I just finished replacing both turbos with new OEM's on my 2012 MKS Ecoboost. While I'm no mechanic, I took my time, replaced all gaskets and oil lines. Only thing I didn't change out was the coolant lines themselves, but I did replace the crush washers. Torqued everything to spec according to service manual.
I did also remove the intercooler and clean/dry it out.
When I first started the engine after replacement (and "priming", cranking w/o fuel or spark for ~30 seconds), white smoke billowed out the exhaust, but after less than a minute subsided.
When going for a quick test drive, I noticed white smoke would come from the exhaust under moderate throttle, and sometimes under moderate throttle I noticed rough acceleration, which to me felt like a boost leak - could be a loose hose somewhere, i'm going to smoke test it later today.
Boost gauge seems to max out around 10 psi. Upon parking the car, I noticed white smoke also in the engine bay, which seems to be coming from the downpipes.
I jacked the car back up and checked for leaks, and couldn't see any. The white smoke smells like antifreeze to me.
Not sure what could be causing smoke from the exhaust. I did notice some water leaking out of exhaust as well, but upon doing the ol' sniff test, seems like pure water, not antifreeze.
What debug steps should I take? Take her in to dealership??
