on last tread when i was talkin about fuel pump i came to bizzare revealance..ive noticed that the oil pipe has something mudy brown stuff on it, and that on it is little greasy stuff..and also it was little wet..so our friend Jug said to me that it was blown head gasket..and he was right ..because i dont have any leak in mine cooling system..my question is how much is this dangerous to mine motor because the engine is loosing water,but not so much, and it is mixing with oil because of blown head gasket..and is this big job to do, to change the head gasket..because i think to change that gasket and all other gaskets..how many other gaskets are?...thanx
