Oksay so after finding the problem i thought i d sharwwhat was racking my brain for so long! In the end it was a cracked piston crown....



Can u see where the metal is missing, i mean, WTF could cause that?

Anywayz no more smoking BUT im sure a couple of u cossie owners saw me smoking again on the Dartford crossing about a month ago ( could see the drivers laughing lol) after a new engine install (o miles) and properly running it in it smoked ever so lightly in 3rd gear on the overun but hasnt since so we will see how that goes.

Once again thanks for all input people!

Ill keep you posted or u can watch here
