i know its not a ford but it is a performance car so i hope somebody might be able to help!i have just been offered an evo 4 with tax and mot for £600,my friend is away to be buying a house and he is really desperate for money.the car has a couple of faults,the most severe being it blows the dipstick out when you thrash it,could it be a problem with the breather system,an o ring on the dipstick,or a terminally knackered engine.and is £600 ridiculously cheap and if worst comes to worst could i break it for more than that?im only buying it to sell on and help a friend out as a cosworth is enough of a worry to keep going!
