"engine completely rebuilt about 200 hours"
So exactly what was done? to some, complete rebuilt is a seal or two maybe a gasket and spark plugs.
A complete rebuild is oversize pistons/rings, valves/seats ground, or replaced, crank turned new seals/gaskets and ignition components among other things.
I'd clean it up and run a compression check just to see where you are at.
It sounds like you have something seriously wrong to blow that much oil everywhere,---- or you have a blown crank seal and the fan is blowing it about.
The crankcase is not pressurized normally.
As the crank turns it pushes the pistons out into the cylinders simultaneously,
then pulls them back simultaneously, alternating between vacuum and pressure.
In real life you wind up with a little pressure in a worn engine, a new engine has a bit of vacuum, maybe.
It is covered in the service manual and measured with a manometer
Make sure your breather valve is functioning/installed properly and the little orange neoprene sleeve is installed properly over the stud.
Some shops don't know which end of a spark plug screws into the heads.
others are more educated.
Let us know what you find.
