In another thread I crowed about my acquisition of a cheap 87 300D. The owner was about to send it to the crusher and let me have for the crusher price of $400. Among its many problems I was told that "the turbo didn't work." And sure enough, it was sluggish. And when I floored it it would belch these huge billows of smoke.

Replaced the air filter, changed the fuel filters, changed the oil. Drove it hard. The more I drove it, the more the smoke disappeared, the quicker and stronger it seemed to get. But it still didn't seem to be as quick as it ought to be.

So I removed the ALDA. Had been reluctant to do it on my other cars...afraid I would damage something. But on a car I got for $400....what have I got to lose??

All I can say is....WOW! WHAT A TRANSFORMATION!!! The crusher-bound dog has been transformed into a beast in just two days. All the power I could ever want and then some!

My only problem: I'm finding it difficult not to smoke. My SDL doesn't have its ALDA either, but I have no difficulty preventing it from smoking. So not sure what to do about that. I guess I can always shim the ALDA and put it back.

Anyway, that's my success story for the day!

Congratulations. I once got a great deal on a 240d which had contaminated fuel and a stuck caliper from sitting. It was a nice car.

If you hang around diesels enough you will come across one or two with these simple problems.

Come to think of it I sold one cheaply that years later I figured out had bad glow plugs.

theres a patch or gum you could try

I smoke (again ), but the w210 e300doesn't, even on B100.

maybe the exhaust is just terribly sooted up from the previous life of being a "dog" and smoking like a chimney

I have wondered if it will improve. But it seems like smoke is from unburnt fuel....exactly the same smoke that happens if I mash the pedal on my SDL. But it just seems to happen more easily on the 300D.

unburnt fuel would be white

I don't believe that's correct.

I think completely unburnt fuel would be more of a white mist, overfueling/incomplete combustion/partially unburnt diesel is black.

That's what I meant....the partially unburnt diesel....that's clearly what I'm getting with the ALDA removed.

That's not surprising as biodiesel has fewer particulates than dino fuel.

I agree that unburnt fuel gives white smoke, while black smoke is caused by fuel burnt with too little air or oxygen. Figure out how to get more air in. A good air filter and a well performing turbo are things to look at.

It's because I removed the ALDA....the solution is for me to train my foot.

Yes, it might be your foot - but on the other hand in your original post something was said about "turbo not working". If you have eliminated a suffering turbo from the equation, you will need to train your right foot. Same thing happened to me

Think you can keep your right foot off the go pedal long enough to update your sig line?

Who, me? It's going up for sale. I might sell mine before you sell yours!
