She has always been pretty peppy for a n/a, today I took her out for a wild ride...
REALLY stomped on her, and she was doing good, but now is sluggish. Idling rougher, power is real low, but not fuel starved...
Much more of a dog than before I let it rip-
it was a super hard high speed push.
What's up with this?

btw, just grabbed some diesel purge...

Jimmy,

You probably overstressed the engine and broke something. Maybe a ring or a valve. Its not a good idea to beat the sh** out an old engine.

Another case of 'If it ain't broke, don't fix it". If something is runnung well, leave well enough alone.You may need more than a WVO conversion now.

"You probably overstressed the engine and broke something. Maybe a ring or a valve. Its not a good idea to beat the sh** out an old engine."

Haha, that's funny. What I've found is these engines like to be revved out and driven hard.. but that doesn't mean run them at redline or at the rev limiter for minutes at a time.

Maybe you just free'd up some carbon deposits that got lodged somewhere.. keep running it hard!

I am curious to know how you came to this conclusion. I must admit that it is a pretty widely accepted theory, but I just don't get it.

Nearly 200,000 miles in Mercedes Diesel automobiles

It's a fact.. if you baby your diesel it will run horribly.. everything gets all clogged up with soot from lack of flow through the engine. Keep it to the floor and it will run like a German clock.

My idea of an Italian tune-up..........On my way to work, I have to get onto the hiway, so as I'm on the on-ramp, gear selector in third, I will press the pedal more and more as I quickely build speed while looking in the rearview to see how much soot is coming out. When the rpm's are at around 3500 I will lighten up on the pedal then put it in 4th without stressing the tranny. Just before I hit 4th, there is no more soot. I do this every couple of days.

I agree with P.E. that mashing your foot into floor and spinning all that heavy mass up to red-line, is not necessary to blow carbon, in my opinion. I would think that you are running a higher risk doing that than by not running it so high and leaving the small amount of carbon left inside could!

People here say run them hard, drive like you stole it..........Well, I don't disagree with that completely, 3500 rpm is as high as I want to take mine.

Wow, BB, I thought I was conservative when I run the 603 up to 4200 in third with maximum pedal.

When I did a head gasket last year, it was pretty clean in there for 235K!

I've had mine up higher than 3500 a few times but it doesn't seem to do any better than 3500, IMHO Brian....

Yeah, how do you drive one of these without getting over 3500?


Change fuel filters, running hard, pulling lots of fuel, filter clogs, etc, etc..


The great majority of us run out high mile diesels what you'd call hard and have no problem. If doing so broke something, it was weak and needed fixing already. Better now than when your half way into a long trip, yes?
