Are the 300SD's Pure Diesel Engines!?

[BenzBoy8]

Well I noticed that my dad's chevy pick up is a gasoline Engine transformed into a diesel. I guess to cut cost.

But I am wondering if my OM617 was built from the ground up?

Probably was, just wondering....

[Palangi]

Yes, OM617 is descended from OM616, OM615, OM621 and other diesels.

[The Warden]

Yes, it was.

and what motor would that be?

the 6.2 and the 6.5 are designed and built by detroit deisel and share NO parts with a gasolene engine. And contrary to popular opinion the 5.7 diesel wasn't a gasolene to diesel conversion.

Ha dont be to fooled. My father has an 87 6.2 L and it is very much converted. You can see right away. I think thats why they don't last as long...

You must always remember ...Detroit's Q.C. is the CONSUMER.
They'll put ANY excrement on the road , if some fool will buy it!

Engineers ...IN AMERICAN AUTOMOTIVE Pursuits ????????????
"might as well dis-CUSS MILITARY INTELLIGENCE!

#2 Detroit has not the savy to produce an automotive DIESEL
#2a The Seven Sisters loose out if We go Diesel.

We can almost say that for any American Company.

General Motors is the main reason that diesel engines have a "bad" reputation amongst the general public in the US.

In the late 70s/early 80s when Mercedes and VW diesels were getting popular here, and VERY popular elsewhere in the world, GM wanted to jump on the bandwagon. In their rush introduce diesel-engined cars to compete with MB, VW, and others, they produced some poorly engineered and weakly built models which WERE basically conversions using a beefed-up version of the existing GM gasoline-burning small block V-8 engine design. Certain components of these engines were not adequate for the forces inherent in a diesel engine, and also many US customers, repair shops, and car dealers did not know how to maintain diesel engines. Subsequently most of them didn't last very long.

Click on the link below and scroll down a bit...there's two different articles on the "Oldsmobile 350 Diesel".

This ended up being such a fiasco for GM that it badly tainted the "average American's" perception of diesel-engined cars, and this negative image persists in the minds of many people to the present day.

We'd probably have a LOT more diesel-engined cars in the US if it weren't for this huge blunder by General Motors. Fortunately the negative perception that it caused here didn't reach Europe and elsewhere in the world.

I think I remember reading that nearly 50% of the cars on the road in Europe are diesels....The percentages are high in Australia, Japan, and most of the Middle East as well.

Hopefully they will become more commonly embraced in the US eventually. With fuel prices being what they are lately, that process might be sped up a bit.

Yeah right just like the power stroke is.

I have one and there isn't a damn part except maybe some bolts that will fit any other GM engine. I am a LONG TIME GM guy, going back 30 years.

You are blowing smoke on this one.

With routine maintenance these last just about as long.

What kills them are harmonic balancers that go bad and are not replaced when they should be.

Their IP's are not as long lived as soem but they are cheap to get rebuilt.

AND they are not subject to the cavitation related failure the powerstroke is famous for, AND the parts are nowwhere near as expensive. I will not argue they are the best out there but they are nowhere near what YOU are trying to paint them as.

[flash123]

Whoops, the powerstroke is not famous for the engine destroying pinholes caused by cavitation. That was a problem with 7.3 IDI Navstars. I have one of these in a 93 Econoline. I check the coolant every few months, so I don't have a problem. The Powerstroke is a Direct Injection Navstar and has a redesigned block.

I have been hauling livestock all over California and Nevada this summer and fall. I really need a newer truck with more power, but it gets the job done and it's not bad on the fuel bill. My wife's truck is a powerstroke with about 300,000 miles. It is our income, so we don't use it for hauling horses over the Sierras.

Don't blame Detroit Diesel for the crappy 5.7 and 6.2. They could have designed a good engine if Chevy wanted to build one.

GM wanted a cheap engine built on a modified big block gasoline engine. They got what they ordered.

No YOU are wrong, its the powerstrokes in Ford pickups with cavitation issues, its a well known issue if the coolant does not have the correct level of additives.

Its well documented and well known on the Ford Diesel boards.

Why don't you just admit you don't like GM vehicles instead of fabricating a bunch of falsehoods. Mercedes made more than its share of CRAP engines.....luckily most of those stayed in Europe. Ask people in Europe, they can substantiate this fact.

[carusle]

Yes, "TwitchKitty" there was a V6 conversion and Chevy used it in their small station wagon. Used to see them on the side of the road all the time.

My Powerstroke 7.3 (direct-injected) is an excellent engine, despite the rather slow acceleration and 15mpg average..but with an SUV, who really cares about fuel economy? It simply rules whenever I need to tow anything. Just last week I had to tow away 1000+ lb of waste glycerin, and the Excursion didn't even bother with the extra weight.

The engine has 100k on the clock and has NEVER had any major issues, injectors and glowplugs are original, etc. Best mpg was 17, coming down the mountain from Tahoe

[captainmonk]

one would hope a 1000lbs doesnt work your ford My 6.5 Chevy tows 1000 lbs reguraly with 197000 miles on her I just love my old stuff
