Had a new turbo fitted last week. Have taken it easy since, not going beyond 3k revs (don't know why as I have 12 months parts and labour warranty!). When I do floor it beyond 3k it smokes really badly. When the last turbo went, it drained all the oil in the space of a few hundred meters (lucky there was no engine damage!) so I figured there must be loads of soot/residue in the exhaust. That is what the garage think too and say to change the exhaust for peace of mind. Coolant and oil levels seem fine. Will the exhaust clear in due course? I'm just worried of the potential hazards of other motorists driving through the smoke.
