I have a 2004 Mazda 6 V4 2.3L, I am pretty sure that a rod is broken or something (because the engine knocks, I have had two people that were interested in buying it and not buy it because its a rob). At start up there is white smoke but it goes away after a little while, don't think it is a head gasket because there are no other symptoms. I think gas is getting in the oil, it kinda smells like gas and when I changed the oil, after running the car the dip stick was quit a bit higher then what it was before I ran the car. There was also metal shavings in the oil filter. I have about $530 in the car (Including purchase, taxes and parts). My question is, would it be a good idea to sell the car or fix it? Or should I buy another Mazda 6 and use this one as spare parts.
If i just buy another Mazda 6, what is a good year that is fairly interchangeable from a 2004?
Is this a common problem with 04 Mazda 6 or just the V4 engine?
