UPDATE

The guy has changed stem seal valves, put brand new head gaskets, bottom end gasket, brand new turbo seals

upon opening the engine..one of the pistons were chipped. So he put 1 new piston in there l..

Started the car yesterday instead of white smoke it is now smoking blue at high revs

We are confused now where the f** cud this b coming from.
