You know anything about the numbers? Displacement, Torque and so forth? Beautiful sound by the way

1982 Cadillac Coupe DeVille DIESEL

Have you ever seen one of these in person? Not many are left today. This car has been gone through for reliability, if you can consider that possible for an Olds ...

Great!! See my 1981 Coupe Deville Rare V6! also here on youtube. I have owned an Olds 350 diesels, really no issues. You have to know how to run and drive them to ensure lasting mileage! In the 80s people did exactly the opposite, get in drive and destroy the things. By the late 80s most of the problems were gone, but people lost interest after all the troubles. My grandpa had a 1978 Olds Delta Royale Brougham that had the engine catch on fire when I was 6, I am sure it was the D block. Great!!

True! I had mine checked out by an "older" mechanic at the dealer & he said mine doesn't even need the GM pellets yet. These engines (esp. the power) get a bad rap by younger dudes because they are used to 0 to 60 in 10 seconds! LOL. People have to remember back then luxury cars were built for comfort, not speed, & the national speed limit was 55. I know a guy who's dad bought an 84 coupe with the HT4100 new & he had 175,000 miles on it & not one bit of trouble. Its all about maintenance.

Good questions! I'm not sure why GM didn't ditch the 5.7 IDI in favor of the 6.2 IDI after it was introduced. I know they introduced the better versions of the 5.7 in the early 80s while the 6.2 was being engineered/introduced. I would imagine it was for business reasons; they wanted to get a return on their development costs by selling the rehashed versions. The 6.2 does fit where a 5.7 goes, though as far as I know it is not a bolt in gig. Search for "6.2 diesel Cadillac" for examples.

That thing sounds like an old Mack truck brah.....LOL! I have a 1984 Coupe DeVille with the "dreaded, never runs, explodes, don't buy, take you to a mental hospital if you do" HT4100 engine. Mine has 24,000 original miles and I lucked out because I actually got one of the GOOD HT4100's! Now theres a nice, smooth quiet ride. And as for mileage, I've actually gotten 27MPG on the highway crusing at a nice 60 MPH. Needless to say I baby it because I want to keep the engine running well.

I currently have this 82 Cad Diesl. as you mentioned the head bolt problem which I current have. I'm having trouble finding the right head bolts? The replacements that I've found say they don't have the studs on top. So....question: is it nesessary to have the bolts with the studs on top? Do you know where to find them? Oh by the way I enjoyed listening to your vid...POS lol. very good. this particular cadillac is in mint condition with 50,000 orignal miles. Thanks

Dude u rock for having that in that cond. Your right about the number of those that got trashed/wasted. I think they made FAR fewer of those than the 4100s. Wonder why gm used the weak 200 4R trans & not a TH 350/400? That tranny can get torn up from the 4.3 chevy truck engine. So who knows why they used it with the V8s. But looks like u eliminated most of the common issues. happy motoring. I think fuel economy was close to 30mpg for the folks wondering.

Corvus Casull commented on 04 Mar 2011

It did have a WTS light, yes. I would imagine that the 5.7 IDI would NOT handle a turbo. I just don't think it has the strength... unless you had custom pistons made that were very low compression and even then you'd probably still blow head gaskets. Speaking of Cadillac diesel swaps, you can find several videos of people who have swapped 6.2s into Early 80s Cadillacs. There was even a 70s Seville that had an Isuzu 4bd1t under the hood on eBay recently.

Yes, 350 Diesel has always fascinated me, sound, smell, etc. Diesel is very popular in Norway, especially when it cost 50% less than gasoline. The only "problem" is a cold start in winter when the temperature falls below 0 F. A neighbor had Olds Delta 88 1980 engine with 500,000 original miles. Use the blockheater summer and winter and change the oil every 1500 miles was his advice! I will take to upload a video soon, a rare car here too ..

Maples01 commented on 21 Apr 2011

@PITBULL35383 The 4.3 came out too late, as this is when the market fell due to the ABC news report demonizing the Oldsmobile Diesels. I once read a report on the prototype v-6 they had in a front wheel drive car at their testing ground, they hammered on it, serious abuse to prove it's durability, it won them over. At the time, the FWD cars were getting 4 cylinders for economy, the 4.3 had economy and power, but was discontinued.

