Hey guys I have a bf f6 and it just had a engine change it had a mk2 gas engine put in instead of the f6 engine. Now it is using oil fast and the is heaps of smoke like all the time my first thought was turbo but it's still spooling properly and isn't showing and bad signs. I have only had the car back for less then a month and yes I am aware of the major power loss from having the wrong engine. Any help would be appreciated thank you
