Flooring it on the freeway? - PeachParts Mercedes-Benz Forum

If you aren't flooring it occasionally, your vehicle is grossly over-powered, which is wasteful, but typical in the U.S. Long ago I was in Indonesia when they were advertising the new Super Kijang minivan with the new powerful 1.0 L engine. You should see the loads they carry there. People say my 2.4L minvan is under-powered, but if I floor it so it downshifts and let the 4 valves/cyl breath at high rpm I can pass easily. Don't be afraid to spin your engine. That is where the HP lies.

My brother's W116 300SD did not smoke at all when he first got it and it has no emissions equipment besides the turbo. It needs a valve adjustment now but still doesn't smoke much. These cars should not blow large amounts of smoke if they are kept up properly

No they should not. Unfortunately people re-engineer the IP control devices and end up with smoke.

Neither of my 190s smoke.

For all the comments....

I'm out on a Road Rally in the Coupe right now , apart from the egr I do try to keep it bone stock as five decades of practical experience teaches that stock lasts longer , runs better and is more economical in the long run .

I have rebuilt the engine , re sleeving it as the DPO's ran it on unfiltered canola oil and anything else they got cheaply .

I rebuilt the turbo recently as it was passing a fair bit of oil into the intake stream and wasn't fee to spin , had radial and axial play , a loose circlip in one of the bushings blah blah blah , I replaced the shaft and so on , this reduced the blue smoke entirely .

Replaced all five injectors with good ones I tested on a buddy's pop tester .

I'm far from home having fun but discovered early yesterday morning that it will no longer exceed 85 MPH unless going down hill and when first I bought this car with it's bad engine (scored cylinders from coked up veggie oil) , it blew tremendous clouds everywhere it went but ran all the time @ 185 in traffic and easily went to 125 MPH with throttle left before I chickened out so I'm sure there's some little thing I've missed , why I want to learn IP timing very soon .

My other two M-B Diesel's the Wagon doesn't smoke , period .

The 240D smokes @ idle in gear but by the time I'm across the intersection from a dead stop , no more smoke so I know they're not supposed to smoke , I wonder why/how some folks don't get this simple concept .
