I've been slowly working my way through maintenance jobs on my D1 300tdi, most recently, the exhaust/manifold was blowing, so I took the opportunity to fit a decat downpipe, all fitted fine, with no leaks. However, when checking, I notice I'm getting a small puff of smoke from the back of the turbo body, at least that's where it seems to be. Seems to be only on the overrun after revving the engine.
It could also be the EGR blanking plate, I guess. But is a leak from the turbo body a possibility? What could I check to narrow it down please?
Thanks
