it at all.... that never makes things like this better.... unless it is carbon'd up plugs.
