problems in a Jac Refine

Hello, who can help me with a JAC Refine, began to lose oil and do not find the corduroy. They already changed the packaging, and nothing.

I do not know if you mean that you spend oil or escape, I suppose it is the last thing, if so, you will have to ask if they changed seals of the camshafts and if the plane of the cylinder head is rectified, try to observe if it loses for the upper part or it is by any side of the block, because it can be from a block or button Where to go to be able to help you with this corduroy. Greetings!!
