700 cc dinli atv mixing water to oil

[Shadow1]

I have that issue that one of my atvs is mixing water to oil even after i changed the seals of the water pump !! Any ideas??

A blown head gasket can cause it...

You should check it first..  Look for small bubbles in the top of the radiator or the overflow bottle.

There could be wear on the waterpump shaft causing water in the oil, or corrosion somewhere near a gasket or O ring, corrosion in a frost plug in the engine somewhere, a crack somewhere. Most of those won't make bubbles in the coolant.
