well, I dont have any obvious leak in site, Im blowing tons of white smoke out of the exhaust under boost (atleast I think its white.) theirs smoke that stings my eyes really bad coming from the turbo area though, so I think it might be hitting my turbo and evaporating. Is their a coolant seal in the turbo that can go bad so it blows through into the exhaust? Do I need a turbo rebuild, Theirs barely any side-side shaft play same with in-out, now that ive ripped everything apart I have found that 2 of the turbo bolts (top ones) where loose enough to remove by hand And my PCV system has been sucking massive amounts of oil into the turbo aswell joy I suck. So now im trying to figure out if this is a purely turbo issue OR if I blew a coolant seal inside my engine and im screwed, completely broke-*** ******* screwed.

 

..I can't Really Post KNOWLEDGE on the TII engine, so I'll post what I have read up on it...the turbo is Both Oil Cooled and Water Cooled.So,I would "guess" that your Turbo could be the Culprit.Do a Compression check to See if your engine's compression is OK.Also,see if you can get a Pressure test done on your Cooling system,if you think your engine is heading South...it's not Much Info,But it's a Start.

 

Pressure test? ive done it the old fashion way, Opening the radiator cap and checking for gurgling and no gurgling, their was air in the system so I did have some bubbling and splurting but once it got all coolant-filled (AGAIN) it stopped and seemed consistent, untill the thermostat opened and it overflowed a little, to my knowledge normal operating procedure. but one I drive around my coolant is going Somewhere. maybe mexico, maybe canada, **** if I know!

 

there are coolant lines in your turbo......and because it happens underboost I would imagine its the turbo. I would check to see if you blew a coolant seal. and if you did time for rebuild

 

Depending on which bolts were loose, you may be blowing coolant all over a hot turbo. The hardline that bolts onto the LIM is for coolant, so check it out and get new gaskets if needed (2 arrows on left side of pic), and also check out the coolant return line on the water pump housing (arrow on right side).

 

no both of those are tight, I had an issue with them broke a stud replaced with grade 10.8 bolts and now their not going anyway and I even found crush washers that work for the big banjo bolt
