I just bought a 1986 Cadillac DeVille roadster, creme yellow with navy blue interior and canvas top, with real Cadillac chrome wire wheels. 84000 miles on the car.

I love the car and have had all the fluids changed, brakes and alignment were not needed, wheels turned and balanced. But the problem is the car leaks oil around the front of the engine, and today driving around the area, I could hear a ticking noise. What do I do, I know the valve cover gaskets need replacing, but do I need other things done to the engine to rebuild it? I don't know, I paid $2,000.00 for the car and about $600.00 so far for maintenance.

And where or what type of garage would I go to for the work, I'm in Sanford, Fl. Any help would be great.

I have the 1986 Cadillac Deville roadster, creme yellow with navy blue canvas roof, not knowing where to take the car for repair in Sanford, Fl. I found a garage that told me the car was in wonderful shape, needed new valve cover gaskets and a new radiator, that was all replaced and the car is wonderful; it gets 22 mpg on the highway, the car is wonderful, new headliner and tinted windows, she looks beautiful. I'm very happy to own her.

We live in Miami, Florida and my son has a 1987 Cadillac Deville Sedan. He bought it used from a friend's dad and it has been giving him problems - now he says it needs a new transmission. We really need to fix the car and would really appreciate if someone could recommend a good mechanic - possible that would him to pay in installments.. The car is in great shape on the outside - it has zero rust. You can contact us at vtulina@gmail.com. Thank you!

The ol' infamous 87 Caddy Deville with that 4.1 engine. I remembering it being nice riding, but the engine was giving troubles sometimes. Keep in mind this was when it was fairly new (2-7 years old, then traded for 95 Fleetwood). Yet for the people that mostly waited for a good used buy, they got themselves a good car. Maybe that is what I should've done. Waited for some poor chap to pour thousands into fixing all the trouble spots at low mileage, then wait till they get flustered and sell the car, and go on with a well repaired car that will run for ages. I'll think I'll do that on my next car. Wait till someone buys a car, drop 4-5 grand into it fixing everything, they sell it for a low price because they hate it so much, and then have a good car.

I have a 87 Cadillac Coup Deville. I love the car! I bought it off of an old lady who was the original owner. It is blue with the white vinyl top and cream leather interior. Yes it has the much disliked HT4100 motor. The lady had all service records and had everything done on time at the dealership and it runs more solid than any car I have ever owned. It is also the most comfortable.

It has 125,000 miles on it and it needs new brake pads, but that's not a problem. It's not a fast car like I've always had in the past but it rides smooth, and the gas mileage isn't bad. I'm a guy who tends to get new cars all the time and have owned 12 different cars and this is on my top 3 favorites.

If you get a chance to own one that has been taken care of, get it!

I need some advice. Someone is selling a 1987 Caddy DeVille for $9,000. The car has 19 thousand miles, with a Rolls Royce grille, and Cadillac rims. This price is outrageous, but what would be fair, given its age? Somebody help.

Got a great deal on '87 coupe with 113,000 miles. Had sat for a while, everyone afraid of "death rattle" and coolant leak... replaced water pump, and tada, no rattle, no leak. Kinda makes ya wonder!

I do ease this barge around, have no real complaints, some of the plastic trim stuff isn't holding up too well, and the 25 year old cassette player crapped out. Loving the luxury!

Hello: I have a chance to purchase a loaded 1987 Sedan Deville with 22,000 original miles. The car is pristine.

Seems like some people love the car, and some hate it because of the HT4100 from all the stuff I've read. At 62 I don't need to buy another headache. I know the man selling the car. He collects cars with low miles and like new condition, so I trust him. I just want a like new car for a soap box derby price. Any advice?

Thank you;

The RWD 4100's were the bad ones (1982-1985). FWD (1985-1987) were much improved and a lot faster. Personally I wouldn't pay any more than $7,000 for the car.

Good luck.

I have a 1987 Cadillac Eldorado. I have owned it for about 5 years.

During recent engine work I was told that it has an '88 4.5 V8 and not the 4.1. I never knew because it has the 4.1 air assembly. Then I was told the transmission is also from an '88 Eldo.

And it will give you a current code eo59 TCC related. The engine is problem free, starts and idles perfect, transmission has a problem at 38mph-43mph if at normal driving speeds. Now if I squeeze the throttle at 38mph and get past the problem zone, it drives great. Any answers?

I purchased a Lincoln, but it leaked oil badly. I found a product for approx. $20.00 that amazingly stopped a leak that was so bad you could see it leaking when the engine was running. Wish I could tell you the name of the product, but that was several years ago. Farmers use it to stop leaks in their farm machinery.
