Hello Sajeev,

This is my second time writing in about my Oldsmobile. I solved the cooling problem with a mechanical fan, however now I am having another problem. As you may recall I swapped in a ZZ4 GM Performance 350 CI motor, and now it will “diesel” for awhile after I shut it off. It only does this after it has had a chance to warm up. Do you have any ideas for fixing this?

Thanks,
Paul

Sajeev answers:

Dieseling is a common problem with carburetor equipped vehicles from yesteryear.  If you’ve owned a vehicle with one of these glorified toilet bowls for an extended period of time, odds are you’ve experienced this.  I did before, and I have again: our Ford Sierra project car and it’s 2BBL carb just dieseled last week!

Honestly, the five well-written causes for dieseling in the Wikipedia article (first sentence, paragraph above) does a pretty fantastic job addressing the issues.  I assume your Olds, like most not-totally-complete project cars, isn’t driven on a daily basis: meaning that carbon build up isn’t a concern. Perhaps the idle speed is too high. Since the ZZ4 has a fairly mild cam profile, keep it around 800rpm. Wikipedia also mentioned timing: make sure that ZZ4 is set to the correct specs (10 degree BTDC @ 800 rpm 32 degree total), but I doubt that’s the problem here.

The remaining problems are my concern, and they all point to the condition/tune of the carb.  How is the accelerator pump doing? Are its seals in tip-top shape?  Is the carb tuned too lean and still running a bit too hot? Fatten up the mixture a little and address any more cooling issues.  I hope you still don’t have cooling issues!

If the carb is some old pile you had lying around (or got for cheap) perhaps this is a good time to consider a stand-alone EFI swap.  Man, they are dirt cheap these days, and would really add the element of modern luxury to one of the nicer luxury rides of all time.  Of all time?

Don’t believe me?  Just go sit in a 9th generation Olds 98 Regency (or Buick Electra/Park Avenue cousin) and get back to me.  Plenty of old world Detroit luxury with a bit of modern production values stemming from the 1977 downsizing of these monsters. And introduction of gee-whiz tech goodies in the 1980s, natch.  These are just as nice as a Caddy without being ostentatious, and leagues ahead of any Panther. Oh yeah, I just said that: 1980s C-body for the win.

Send your queries to sajeev@thetruthaboutcars.com. Spare no details and ask for a speedy resolution if you’re in a hurry…but be realistic, and use your make/model specific forums instead of TTAC for more timely advice.

The Oldsmobile 98 was available for most of the 20th century, and the average swank level remained quite high throughout. Of course, there was a certain element of Simu-Swank™ as Oldsmobile’s core buyer demographic became older and the Malaise Era ground on. We’ve seen a few Ninety-Eight Regency Junkyard Finds, including this ’84 Regency and this ’94 Regency Elite, and today we’re going to look at a plush mid-70s Regency with Whorehouse Red interior and 210-horsepower 455-cubic-inch engine.
I went to high school in the early 1980s, and at that time this car was the most punk-rock vehicle you could own. Fill the rear package shelf with red-paint-splattered doll heads, slap some Exploited stickers on the bumper, and you were ready to go.
Let’s check out some of the luxury features, such as this classy door-pull bracket.
No comment.
Back then, Oldsmobile drivers smoked all the time. Actually, just about everybody smoked all the time, and they smoked in places like elevators, supermarkets, offices, and hospitals. Because you didn’t want to have to reach for a lighter to fire up your next Pall Mall, the Ninety-Eight Regency had a lighter-equipped ashtray in each corner of the passenger compartment.
I think I’m going to go back and buy these cool strap/interior-light setups for my van.
Even though my experience with Detroit-made junkyard clocks tells me that this clock stopped forever at 5:42 AM on April 19th, 1977, I’m going to bring a battery pack to the yard and test this one. If it works (ha, ha!) I’ll add it to my car-clock collection.
Not only is there fake woodgrain on the dash, there’s fake woodgrain on the knobs!
They don’t make ‘em like this anymore, which is probably a good thing. However, in spite of its faux-classiness and single-digit fuel economy, the Malaise Era Ninety-Eight was seriously comfortable for long highway drives. It was very quiet and had that floaty isolation from road harshness that octogenarians of a previous age came to expect as their right.

While it was possible to get a Ninety-Eight Regency Brougham in 1984, the buyer of this Olds cheaped out and went for the non-Brougham version. That just seems wrong.

When you’re talking about an Olds 98 from the 1980s, the conversation must turn to the greatest Oldsmobile song of all time. Suckers to the side! I know you hate my 98!
What we’ve got here is a big, traditional Detroit rear-drive sedan. By this time, the base engine in the Ninety-Eight was an Olds 307 making 140 horsepower, and the car weighed 3,886 pounds.
But Ninety-Eight Regency drivers weren’t looking for speed, in spite of what Chuck D said about his. They were looking for the same kind of luxury they got in their ’47 Oldsmobiles.
