The 5.0 Liter V8 was either a Chevy or an Olds motor, Cadillac never made a 5.0 Liter.

That is right. The 5.0 does not belong to the Caddy. My 1991 Gold plated D' Elagance is still the finest caddy around. 135000 miles, I don't think it will ever fail me.

The 5.0L in the Cadillac has to be a Chevrolet block. Oldsmobile only made one V-8 block size to accomodate their 4.3L V-8 (260cid), 5.0L (350cid), 6.7L (403), and 7.5L (455cid). The Olds block is huge, roughly the size of a 396/427/454 Chevy block, with smaller heads. You have to have the smaller Chevy block to stuff into a Cadillac.

Okay THE 5.0 is a oldsmobile V8. Its displacement is 307 Ci's.

The 5L was a carbureted Oldsmobile engine in 1990 and was changed to a fuel injected Chevy engine for 1991. The 5.7L was the fuel injected in 1990, but gained a performance boost for '91.

Just to let you know, we had to replace the 5.0 liter engine in our 91 Brougham due to shop tech making an error. It was replaced with a 5.7 liter. We were advised the 5.0 liter and 5.7 liter are both Chevrolet engines. We have 124,500 miles on the car in total, with 34,500 on the new engine. Up until the mechanic damaging the 5.0 liter, we did not have any trouble with it at all. However, we are enjoying the extra power the 5.7 liter has since the car weighs as much as it does. The car looks and rides great. Our only complaint is the wind noise around the front doors. We have replaced the rubber, but it still is pretty apparent.

In the 1990 there were three engines available. A 5.0L Chevrolet TBI Fuel Injection, which was apparently a 170 HP engine. A 5.0L Oldsmobile (the same 307 that was in the 1980s Caprice Classics) which was rated at 140 HP and a 5.7L Chevrolet TBI, which was 175 HP.

Although the two Chevy engines were more powerful, the Olds 307 is the most reliable engine I've come across.

In 1990 there were only 2 engines a 5L and a 5.7L. There was only one 5L and that was the Oldsmobile one. They didn't use the Chevy one until 1991.

My parent's bought a Brougham D'Elegance in 1991. I helped them buy it at the time. My father passed away in 1998 and my mom is now thinking of selling it. As a widow on a fixed income, the gas is killing her.

At one time I thought I would inherit the car from her, but I now live out of state and it's not practical for me to assume this car from her.

The car has LITERALLY 41,400 miles. This is not a lie. 41,500 that can be certified I'm sure.

It's white with the gold trim, with True Spoke wheels. It used to have vogue tires as well, but we needed to replace them as they were cracking.

The car is used every day by my mom, but for the first several years of ownership, it would get stored in the winter. She can't afford to keep two cars, so it's now her daily driver (which isn't far).

She wants to get a smaller car that gets better mileage. I've done the KBB research, so I know what it shows, but I'm wondering what someone would be willing to pay for the car.

More info:

5.0L V8

Gold trim

True Spoke wheels

Body is solid. A little rust bubble is starting to form on the rocker panel trim on the left fron quarter panel. That's it!

Interior is in perfect shape. No rips, tears or cracking (41K miles!!)

Vinyl top has no rips, tears or cracks.

A forum like eBay or Autotrader would be a much more appropriate site for a listing like this. This site is for reviewing, not selling cars.

1st Mar 2008, 14:07

I wasn't trying to sell the car. I just wanted to get an idea of market price.

That's what Kelley Blue Book is for. They are experts in the field.

I recently test drove the 1991 Caddy Brougham and it drove so smooth. It has a crankcase seal leak, does anybody know how much that would cost?

17th May 2009, 20:57

I just got a '91 de'Elegance from an older woman. It was always garaged til I brought it home, then it rain for days... I found water under the mat in my trunk and under my passengers left foot, I have a vinyl top and it's in great condition. Does anyone know how this leak can be fixed? My main trunk seal is not leaking. Could it be the top?

21st May 2009, 08:09

The water on your passenger floor is more than likely coming from a leaking windshield. I have the same problem on my 92. Not sure about your trunk though... probably getting in from the rear window.

These Cadillacs are a disgrace to the wreath and crest. They stopped making them because Lincoln was whoopin their butt. But besides that, they haven't made a real Cadillac since 1976.

And for any of you youngins that want to debate this, go buy a 1960 or early 70s Cadillac. That's when they were real and could melt the tires off of the rims.

My wife is a Lincoln fanatic, and I have to agree with her on one point, Lincolns definitely ride way superior to Cadillacs.

Have fun with all of your cars. I'll stay with my 71 Fleetwood series 75 limo.

Riding in a 1991 Caddy Brougham is like sitting in your favorite couch and relaxing. Just looking out the windows and enjoying the views. Great!!!

23rd Sep 2010, 09:22


Why would you want to "melt the tires off a Cadillac"? I mean, it's a Cadillac?!

23rd Sep 2010, 10:32

The leak could also be coming from a small rust hole in the firewall or clogged upper water drain. Check for leaves and other debris.

I have had problems with this car myself as well.

2nd Nov 2010, 18:59

I'll stick with driving something that gets more than 10 MPG.

The Cadillac Brougham was Cadillac's best road car. My Aunt had a 85 Brougham coupe; it was triple dark blue cloth interior, it was a sweet looking car. She has a black 91 Brougham; it is a beautiful car. It would be nice if Cadillac did bring this car back, instead of the stuff they are putting out now.

I just had this situation. My boss has a 1991 Brougham d'Elegance black. On black gold trim, gorgeous. I was in love, and a tree just today fell on it. Just minor damage, and he gave it to me just like 5 hours ago, so I came to read about, and I am excited.

You are right in a way. These cars were carburated for the longest time, while Lincoln embraced EFI in 1980. Not only that, but Cadillac didn't do a good job on updating these cars throughout the 1980s. The body style became dated and the interior remained unchanged since 1977. GM also made the mistake of charging up the wazoo for one of these cars, while Lincoln's more advanced Town Car was priced more along the DeVille's range. That's why Lincoln was easily able to outsell Cadillac in 1988, and why the Brougham was never really able to stand up to Lincoln.

Don't get me wrong, these are still incredible cars. I own a 1985 Lincoln Town Car, and am thinking about buying a late-1980s Brougham to keep it company. I'm just stating the reasons why these cars eventually met their demise.
