I just went through the absolute bear of a task that is replacing both turbos on my gen 4 (2012 MKS Ecoboost) on jackstands. When I first started the car after priming the oil/coolant lines (cranked w/o fuel or spark for ~10 seconds 3 times), white smoke came out of the exhaust, but after a minute or so at idle dissipated. I took it for a test drive around my neighborhood, gave it some gas, and **** YA I have boost now, but there was smoke coming out of the exhaust and engine bay.
From my not-so-experience, it smells like coolant. I could definitely be wrong though. I looked at the front turbo coolant lines and didn't see any leaks. Smoke seems to be coming from both the front/back turbo/downpipe areas, however I don't see any leaks :/. Wonder if it could be left over penetrant from removal? I used a whole industrial sized can of PB Blaster for the job...
