So after a long search I was able to buy a stock 1987 GN with 23K miles on it. Here is my question, the car has been sitting for about 17 years. I have driven in about 10 miles since I bought it and I am planning on taking it to the dealer soon. It seems to be running good, other then having all the fluids changed and a general look over what services should I look at getting done right away......

I'm really excited about finding this car, I bought a 1987 T-Type right out of college and I have always wanted a true GN so this one will be staying with me for sure.

Thanks....
 
Just my opinion
I wouldn’t take it to a dealer
The techs there most likely have never put a wrench on these engines and most of the parts are discontinued from gm

Some one here will point you to the right place in your area

Location?
 
:arghh:STOP!!!!!!!!!!!DON'T TAKE IT TO THE DEALER!!!!!!!:eek:

Don't let them touch it! Don't let them look at it! Don't even drive past the place!

More info to follow.
 
Most Turbo Regal specific mechanics work on more of these cars in a single day then those monkeys at the dealership have ever seen in their entire lifetimes. The Turbo Buick community as a whole has reverse engineered every single mechanical and electrical component on every single square inch of the car. And that in itself is important, but to add even more, not only have we done this, but we also have an in depth understanding of the theory of operation of these components and where each one falls short of it's intended propose and for what reasons.

Thousands of different component failures seen on thousands of TRs combined, gives TR specific mechanics and backyard gurus the experience that no dealer mechanic on earth could ever hope to match. Furthermore, many of the members here on this forum are mechanics and some are actually college educated and experienced trained engineers.

I hope your truly convinced. Because I don't think anyone needs to add any further information in order for you to be so.
 
It would be well worth your time to take your car to Brian Lorenz Racing. He is a Turbo Buick specialist and will not steer you wrong . He's about 170 miles from you , but worth it .
 
Well you found this forum, that's half the battle.
 
Other than a TT chip, hotwire the fuel pump, and use a high zinc oil or zddp, I'd leave it bone stock and enjoy it. I miss my stock GN, it was trouble free, my T on the other hand, modified, and always being upgraded.
 
when i take my car to have exhaust work or any other thing i cannot do i tell them no one is to drive this ! period! the regular techs usually say only steve works on that car. better know the people at the shop or you may come to pick it up and get some bad news. john

I carried mine up to him (about 290 miles). well worth it. He got mine running very good.

Some have came much farther to him.

Also you can look him up on Facebook
 
The one time I took a GN that I do not have now to a dealer it was about 1992 and the car ended up having a bad chip although Buick did not find that out is was me that ended switching out another chip and curing the issue I was having. Anyway it went in full of fuel and returned with half a tank and a lot less tread on the rear tires. Never again. I was younger back then and stupid.

IMO, I would never take it to a dealer! Dealer wouldn't know what to do with it!
 
Its a million things one can do when he first gets his car and this is something that's not talked about often but when I got my car one of the first things we done was remove the intercooler and cleaned it out with gasoline , and believe it or not it was very grimy on the inside . But like I said its a million things to do BUT the main thing is to have FUN , Have a good weekend , post us some pics when you can . Its nice to see the low mile cars still out there . Keith
 
A few years back in late 90's or early 2000's, I met a guy at some Buick social event who told me his story about a dealer service department. I don't remember his name and for all I know he could be a forum member even to this day. But I somewhat remember his story.

And it goes a little something like this ...................

One day on his way to work his TR stalled just 1000 feet from a Buick/GMC dealership. It didn't stutter, it didn't stumble, it didn't even hiccup. It just died instantly. Many of us would instantly know what the problem is, and so did he.

He walked to the dealer and asked the service department to tow his vehicle from up the road. He explained his situation and exchanged information with them. He was in a jam and explained he needed to continue on with his day and would return at the end of the day to pick it up. He knew it would be a little costly to have them tow and service such a bullshit little item, but he just didn't have the time to deal with it. He told them to change the crank sensor. Called his wife and she drove him to work.

At the end of the day he returned. The service manager explained that it would be difficult to diagnose the problem because of unknown previous work that was done by others to the vehicle and that it is adding complexity to the problem . He once again explained that everything was as it should be and it was most likely the crank sensor. He asked them to change it again and said "It's a five minute job! And I'm willing to just pay you the full hour or 2 including the part cost and the tow fee! Please, I need my car back!" Life was in the way, and he explained he didn't have the time to do it himself.

For a few more days he played phone tag with the service manager and was told that they were still working on it and the sensor was changed and it wasn't the problem.

Finally, he was asked to come pick up his car. When he did he was hit with a bill exceeding somewhere over $1000 dollars. The Service manager explained that there were many problems that needed to be resolved and it was impossible for them to find the problem. But all was good now and ready to go. He flipped out! and asked about all the things they did.

Turns out, they removed his Caspers pump hot-wire kit, his voltage booster, his solid MAF pipe and K&N filter, returned his valve cover breather back to his turbo inlet, put stock plugs in at the factory spec gapping, threw away his Magnecor wires, disconnected the fish tank valve and replaced the vacuum line at the wastegate and maybe a few other things. He was told all of these things contributed to the "no start" issue. When he asked for his parts back, they were given to him from a garbage bin.

But the best part.....He obtained his crank sensor. And he could clearly see the severe damage caused by it taking a hit from the crank ring. This was the result of the owner himself admitting he had messed with it on his back in a dark garage while detailing and or servicing something else. He admitted he may have not have aligned it properly or tightened the slide locking bolt. This along with a general understanding of how these cars work gave him reason to believe it was the crank sensor right from the beginning.

He paid the bill and then immediately asked his credit card company to stop payment. Then he had a friend who was an attorney flood the dealership with never ending letters until the problem went away.

So in the end...........he stiffed them. And rightfully so.
