Oil mixing with coolant

[metrohandi]

I have a 743 Bobcat and today one of the hoses came loose I repaired that then I noticed oil inside the coolant resivoir bottle. I checked the oil dipstick yet no oil is in the motor. Does anyone ever experienced this issue and if so how do I correct the problem. The machine is still starting up but I dont want to run it again till I can fix the issue.

Oil is at a higher pressure so often its in the coolant with no coolant in the oil. I had this problem in a VW diesel Rabbit and drove for awhile until I dumped it on a dealer. Possible causes would be a head gasket or cracked head/block. Is there an oil cooler that is cooled by antifreeze? If so that would be the think to check first. Get a UOA of the oil to be sure there is no antifreeze in it.

It sounds like a possible head crack. Just how much oil are we talking about?

Do you get bubbles in the overflow bottle when the engine is running? it does look like the head is cracked or a bad head gasket.
