sorry about my crappy post, buy yea it had a leaking radiator which i replace with a kayo, and also did the oil and filter change.

according to me its, its not blue smoke, its white.
thing is that when you start the car with the cap off, it blows the coolant back out. Thus its the head gasket.
But the funny thing is that its consumed a lot of coolant which its puffing out and also has used up all the oil i put in.
p.s. i filled everything up to the correct capacity, and checked all of them. so no i did not over fill oil.

thanks for your advise guys
