Normally, this machine has no direct connection where hydraulic oil can enter the engine.

Can you tell me what clues you have as to why you believe this is happening?

Does this machine have some special attachments?

Are you losing the same amount of oil from the hydraulic tank as you are gaining in the engine oil? (Have you measured the same amounts repetitively?)
