[diesel_mercedes] Excessive Exhaust Smoke

 



Thanx Rob ;

My Son was adamant I shouldn't rebuild the turbo charger , a buddy of his who's a top flight Mechanic did one and it still smoked the tell tale thin stream of blue smoke.....

I bought Kent Bergman's up graded kit with new shaft and worked very carefully but who knows ? .

It did help the power but not as much as did bumping the timing .

The impeller wheels were much cleaner than I expected when I took it apart .

I saved the old shaft in case anyone needed  a good used one .

I'll post here what ever I find or  do to it .

Nate,

If you rebuilt the turbo, it should be fine, as long as the parts weren't damaged.

I had some smoking issues that I hoped would be sorted by a Turbo rebuild, yet they weren't.
The turbo rebuild sure helped the power, and was well worth it.

Well Mark ;

It's grey/black smoke so I *think* so ~ typically turbo smoke is a steady thin white or blue smoke at all loads / speeds .

I overhauled the turbo last Summer so it's entirely possible I didn't do it right but before I go there , I need to address the excess fuel issue .

I was looking at an '85 300D yesterday and the IP had been removed without touching the oil filter canister ~ I'd love to hear the details of that as I want to swap out the IP on my '84 Coupe .

I'm already resigned to replacing the turbo but not until I know the fuel injection system is 100 % .

Are you sure the smoke is coming from the IP?  From the symptoms, it could be from leaky shaft seals in the turbo....
