That was the first thing I thought as soon as I saw the pictures--the centrifugal force of the flywheel, it shoots oil everywhere. Rubber shielding lost seal by wearing out due to bearing play. But as mentioned before, it could also be the exhaust manifold gasket. Need to clean it and see at oil leakage with model running but on dyno.
If the engine is now already at its end, many times it is not worthwhile to repair it but to replace it with a new one (I am talking about this kind of inexpensive engines) example this one at definitely affordable prices.

That engine is one of the best I have tested. Buy it with confidence, it tunes and idles super good.
