While this is a mercedes newsgroup....

Let's have a check. Yea, mercedes quality- how about the POS 3.5 liter 92+ 603 engines. Mercedes violated the bore/stroke ratio and getting to 300,000 miles would be *impossible*. I'd take any 1992 gm product against a 1992 S350 diesel!

You may be right on that one....

However, I'd still take a Benz anyday over any domestic, regardless.

At least 225k miles and ZERO blowby?

First I find out that I will never get 30+ MPG on my diesels.
Then I find that the Republic of Kalifornia wants $175 a year to "allow" me to collect and transport inediable cooking oil that is usually thrown away.
Now I'm being told that my diesels aren't going to last a million miles?

Where will it end?

Ain't it the truth! ... I'd guess there were and are people who would rebuild them at 100K or 150K for the same reason.

We have an example in this thread of a car that had the engine rebuilt only because it was out of the car already for a rear seal that could've been fixed without a full rebuild.

I bought my 300D Wednesday with at least 215K actual on the ticker (it's turning and I think it's very fair to assume that the car doesn't have LESS than what's on the odometer) and I seriously doubt it's ever been rebuilt. Couldn't prove that, but a number of receipts and records came with the car from the two original owners (both woman doctors) and the engine certainly doesn't look like it's been out and revamped and reinstalled.

Nevertheless, while there's a drip (!) or something, you can pull the oil cap and have virtually zero blow-by. (And yes, to whomever it was in the thread, I do mean "virtually zero blow-by.") ... Pull the cap and no oil splashes out at all; only a very small wisp of smoke emerges.

While there might be a few exceptions (like the 350 mentioned earlier, perhaps, I haven't owned one or read up on them) I doubt anybody makes an engine -- gas or diesel -- better than the average Mercedes. Heck, when she was in high school my sister punched a hole in the oil pan of my mom's 280SEL 4.5 (bottomed-out on a gravel road), then DROVE THE CAR 30 MILES home and said to Dad, "What's that red light on the dash mean?" (Edit: The car had no oil in it -- none -- by that point.)

Dad had the oil pan hole welded shut, put eight quarts back in her, started her up, and she seemed to run fine. But he drove her to Kansas City anyway (four hours) to let his most trusted (non-dealer) MB mechanic check out the piece, and the guy told him they'd rebuild the engine if he wanted them to, but for the most part it was fine. I think they replaced a few parts in the valvetrain just to be sure and dad was on his way, and in about the first 180K miles of that car's life that's all the major engine work that was done.

I'll tell you our family's 1958 220s story later ...

Well, imperceptible to the naked eye, anyway. Miles are nearing 290K, now.

Go figure, though. I've seen OM617's with a noticeable amount of it after 300K, but not so much with the 603.

Bah 400k mile examples pop up every once and awhile.

I knew it would be only a matter of time before the bureaucrats demanded their cut from WVO users.
Is that $175 a hazardous waste fee or a highway use tax?

Happy Motoring, Mark

And before anyone freaks out it's just an analogy, I know what knocking is.

This would be true if you was comparing a cummins to a gasser but these little MB'S spin just as fast as a gasser. Which just proves that much more how durable and efficient a MB engine is.

t walgamuth · #70 10-22-2005, 01:25 AM

think that the diesels turn as fast as the gassers. mostly. my gassers except the 500 all have redline of 6200. i think the diesels are about 4800 or perhaps less.

i just went to ebay and did a search
ebay motors, passanger vehicles, and then i hit search... not specifiying
the vehicle type... about a gzillion came back... then i clicked on mileage..
and sorted by the highest milage.... and there were about 10 pages
of fake mileages... and once you got down to real milage the first one was
a 400k diesel mercedes... then there were tons of diesel mb's and diesel pick up trucks...

you did not find a gas car until you were down in the 200ks...

then only ones with high mileages were the mb diesels and diesel pickups... mostly dodges..

t walgamuth · #72 10-22-2005, 01:36 AM

that is exactly what i would expect. and why i own both dodge with cummins and mb.

Check out my signiature...

I agree with you about old Caddy's. I had a 72 Sedan DeVille. The only car I've ever owned that compares to a Mercedes and I *will* own another one one day.

Interesting. ... Wonder when all went wrong for Cadillac.

My friend's family had about a '76 Sedan DeVille (green on green) when we were kids and it was an utter heap of dung from Day 1.

I think I can answer the question about Cadillac problems, like the old saying goes, "they don't make them like they used to anymore"
