everyone talks bad about these engine, just gotta give it some love, replaced the head bolts and main bolts with ARP studs so that it can handle the compression properly and not blow a head gasket or lift the heads. and add a water separator then your good to go.
Not worth it to most people. Way too much money to do all that, for what. 200hp maybe? If you're into it, God bless but most people turn their heads. In a video like this, it's more intriguing to the viewer to actually see one up and running, and somewhat reliable.
It’s funny how people badmouth these by the time they quit making them they actually had most of the problems fixed but no one would buy them after that.but look at how many people buy 6.0 L power stroke’s now those are money pits. My friend has a fleet of power strokes on his farm most of them bullet proofed But still they’re not cost-effective when do you consider a couple of repair bills cost more than what he paid for the trucks with under 100,000 miles on them.Maintaining one of these is pennies in the bucket compared to a 6.0 power stroke Granted the power stroke has a lot more power but still not nearly as cool as one of these old 5.7’s. I know a guy that has a 85 Chevy truck with a 6.2 It has over 500,000 miles on it other than routine maintenance it’s had a clutch The fuel pump rebuilt and one set of heads put on it. Not bad for a motor people consider to be junk. Water in the fuel killed more of these than anything. They didn’t have a very good fuel system and the fuel was really crappy back then.
@@SH00T_TH3PUMP Spend less money than you would on a modern diesel and it's probably gonna be more reliable. And 200hp is plenty. I can keep up with modern traffic at 75-80 on just 90hp...
yah I kinda want one too, just put it in a 4-door sedan with a wide ratio 4-speed manual and 2.73 rear gears let the big dog just eat miles like candy.
@@isaakwelch3451 it’s a straight piped N/A v8 diesel. They all sound pretty similar to each other. I think the best sounding one is the 7.3 idi mainly because it’s displacement
Update: The Olds is still running like a champ, I put 30,000 miles on the car since I posted the video. Pump has been turned up all the way for two years now and I can get it up to 99 mph before it starts to govern out at 3850 rpm, all original head bolts and head gaskets. I have zero issues keeping up with traffic, the guy behind me will literally dissappear in a cloud of thick black smoke. I do notice the fuel filters are plugging up around 1000 miles or so, you can take them up to 2000 miles but the injection pump wants more fuel than the transfer pump can pull through the filter. I still change the engine oil at 2000 miles and use Rotella 15W-40.
I’m late but since 1981 the 5.7 was a really reliable engine, Detroit fixed the design problems and made this engine bulletproof. All the cars received this version of the engine in 1981, but not the trucks, which still had the same version until the 6.2 was launched.
My dairy farmer neighbor bought the first new one I ever saw. It was the light metallic green and he loved the car which he drove about 15 years. He said it got 34 miles to the gallon going to the beach, about 185 miles one way.
Something about us dairy farmers and these diesels, I guess we like them! I can get 27 mpg on a nice straight level highway with no wind, usually when I drive out to South Dakota on Minnesota state highway 28.
Impressive performance for a 5.7 liter Oldsmobile diesel V-8! A very clean running motor. I remember a black cloud of soot following a vehicle with a Oldsmobile diesel V-8 when they were new.
My dad was a master mechanic , only guy around years ago that could rebuild the pumps . I have 8 in garage and I don’t know who would be interested in them , ? I miss these old Diesel engines ! I used to go to school getting 35mpg and burning what was called at the pumps ( Fuel Oil ) cheap stuff . Ran fine
Everyone says these engines are so fragile, yet I've put mine through the ringer with no issues. Most gutless engine I've ran, but I really enjoy the mpg.
Yes. These folks started in the 1920’s and worked into owning over a thousand acres by the late 1970’s. We pulled bailed hay with an old 49 Chevy 3100 on four wheel wagons. The old truck had brakes on the right front wheel only. Early on much of the equipment and tractors was patched up hand me downs others had worn out. That was the first new car he ever had and he was in his fifties. By the 1980’s times were good with a new milk parlor, good tractors and implements.
