Junkyard Find: 1981 Buick LeSabre Diesel
Ah, the disastrous GM diesel V-8 cars of the 1978-85 model years, equipped with failure-prone engines that scared generations of Americans away from diesel cars. Nowadays, of course, diesels work just fine (except when they don’t), but it’s good to see the occasional reminder of these miserable GM cars in the junkyard as part of our American automotive heritage. Only problem is, just about all of these cars were crushed or had gasoline-engine swaps decades ago (I recall helping my uncle drop a Chevy 307 into a very clean Olds 88, around 1988 or so).
Here’s an extremely rare example that I found in a San Francisco Bay Area self-service yard last week.
With gas prices out of control thanks to events far away, the cheapness and fuel efficiency of the diesel engine seemed appealing to many Americans who might have dismissed it as a stinky, clattery, hard-to-start Freightliner powerplant just a few years earlier. A big 350-cubic-inch diesel V-8 making 205 lbs-ft of torque would make a B-body LeSabre get out of its own way reasonably well, too.
Sadly, The General made a sturdier version of the 350 engine block to deal with the higher compression ratios of a diesel engine, but then he thought he’d save a buck by using the same cylinder-head bolts and bolt pattern as the regular gas 350. This allowed the diesel engines to be built using much of the same machinery as their gasoline brethren … but also encouraged head gaskets to fail early and often. Many did.
There were other problems with the Olds diesels, but it was all the blown head gaskets on eight-month-old cars that really did the damage to GM’s already-battered image.
Could this be the actual mileage, or is it really 118,053 or 218,053? The car seems too nice for the latter figure.
There they go, Elmer!

- Daniel J I had read an article several years ago that one of the issues that workers were complaining about with this plant is that 1/3 of the workforce were temporary workers. They didn't have the same benefits as the other 2/3 of the employees. Will this improve this situation or make it worse? Do temporary workers get a vote?I honestly don't care as long as it is not a requirement to work at the plant.
- Kosmo Tragic. Where in the name of all that is holy did anybody get the idea that self-driving cars were a good idea? I get the desire for lane-keeping, and use it myself, occasionally, but I don't even like to look across the car at my passenger while driving, let along relinquish complete control.
- Bof65705611 There’s one of these around the corner from me. It still runs…driven daily, in fact. That fact always surprises me.
- Master Baiter I'm skeptical of any project with government strings attached. I've read that the new CHIPS act which is supposed to bring semiconductor manufacturing back to the U.S. is so loaded with DEI requirements that companies would rather not even bother trying to set up shop here. Cheaper to keep buying from TSMC.

Back in the late 80's I owned a 1980 Olds Toronado diesel coupe. It was charcoal grey with a maroon velour interior and most options including a steel sunroof, no vinyl roof but oddly no tilt wheel. Bought it from the original owner for a mere $500 who had a new Goodwrench motor put in under warranty. I did have a very good aftermarket fuel/water separator which I think kept it running well. I got a couple of fairly reliable years out of it (28 MPG highway!) with normal maintenance mainly a rebuilt brake hydro-boost unit(since diesels had no vacuum the brake booster was hydraulic and connected to the power steering pump) new alternator, glow plugs and their controller. Then around 100k it starring making demonic sounds like a death metal band and blew up. I thought about buying a 307,350 or 403 and drop it in but I figured I'd cut my losses and sold it to a E-body aficionado.
About two years ago I stopped by a classic car shop here in Portland that always has some neat rare stuff and occasionally has some other rare but not-so-neat stuff. That day I was in for a surprise: tucked in the back was the Malaise-y-est brown 1980 Oldsmobile Cutlass diesel complete with Malaise-y opera lights and a brown vinyl roof. You could have eaten off any part of the vehicle you desired and the original owner even took to removing the old registration stickers from the plate before applying the new ones. The odometer showed 12,741 miles confirmed to be original despite having a 5-digit display. I regret not asking them to start it up for me but part of me wonders where that car is now. That shop later picked up a 1976 Granada Ghia with 32,000 original miles and all whore-house red but when I saw that, I was there mostly for the Packard Super Eight.
