I assume the engine is an M-18 Kohler. The first couple of thing to check are: First be sure you have not over filled the engine with oil. Second, Be sure the oil fill hole and dip stick are sealing well so outside air can not enter the crankcase. If both of these check out, your engine likely has to much blow-by and needs rebuilt.
I have done several of the Kohler KT-17's. The main difference in the two engines is the KT-17 are battery ignition and the M-18 is an electronic flywheel magneto. The M-18 has a full flow oiling system with oil filter. Early Kt-17's were NOT full flow oil system. The later Series II KT-17 were full flow oiling systems. Not all Series II were set-up for an oil filter. The last KT-17 I did was for Dad. I took a plain Kt-17 case and converted it to a Series II. When I do a Early KT-17 that is not a full flow system, I drill a couple of extra oiling hole in the rod so they will oil better.

Oil level is perfect & dipstick is in place, I heard that m-18 have some reed valves of some type for crankcase, if these break, will this cause this concern? but where the Heck are these at ? Commander Engine

If it is a Commander engine FORGET EVERYTHING I posted. The engine in you CC is a Over Head Valve engine. I have NOT turn a wrench on one of them. I have on an earlier Kohler OHV. If this was a Briggs OHV, I would say you may have a partially blown head gasket the is pressurizing the crankcase causing your oil blowing problem. Briggs had a problem with this.
I do not know how much of a WRENCH you are. You might try holding each cylinder at TDC on the compression stroke. Then pressurize each cylinder with compressed air to see it you have a leak into the crankcase. If you try to do this be sure to firmly hold the crank from turning. DO NOT do this with your hands! you need to bolt it solid some way.

I had a very similar problem with my Tecumseh HMSK-80
It turns out that the oil was getting slung everywhere because of two things, the plastic oil slinger gear (with the metal flyweight inserts) needed to be replaced, and the governor was not set right.

Maybe the same is wrong with yours, I am not familiar with the engine you have,

Good luck,

Chris

If it is a twin cylinder, check the compression on both sides of the engine, you will probably find that one side is considerbly lower than the other. The one with the lower compression has a blown head gasket. These command engines were known for this. Replace both head gaskets, not just the one that needs it. Also it is recommended to replace the head bolts when you do a head gasket. The difference in compression would be approx 35psi +/-...

Bd, I don't know about your engine but on the older K series Kohler's the reed valve is under the valve cover.

Compression test results, both banks are the same, so I say this kohler has had a hard live, because are other cub of same type has had great care & still doesnt use or leak a drop of oil between maintance times, with more hrs then the one with this concern.That proves that low ash oil from I H works!!!!!!

The reed valve is under the cover where your breather hose enters the block. top center
