Olds diesel market is still pretty hot in Europe & Scanandivia i got engs on backorder for some guys i do business with.
Glad to hear, they killed the passenger car diesel market for 30+ years in North America. If only they built the 4.3 V6 first, you know the right way, water fuel separators, extra head bolts and gee golly, long enough main bolts! Imagine those hooked up to the T50 in the new downsized 78 Cutlass, reliably getting 40 mpg. Then Turboed by the early mid 80's, performance and mileage way before the VW TDI. Typical GM, finally get something right, then cancel it shortly afterwards.
I've seen the 4.3 v6 mentioned a couple of times through out this thread, are all 4.3's diesel, or are there both gas versions and diesel versions? I just picked up a parts car elky that is supposed to be a 4.3 so I was just wondering.
My 81 Cutlass Supreme had a 5.7 l Diesel... it was the third engine replaced under warranty! When the third engine died... fuel pump failure, and the cost to fix it was quoted at around $2500 by a GM dealership I knew it was time for a ZZ383 I had been eying in Chevy High Performance. The diesel engine was the main cause for Oldsmobile's demise! Currently the mechanic who services my car and works from his home in Phoenix used to work at one of the Oldsmobile dealerships in Indianapolis for over twenty years and was THE champion at replacing these engines at record time. He informed me that this engine was the reason why Oldsmobile boarded up. They lost their shirt replacing two, three, and even four times the engine for the same car, all under warranty! But, it's the best boat anchor you can buy... someone may give to you for free or even pay you to haul it away!
There is the v8 4.3l diesel that came out in '79. And ended in '79.
Then some time in like '83 gm came out with a v6 version listed as 4.3l. On top of that, there was a rwd and a fwd version. I don't know enough about the v6 version. Others will fill the rest.
The 4.3 V8 diesel had all the same issues as other V8 Olds diesels. Almost no one has seen one, almost all were replaced with the 350 DX. They were available with the T50 5 speed manual. I believe they were 90 hp and 160 ft/lbs. The Olds 4.3 V6 was diesel only. It has one extra head bolt per cylinder and they are metric thread. It also had serpentine belt drives on both versions but were different. The FWD was lighter with aluminum heads. They also had a water/fuel seperator. It was rated at 85 hp 165 ft/lbs of torque.
Olds had a diesel 4.3L V6. Chevy had a gas 4.3L V6 with TBI, sorta 3/4 of a SBC 350 block, no relation to any Olds motor. Your Elky no doubt has the Chevy.
I had an 1983 (2 door) Cutlass Supreme RWD with 4.3L V6 Diesel engine which was actually a great car, served me well for a daily driver for the 3yrs I had it. Lent it to a family member one time who filled the gas tank with gasoline, and that was the end of that. I swapped in a 350 Olds gas engine, and my sister drove it for many more years after that.
