Some of you may know i was driving down the motorway when aload of white smoke started coming out of the exhaust and engine was rattling. Ive taken the rocker cover off and everything looks normal Ive taken the Manifold and Turbo off and no visable oil in exhaust side of turbo Drained Water and no Oil in the Water Drained oil was abit black but thats prob because ive not changed it for a while. The Rattle seemed to come from the Top of The Engine Anyone got any ideas? Also if i need them where the hell can i get piston rings for Wiesco 74.5 pistons? Cheers
