Blown Headgasket or Blown Turbo?

[mehsilvia]

Alright, so here it goes.
It was Track day this past Saturday, stated to be apx 120degrees on track, 4th session of the day, i start loosing power on my 4th lap.

Symptoms:
Still could drive, but no heavy throttle response. NO turbo spool, NO sound from the blowoff valve whatsoever. Drove off track, came into the pits, and as soon as i left the track, white smoke from the exhaust. When i start it up, there is immediately white smoke and a strange metal/rattle/grind that tends to build up then go away, build up then go away as it idles. Just lovely.

I have not had much time to work on it, ive just started with pulling the intercooler piping and intake. The intercooler piping was soaked in oil as was the blowoff valve. Oil on both sides of the Intercooler. Id say apx a Quart worth in the intercooler system (heavy on the hot side).

I wanna say blown turbo just based on what ive seen so far. Others indicate possible headgasket due to white smoke, however im running Water Wetter/water mixture and not coolant. (Though i did not drain the block of coolant, just the remainder of the system and radiator). I just dunno.

Plans:
Pull the turbo, inspect all lines, shaft play, etc . . .
Remove intercooler and of course clean everything out.
Pull oil pan and check for metal and capaccino coolant mix (thanks Mr Samurai)

Basic setup info:
Stock turbo, Intake manifold, Injectors and MAF
Greddy intercooler & oil pan
(most)Coolant drained and Waterwetter/Water mixture


Suggestions or comments anyone?


**UPDATE**

Found the answer = Blown Turbo!



Talk about shaft play, side to side, up and down, left and right, oh . . . id say about 1/4"

Cleaned out the intercooler and piping, inspected the exhaust mani, coolant lines, oil lines, etc . . . no other issues found. Drained coolant and oil, pulled valve cover . . .no issues found.

Gonna now pull the intake mani and make sure its all cleaned out. There was oil surounding the TB so im sure the intake plenum is gonna need cleaning out.