I put straight pipes on two of my 5.7L Diesel cars. One was an '81 Chevy caprice & the other was an '81 Buick Riviera. They were both Goodwrench DX replacements.
Sounds fantastic. I have a dissambled 350dx engine that I got when a bought an old truck. Can you recommend any literature or service/repair manuals on how to rebuild this engine. If so , thank you in advance. Eugene
I'm reading through the comments and wondering why so many people are making reference to the 6.2 diesel of the same era? The Oldsmobile 5.7 and Detroit diesel 6.2 were completely unrelated and met completely different fates. Not seeing the connection
Hey Matt, I have one of these motors that I'm putting in an old Toyota celica. I've so far not been able to get it to crank over fast enough to start, so was hoping you could tell me what cca your battery or batteries are. Any help would be rad. Im hoping to get mine to sound like yours does! So rad!
Wiggy McDoll Thanks man! That sounds like a neat project and very unique also. This car of mine has two 12 volt 650 CCA batteries. Make sure that it's not the pump that has the problem and by that I mean to make sure the plungers aren't stuck in their bores from setting around too long. If you get smoke when cranking then it's not the pump.
DeputyFuttBuck I wouldn't say its worthless. This has been my daily driver for the last 10 years and I have had one problem with this 350. 30 mpg in this boat is pretty nice.
@@mattlf9120 You probably have one of the last running. GM fixed all the issues before the end of its run, but the image was so damaged by the first couple of years it was offered they never recovered. Even the new diesels of today (think Chevy Cruize diesel) never sold as of late - and now that car is discontinued.
DeputyFuttBuck Like you I too also always thought these oil burners were worthless without any experience with them.But after decades at car meets I've stumbled upon 2(!) people who had ZIP problems with the diesel Olds.Both were retired taxi drivers and utilized them in cabs.Independently they told me their use of heavy duty diesel spec Cat oil and drainable water separating fuel filter kept their Olds diesels alive for 100k's of miles
@@localsheriff Sounds about right. One of the major changes after the first couple of years of production is that they added water separating fuel filtering systems so the engines did not fail like the first model years did. They enhanced the cooling to prevent overheating and reinforced the failing engine gasket in addition. This took care of the three major issues of the initial design and only then was it a relatively reliable engine. They really had a lot of issues when they rushed it to production initially. One of the worst engines ever initially.
If by worthless you mean cheap to purchase then yes. I picked up a clean bonneville with the diesel for $700. If you mean terrible engine, not really. They arent fast but they're a lot better than people seem to remember.
What happens when you take a 350 Rocket and make it diesel? Broken head bolts, that's what! You also get good sound though. Replace the bolts with a good set of studs and you're golden.
I'm already golden, head bolts and gaskets are original to this engine, pumps turned up all the way, plus I put 10,000 miles on it this last summer alone.
I do, I've had it up to 4500 rpm a couple of times since. They sound like a big ass big block at that rpm, glorious sound. I think the dual exhaust helps the most.

They can scoot pretty good, you need dual exhaust and the pump turned up, getting the rpm's up in the top end, you really notice it.

how's it running today do you still have the car
Yep, I still have it, I drove it out to South Dakota a couple of times this winter, it's running great!

To be fair they're both GM diesel V8's
They’re both naturally aspirated GM diesel V8s from roughly the same era and sound almost exactly the same?
Do you still have the car ? If so, could you do a start up video.
Like a cold start?
With the camera in the same position?
wondering if a Olds 5.7 diesel could replace a 455 Olds engine?
It'll bolt right in.
You should do a video of wide open acceleration
I'd love to, 4,000 rpm it sounds just like a big block Chevy.
Did these have good internals /blocks at least? Would be fun to bullet proof one and turbo it
They were pretty strong stock.
Will probably need work if you turbo one.