ClassicTVMan1981X commented on 26 Aug 2011

@CorvusCasull 1980 and 1981 B-body Bonnevilles. From 1982 to 1985 the Bonneville name graced the G-body intermediate class (a la Oldsmobile Cutlass and Chevy Malibu), but the diesel option was discontinued in September 1984. Realizing Pontiac drivers had no B-body version of the Chevy Caprice/Oldsmobile Delta 88, during 1983 the Canadian arm of GM brought out the Parisienne sedan and Safari wagon to USA Pontiac dealers.

Corvus Casull commented on 13 Aug 2011

With the DX version of the 350 IDI, GM was close to getting it right. But the first couple of releases were absolute junk. (Of course much of the problem was a populace completely clueless about diesel engines) An avid hobbyist can make one of these fairly trustable as mentioned in the video. A lot of guys do look for the DX block to convert them into high horsepower gassers. Its very doable.

Corvus Casull commented on 04 Jul 2011

What media outlet started that disinformation anyway? Its annoying. The percentage of people who think the D and DX 350 IDIs were merely a gasser Olds fitted with diesel parts must be at least 95%! What this shows is that most people know very little about engines. No basic light duty passenger car engine could withstand 22:1 compression in original stock form, or at least not for very long!

moparmania74 commented on 18 Feb 2012

its my goal to someday get a 350 diesel and rebuild it, making it as reliable as i can. and then put it into an old gm station wagon of some sort. probably early or mid seventys oldsmobile. and then converting it to run on vegtable oil. it would be AWESOME for road trips, and so cheap to run. and you could brag to everyone what kind of mileage you got, plus how little it cost you for fuel!!

viper5gm commented on 09 Jul 2011

@CorvusCasull It was a 455 from a 1976 olds 98, I just got a 1981 cutlass with a rebuilt 5.7 diesel to have a spare motor for the caddy. The deal is if I pull the engine & Trans out I can keep them and give the body back. I have been running it around to see how it is before I pull it out and it runs perfect, No blow by at all and nothing going on in the cooling system so it's a go

bigchevy80 commented on 04 Oct 2012

VERY good and informative video on these beasts. I've owned two 350 diesels in my life: an '81 Buick Century and an '84 Oldsmobile Custom Cruiser wagon. Both had been rebuilt and had all the updates done to them prior to my buying them. Got many good miles out of them before I sold them to other 350D enthusiasts and I'm sure they are both still chugging along somewhere.

Corvus Casull commented on 04 Sep 2011

Here at 6,000ft it was very slow, but I never cared. I ran TCW3 2-Cycle oil as an additive. Mileage was good, but not that impressive. The pump was turned up slightly and advanced about 2°, it averaged about 17-19 mpg. Hills at altitude played a huge factor in lower mileage also. At sea level on flat land I bet this thing would have been able to pull mid twenties.

Corvus Casull commented on 20 May 2013

Another serious compliment! Thanks! Though I couldn't in good conscience actually compare it to the Macks of yore. I imagine the remaining HTs are not as horrible as everyone remembers. People beat the snot out of cars and then are furious when they grenade, but I bet if you baby that old Cadillac and keep mind of its weaknesses, it'll do fine.

BonhommeRichard91 commented on 13 Dec 2010

I wanted to buy an 82 Coupe DeVille with this engine but the guy wanted way too much money for the car. It only had about 25,000 miles on it but there was engine oil pouring out between the intake manifold and the head. The 350 Diesel is one reason why the American public got scared away from diesels. Nobody wants a diesel passenger car.

caddydaddyfleetwood commented on 03 Mar 2011

did it have a wait to start light? i wonder even with the ARP bolts if a turbo would be too much for the motor... i was actually thinking about putting a cummins turbo in my cadillac because of parts availability and reliability. i never had any luck with that metric 200r4 so i replaced it with a th350 and 3.08 ring gear.
