Good day car gurus, I have this VW T4 with 4 cyl diesel engine. The engine has been overheating and oil is gushing out from the top cover and oil dip stick (dunno the correct terms ). The mechanics around (onitsha to be precise ) has done thier worst, now the car overheats every 2 to 4 Km.

I changed the top gasket as adviced by one of them and the problem became worse. As i typing the car is packed.

A friend advised me to buy a new engine (half and top) and i av started saving for that.

Is it better to buy a new engine? what type of engine is the best buy? or Can i repair my own engine and still run biz with it.?
