Here, Maryland
Was cruising down the road not long after having turbo/boost issues. I heard a "poof" noise and lost all boost. Flooring it would only just let me maintain 60 log enough to pull over safely.

Car had steam (coolant smelling) spewing from the intercooler/radiator/intercoolerpipe area. Won't restart after adding coolant. Car didn't appear to overheat. Does this scream anything besides blown turbo? Also I'm just outside of Fremont, IN.
 
LONG shot theory here.

Referencing your other post about not getting much boost.

I think your HG is blown. Explains white smoke from previous post, "poof", and no start.

Here's where my theory gets a little far fetched but maybe will spark some ideas.

Your previous post mentioned no boost, crappy idle, stalling, and "whistle". I think there's an issue around the intake manifold. I blew out my biss screw and my car did all of those things.

That could lead to running lean. Unaccounted air enters manifold after MAF. Lean condition increases engine temp that you did not see because...

I know for sure on 1g's the temp sensor for the gauge cluster probes inside the thermostat housing and I "think" 2g's are the same. If you run out of coolant your reading will be off. The CTS for 1g's is also mounted there. Perhaps the probe for CTS got an odd reading and flagged the cel?

Check for coolant/oil mixing and a compression test to confirm. Got a bad feeling that if it did overheat that head is probably toast.
 
Just curious, when you say it didn't want to restart after adding coolant. When you went to hit the key, did the engine seem to 'lockup' I.E.; either barely budged or spin over maybe once then stop? Or did it turn over like normal (or a bit faster) just didn't start? At first I thought IC piping blew off but you said something about a smell of coolant, gut feeling went to head gasket burned between a couple cylinders with a possible coolant passage burned depending on above question. Guessing the engine spins over normal if not a little faster than normal with an odd sounding hint of 'I'm kinda firing' but something isn't right, I've lost two cylinders.

I'd personally have some fun with that. Needs tear down anyway..I'd figure out which two neighboring cylinders are dead, easy halfass compression test. Then pop the TWO roller rockers off of ONE of the two dead cylinders, INTAKE cam. Next cylinder do the same, but on the exhaust cam.

My head hurts now, I thought I was onto something in a 3 cylinder sense but doing that I think the 2 cylinders will not like each other in some way.

Anyway, are you selling the engine or the car?
 
Im still leaning towards a IC pipe or intake gasket.. Boost leak of sorts..

What was the scenario when this happened? Were you just getting up to speed, in boost, maintaining a constant speed for a while?

Shop says you have rod knock? Oh really? What did they do to get the car running again?
