This is how I've spent most of my weekend:

P4303517.webp
P4303518.webp
 
Don't know whether it has reduced my blue smoke... I'll go for a drive in a while and get my wife to follow.....

Ok so my wife was driving behind me for a fair bit the day before my rebuild. So my "blue smoke situation" is still fresh in her memory (fresh in her lungs...)

Tonight we went for a drive around the neighbourhood with her behind me again in our other car. I did some quick accelerations, drove at 80 km/h for a bit, and went up some steep hills. I also tried a heavy downshift going down a steep hill. She says there is no more blue smoke, only a bit of white/grey on acceleration, and a bit of white/grey on gear shifts uphill. She says "95% better, but it still smells a bit like diesel."

So overall, I'd say it was a success. Under $200 for the rebuild kit with shipping, about one solid day of labour, and no more smoke!

don't you have to get the thing rebalanced?
Click to expand...

The majority of the weight is the exhaust turbine and the steel shaft. But you don't need to separate them during the rebuild (actually I don't know if it is even possible to separate them). They are balanced together at the factory (you can see where they have drilled a little bit of material off the turbine).

The fresh air turbine is also balanced at the factory -- you can see where they have drilled a little bit of the aluminum away. So theoretically, with both pieces balanced independently, it shouldn't matter which way they go together.

However, just to be safe, I carefully marked the fresh air turbine and the shaft, and put it back on in the same position. So the only thing which "isn't balanced" is the new nut which comes with the rebuild kit. It's pretty small -- 12 point 8 mm nut.

Anyway my "turbo whine" sounds exactly the same as before, and performance is the same (unfortunately -- I was hoping for some magic horsepower...) Just no more smoke :D
 
is there a special tool to remove the factory nut???
