I'm in KC, Missouri.  If you guys are interested let me know.  The sunroof seal leaks and the HUD doesn't work but everything else is in great shape.  I hate to part it out like this but I just dont have the time or anything to mess with it anymore.

Back to topic   :laugh:  I replaced the turbo unit with a rebuilt and known good one and the problem did not change.  More investigation and more ripping and I now have found the problem.  There is a VERY small hole in the number one piston.  The problem with this is the engine now has metal shavings in it and is going to need a complete rebuild   :icon_eek:

My problem with this is I have replaced every sensor and power module on this thing and now I dont have the energy or resources to do this.  Any suggestions now?

I'm trying already   :worshippy:

Sweet, thanks.  They have been here for over 15 years so I'm hoping that says something.  I will check them out a little closer though.

Tan interior TGP's are "light beechwood" in color.

"light beechwood" like the color of beer   :laugh:  mine are pretty "aged" too  :icon_mrgreen:  I thought this color was peanut butter or some crazy thing like that?

Spent way too many years programming....lots of time to think about torturing users   ;) :icon_lol:

There is a place here in KC that will rebuild the turbo for $300.  That sound about right or they trying to rip me off?

I was wrong....it was rebuilt in '02 by Dallas Turbo.

What makes you think I would shoot the messenger?   :icon_rolleyes:  Might hunt you down and stick a torx in your eye but I would NEVER shoot   :laugh:   :joke: :smilielol:

Plan "D" has a few options.

Get with Invasion1 (Dave) for #'s to the folks who rebuild his.
Learn how to replace a turbo center cartridge.
Buy a new turbo...GT28 or GT30 series
Get full coverage on the car and drive it off a cliff! ;) :laugh:

You will need a rebuild though. Most likely she sat too long...got a dimple in the seal and it finally let go.

Did I say plan "D"??  I must have meant plan "C"  :icon_eek: :icon_eek:

So basically what you're saying is the turbo (which was just rebuilt in 04) is a pretty paperweight and needs replaced?

It has a 4-way on it.  One side to the plenum, one to the modulator, one to the EGR and one to a screw.  I think the previous owner had done this once before as I dont think GM would   :laugh:

Last night the wind died down to nothing and I was able to get a good look and smell at the smoke.  It looked more blue than white and had a strong oil smell to it.  I also checked the oil level and it's now almost a qt low.  The coolant is full in the radiator and the overflow tank and I have good pressure in the system.

I guess with all the blooming and the wind I was smelling sweet and blue looked white...anyway, thats oil not water or tranny and the smoke was also coming from around the x-over and exaust system there at the manifold.

Any suggestions for plan "d"???

I think I have officially ruled out the vacuum modulator and now I'm leaning towards the water seal at the turbo.  Anyone point me to where that monster is?

My finger is pointing to the line at the throttle body. Follow that down and you will find the vacuum modulator. Make sure there is a T check valve down on the modulator with one side of the 3 open.

Hope this helps! ;)

That's the one I checked.  There is a screw plugging the open line but it is all clean and dry.

I feel your pain.  I have to park so far away from people I need a map to get in to the store.  I've tried to swing it in but like you said, WHATEVER   :icon_frown:

The line from the plenum is way smaller that 5/8 and goes to a T connector and a small rubber hose.  One side comes back up and goes into what I think is the cruise control and the other plugs directly into a small round metal something.  I cant really see it because it is under the turbo.

I hate not knowing what I'm looking for but from the description this cant be it can it?  I pulled the little rubber hose and its dry as a bone inside it.  It looks more like a air hose than anything else.


EDIT: - I saw small bubbles coming from the back side of the turbo and smoke coming from what looks like the exaust pipe and x-over where it meets the turbo.  Any thoughts on this?  Could it be a valve gasket?

White smoke is a tricky b*tch sometimes.  :icon_mad:

What does the smoke smell like? Is it a pungent turn your head ew smell, or does it smell like coolant or oil? The amount of smoke...are you fogging for insects or are you just covering your license plate from the coppers?

To start and the easiest thing to do...as Ryan said and pull the vacuum modulator line and see if there is ALOT of tranny fluid in there. If there is then pick up a vacuum modulator and swap her out. Will most likely take a few hours and a couple of WOT 3rd gear runs to clear it out.

If no tranny fluid there...then look for coolant loss or oil loss.

If you are low on coolant...it is time for a coolant system pressure test. If it is bleeding off and you do not see it outside the engine then it can be a coolant seal in the turbo or head gasket. You can do a cylinder bleed down to void the headgasket.

Also when you pulled the 02 sensor...did what was on there smell like oil or coolant or the pungent smell? Did it evaporate or was it dripping? If dripping did you grab a white paper towel and dab it to get a color from it? If it evaporated right away was it a steam or lingering smoke?

Just jamming a bunch out there to try and narrow down what the mosquitoe fogger is caused by! ;) :icon_cool:

Lots of info so here goes...

The smoke smells like oil...sorta...  It isnt one of those "holy shit run for the hills" smells at all.  The amount smoke could be confuesd for a forest fire by low flying planes   :flamingdevil:

When I checked the oil level it was about a 1/4" down on the stick from full.  Not to the add more level but it wasnt full either and I just changed the oil 2 weeks ago.  The coolant level was also a little low in the overflow tank and I know I topped that off when I changed the oil as well.

When I pulled th O2 the only thing that came out was the same white smoke and no fluid...on a side note to that it did make a wicked sweet noise   :gr_grin:  and after I shut her down the smoke still lingered out of the hole and the exaust as well.

I will pull the modulator line today and see whats in it.  Does ALOT mean pouring out or just full or anything in it at all?  Not ever done squat with one of these so I'm not real clear as to how much of what should be in it. 

Also I didnt see any coolant anywhere outside the engine.  The only fluid I saw was the oil sprayed right up front by the fan and on the plenum.

As for 3rd gear WOT unfortunately mine is not a manual   :icon_cry:  so I will have to settle for WOT by foot once I get it fixed.

Thanks for the ideas and starting spots...I'll let ya know what I find.

Sweet...thanks.  I'll change the seal tomorrow and see what happens.
