the car runs awsome no problems at all but there is now oil and water mix in the whole coolant system and engine what could the problem be pls help i dont think its a head gasket it runs to good noo missing or anything i just bought the car

 

can you clarify? I havent got a clue as to what you are trying to say.
oil in the coolant system or water in the crankcase or both ?
I can guess, but what would be the point?

also, where do you live, mileage, etc ... ?
having condensation and water in the crankcase is not uncommon and not necessarily an engine problem .. but it is a driver's behavior problem.

you just got the car ! you probably have no clue what you are looking at since the previous owner probably didnt provide maint records.

change the oil and change the coolant and then see what you get and get back to us.

Catera V6 has oil cooler in top of block under plate beneath intake, which has a habit of leaking oil into cooling system. Blown head gasket normally will put coolant in the oil except Northstar which normally just overheats.

 

found the problem was the oil cooler just took it apart
