Coolant in oil

So I have a freshly rebuilt cub and I was wondering if this oil looks good or has coolant in it. ( the oil has not been changed since it was rebuilt a year ago) and probably has 20 hours on itIMG_1906.jpeg
 
Hi,
On my computer the oil looks a normal color, for oil used a short time.
Has the oil level gone up on the dipstick from what it was at first, or has the coolant level gone down.
The head bolts should have non hardening, liquid sealer put on the threads when putting the head on the engine. The bolt holes go into the water jacket, and without sealer coolant can run up the threads, and leak out. :)
 
If it was setting over the winter, it may have picked up a little condensate from the iron block heating and cooling with the ambient temperature. Maybe check the coolant level and hydraulic level to see if there is any contamination in the oil or leakage into the oil. If it has not been turned over for a while, any coolant should be at the bottom of the oil pan by the plug. First thing out would be water or coolant if you loosen the plug. If you are uncomfortable about the oil color you could change it, but I would want to know if there was a reason for it before changing the oil.

It was used about once a week during winter
 
If the Cub was used in cool or cold temperatures, and not fully heated up for some time running, Cubs can get condensation in the engine oil. It can be in the oil filler, dipstick tube, and it can be thick and white there.
 
I think your oil looks quite normal. Because Cubs have no thermostat, they will not reach proper operating temperature in cold weather operation, thus condensation does not get burned away. If you’re using your Cub for plowing snow or hauling fire wood, or whatever, you should cover most of the grill to help it warm up.
 
As Cubfriend suggests, drain a little oil to see if there is any coolant. Use a glass jar and let it set for a while before inspecting. Any coolant or water will be on the bottom of the jar.
 
Hi,
If you check the Touch Control fluid like Cubfriend said above, the Cub owner's and operator's manuals say to check it with the arms in the rear, or down position.
The fluid rises in the unit as the arms go to the rear. If you check it with the arms ahead, it will look low on fluid, even if it has enough.
It's overfilled if filled with the arms ahead. :)
