Just bought r1 with 85000km, from japan, no mods,and is still at dealership. Dealer assured me the oil on the underside of car and in exhaust was caused by blown turbo's that he was in the proccess of replacing. Just wondering if this is a possible scenario, and also how to tell if it could be an engine seal of some type. It's obviously not the pan because the oil is working it's way through the car.thanks

 

Could be the turbos. Could also be oil control rings and/or a PCV valve.
