What a beautiful car. I have a 1978 and 1979 Seville diesel. Early on I learned as much as I could about these engines. I can and have rebuilt my injection pump and injectors. I did away with the glow plug controller and did a manual switch on both cars, added a fuel separator and electric fuel pump. Those old girls fire up every time
I had an 81 GMC truck with that engine. It was in a company truck, and I hated it, noisy, stinky, and no power. First engine was replaced at 5 yrs, cause it had a miss. Replacement engine had the same miss from the get go. One day I heard a Connecting Rod starting to knock, so I kept driving it, not reporting it to the Fleet Mechanics. About a month later, when I started it, it was Bang Bang Bang. Good, I left it running and walked over to the Fleet garage, and asked the head Mechanic to come listen to the weird noise the truck was making. We could hear it from about 200 ft away, and the mechanic started freaking out, SHUT IT OFF SHUT IT OFF!!! I took my time getting to it, but the mechanic was running, but it didn't matter, I had locked the doors, as per company policy. I never saw that truck again
That's real nice to intentionally cost the company that's giving you the opportunity to earn a paycheck money just because you don't "like" the company vehicle they provided you. What's worse is that you're proud of it.
My Mom drove her 5.7 diesel Riviera for 20 years. , It was going to need glow plugs and she figured 20 years was long enough , but it looked like new. Nice Caddy though, love it
I have a 78 sedan part's car that I just scrapped the 350 diesel. I'm a gas engine guy and was low on space at the old place. I should have kept the lower end for a gas conversion. But when it came to it was either it or a bbc obviously the 350 diesel got to short end of the stick.
My first car was a 1980 Cutlas Cruiser Diesel station wagon. My friends called it the Blue Cloud because it was blue and would leave a cloud when I pulled away.
I have the same car, Just changed the injection pump 2 days ago. It made me nuts for some time now since it didn't have the normal symptoms of a bad injection pump and since it was the hardest part of the fuel system to change I tried fuel filter first, then all the rubber hoses on the fuel lines, fuel pump dropped the tank to look at the bypass valve on the fuel pick up and the sock to no avail and finally gave in and changed the injection pump and that fixed it (only took 2 1/2 years of just leaving it the garage when it would piss me off and then trying something else. Everything I tried would work for a hour or so then it would just sputter and die and wouldn't start until the next day and then it was all fine for 1 hr or so). I have 6 complete DX Blocks in my shop so parts are a plenty. It almost being a 455 powered 81 Cp Deville but the diesel part is why I bought it in the first place
Sir, what? My Dad had 8 or 9 vehicles with these engines and they all blew the head gaskets - except his 1981 Seville he sold recently which didn't. Really wish he hadn't sold that as I loved it.
@@nlemonj I was actually joking when I said they were good motors.i had one and it was a complete pice of junk and I never actually heard anything good about them
Yes it was a genius idea to use a gas engine and repurpose it to diesel which uses a lot more compression for which the basic gas engine wasn´t equipped to handle. The genius of GM believed in their uber head gaskets to magically develop the ability to be up to the task. And it certainly is to blame on the part that magic is actually not real and all things fell apart. In all honesty, it was a design decision that was so obviously flawed and stupid the one coming up with that must have had a stroke while on multiple different kind of illegal substances.
If GM hadn't been in such a rush to release that diesel program it would've been a totally different ballgame. After a few years of working the bugs out of that motor and changing a few design features, it really wasn't a bad engine....
We had an Oldsmobile delta 88 with the Diesel engine when I was a kid. My dad hated that car and the constant problems associated with it that he vowed to never buy another diesel anything.
Those GM 350 diesels were some of the worst Diesel engines ever built because it wasn’t designed to be a diesel. It was a 350 gasoline engine converted into a Diesel engine. We had a 1987 Vandura with the 350 diesel when I was a kid. It didn’t even make it to 100,000 miles. Then we had a 1989 Chevy Van with the 350 gasoline engine and it made it to almost 300,000 miles. It went through a couple transmissions though.
Even the V8 diesels have the same sound as the petrol ones do at low revs. Still don't take it away that they were very underpowered and produce a BHP figure way below average of an engine of its size.
@@kylescarfarm That’s funny! We had an ‘83 with the HT4100. My dad got it used in 1986 for my Mom. It was so slow that he thought there must be something wrong with it. Our mechanic said nope, that’s the way they all are.
@@kylescarfarm I can attest that the 84 sedan with the HT4100 is the slowest car on earth. It'll spin the tires if you give it about 10 seconds to build the torque.
They weren't converted gas engines. The block was diesel specific but Oldsmobile kept the same headbolt design and configuration as the gas engines resulting in head gasket failures. They also didn't install a water separator which caused corrosion issues in the fuel injector pump. Olds addressed these issues around 82 with the DX engines but their reputation was ruined by then.
Two things about this car---First-----The automatic antenna should be in a retractable condition when the car is turned off--which indicates that the antenna is not working . secondly, buying this common Diesel model makes it harder to find a fuel pump with Diesel fuel. Otherwise it is a good car provided the mileage is not high .!
Repairing the power CB antenna is pretty low on my priority list but it is on the list. The only repair I've made is to replace the fuel pump & it was readily available. It has around174300 miles.
@@kylescarfarm Buy that car and you would have to pay much more than a fuel pump---How about finding parts which are rare and far in between----Those old classic cars are for millionaire collectors touring the country looking for this and that --and paying a premium price for each available part, if you can find it to keep the car in it's original form--Otherwise----it is junk...!
@@williamlacentra2808 classic cars are for millionaires lol. What an idiot. I can barely get by and I have a 65 Catalina convertible, 60 Chevy apache, 85 GMC 6.2 diesel, 53 willys wagon, 81 Bonneville 5.7 diesel, 69 MG Midget.. and I can get parts for each one of them.
My first car was a 5.7 diesel powered Electra. My mother drove a Park Avenue of the same year (both 82's). The only problem I remember having is a thermostat...we upgraded them and kept trucking! Would cruise at 75-80 mph all day long!

Beautiful car and sound. Are there spare parts for this diesel engine?
And have you had any problems with the cylinder head?
If I ever need some parts I guess I'll find out if they are available. So far in 6 years I haven't had any problems.
NICE......

Hey would it be ok if I use this video for my UA-cam channel? I will credit you. I am attempting to complete a cold start collection
Love to buy
Sounds like a diesel...listen to the clackity clack!
Could this actually be slower than the HT4100 Engine from the next year's model? I'd almost want to say "NO".
I'm sure I can idle across a parking lot faster than a HT4100!

You got it! Both are Olds 403 powered!
Love to have one orginal diesel. But no i don't.
Hi Friend! It Fit a Detroit Diesel Silverado V8 engine?
Interior noise level?
I should make a video from the interior. It's not too noisy but certainly not whisper quiet like my 403 gas.
Sounds like a tractor.
Yeah. You're right. I don't know why anyone would want a beautiful car like that that sounds like a tractor.
The later 350 Olds DX diesels solved the issues of the first generation engines
Is it true that cadillic DeVille diesel have an gas mileage of 30mpg on highways wich is 7l/100km?.
