I am doing 617 turbo into 240d 4spd. The 617 starts and runs awsome!!!, but is covered in oil. Since the engine is on the ground I'm having trouble convincing myself to do anything other than the gaskets. The chain shows zero stretch but the tensioning rail has considerable wear. The rear of the head gasket seems wet and has some oil trail from the seam. Guys this engine PURRRS!!!!, so I'm really worried about messing it up. I'm not afraid to tackle the head job, but if the head is off then I might as well pull the pistons and hone the cyl....... You see where I'm going? I don't want to do a 90% rebuild, but I would like to take advantage of the engine being out. I have thought about just sealing it up with all new gaskets and finishing the conversion. PLEASE HELP I have a chance to get really ahead on this engine!!!!, or really screw things up???? WHAT SHOULD I DO?????
