I currently have a Focus RS Mk3 in the workshop, initially the Ford garage diagnosed a cracked engine block ... but after bringing it back to my workshop, it starts perfectly but the smoke in the exhaust is immediate, a turbo breaks, well ... to confirm this break, I isolate the engine from the turbo by removing the air hoses, I restart the engine and notice a high pressure in the breather ...
Did anyone have the similar case, the related defects are important oil leaks and maybe the turbo broke (which of the egg or the hen appeared first).
All leads are good to take ....
