Smoking after running

[MowinDad1]

So I just purchased a used 2001 48" Zero Turn with the Kawasaki motor. I ran it for the first time today and it starts, runs, idles, and cuts. My issue was when I shut it down I noticed oil smoke coming from the motor. The previous owner broke the motor / fan stroud so I can see down into seeing around the jug of the piston. It seems to have some dirt and oil caked up on it. But nothing looks like it was freshly leaked.
I'm wonding if anyone can give me some suggestions as to what the issue could be. I'm wondering if I'm going to looking at a big repair soon or do I just need to let it burn off and not worry about it other than keeping the oil level topped off.

It's very important that the airflow over the engine is not reduced and that the cooling fins remain clean.

Take off that broken fan housing, clean off the cylinder(s) and replace that broken fan housing with a good one. AT LEAST once a year remove the fan housing and clean the engine.

What are areas that I should look at for an oil leak once I get the shroud off?

Look at every nook & cranny as you clean the engine.. The engine cover (Blower housing) is easy removal,

And the packed in oil crud will cause that to overheat, as well as that broken housing.

I ordered a new housing and I plan to clean the whole motor off to find the source of the oil. Thanks for the advice. Should I use brake cleaner and a brush or the like when the motor is cold?

I clean them cold. Washing off engine cleaner with a water hose, could cause too quick of a temp difference & damage it..

In fact I don't really like even using a water hose.

Most brake cleaner is pretty harsh stuff, removes paint even. I like to use some stuff called Purple Cleaner, does a good job, washes off easy, cheap by the gallon. Probably some other cleaners like this too. Old school gunk is pretty good, mixture of kerosene and soap but drive belts won't like it.

Compressed air works good for anything that isn't wet.

True enough..

Yep that'll stop the engine overheating from poor airflow for sure!
