My dad recently ran upon a bard yard full of collectors cars. One of the twelve cars was a '87 GN TTop car. It has been sitting outside exposed to the elements for several years now. Everything is there on the car., it has around 91.xxx miles. Owner says it was parked due to brake problems. It is fair shape, it will need to be restored to suit. I am looking at purchasing the car, can anyone chime in on value. Pics to follow! Thanks, and God bless!

WOW! Lots of work to be done there! How bad is the interior? From the looks of it, you will have your work cut out for you!

My car sat up for about 8-9 years, however it was closed up in a garage the whole time. So it took a small amount of work to get her going again, however it was so so worth it!

I'd say that your best plan of attack is to get her up and running first and foremost. You might check out the TurboBuick forum and look up "Spring Cleaning" as they have a nice write up there that spells out everything that you will need to get her done!

However, for a short list you will need all new belts, hoses, plugs, fuel pump, fuel and cooling system flush, all new fluids, and it'll probably need all new vacuum hoses as well. Although I probably should have, however I didn't keep tabs on mine. But, I would guess that it only cost me about $800 or $900 roughly to do the whole Spring Cleaning Regimen mentioned above. And I'd definitely say get her running first and then work on the cosmetics!

Oh and the first thing that I did was to pull all of the plugs and fill the cylinders with a mixture kroil and marvel mystery oil. And I did so even though I knew my car would not be locked up or the like. In that, I just wanted to lubricate the cylinders and all of that. On yours you might want to remove both valve covers and lubricate everything from the top down! JUST DON'T FORGET TO PULL THE PLUGS BACK OUT AND SPIN HER OVER A FEW TIMES BEFORE YOU TRY TO START THE CAR. In that, you will need to get all of the lube out of there before you do that. Lots of luck to you and post up some progress pics!!!

After 7 years I am now without a Buick Regal but I have some parts that could be useful to others. Before posting on Facebook group thought I'd give you all a shot at these:

2 steering wheels (stock, not GS) with buttons, from Essence trim so all button options - both in virtually new/very good condition, including the finish on buttons.
After market door handle cups, F and R,
1 set OEM floor mats with Regal on them,
1 set OEM floor mats with Avenir tag on the binding (very discreet)
1 set L & R New rocker panel covers for TourX (matt black plastic, never installed but kind of long so shipping might be pricey),
OEM TourX cross bars with keys, I bought used from owner who said he used them just a few time, I never had a chance to use them, they look pretty new
3D printed cell phone holder that was sold on Etsy for a while from forum member and the console tray from same vendor,
Canvasback full rear liner set for TourX with cargo flap - all black
2 OEM gauge clusters I removed when I swapped to GS cluster.
New gas pedal assembly (kept as spare, never had the issue)
New OEM Fuel door mechanism, newer design without electric lock

I'd prefer to bundle some of these if possible.. The big items like rocker covers and cross bars might be pricey to ship. Pickup or in Central Florida would be preferable.

PM me if interested

We all have those days where we just need a good laugh, so let’s get a dedicated discussion going for exactly that.

The rules are simple: If you see a picture, meme, or comic that makes you laugh, drop it here.
  • Keep it within the forum rules (let's keep the completely Not Safe For Work stuff out of here).
  • No politics or heavy drama - this is an escape from all of that!
  • Context is optional. Sometimes a weird photo with no explanation is the funniest part.
Let's see what you've got!

My fuel pump relay has burnt out twice in less then a week. What could be causing it to do that?

I had the same exact problem and Movedon is 100% right. It's the bracket on the back seat which applies pressure on the fuse box, in turn applying pressure on the fuel pump fuse burning them out. You have to cut a piece of the seat bracket off and be weary of having too much weight in that back driver side seat. I burnt 3 fuses in about 3 weeks, and it also almost fried the entire fuse box. I took the fuse box out, and opened it up (which was very difficult to do). There are these little metal clips that hold the prongs to each fuse, that was toast and corroded from the repeated frying of fuses, so I took one out of the good looking clips out of a cigarette lighter that I never used, and put that on the fuel pump fuse spot that was faulty. Those little tiny metal clips were impossible to get so I had to makeshift it. Never happened again..

Although now the car at 79k is blowing smoke out of the tailpipe and i'm worried I have a blown head gasket with misfire cylinder 3 and service stabilitrak codes... Long story short, this car is very poorly designed and I would sell it ASAP before some BS happens to you

This is all a VERY simple job to do. Had mine in and out in less than three minutes. What year is yours? Mainly meaning, what engine is in it? If a Northstar, the cylinder head bolt issue was MOSTLY fixed by the time it was in these. If is the 3.8, lower intake gaskets are common, and dead easy. If the 3.9...those are great engines. What colour is the smoke?

Sorry for the long read but I'm going to copy my original post for this to give you some background of exactly what is going on. Thank you for your time!

I'm trying to pinpoint a problem i'm having with my 2009 Buick Lucerne Super 4.6l Northstar V8. Recently it starts up rough and has cylinder 3 misfire code. Also throws a Service Stabilitrak message on and off, along with a check engine light, and white/grayish smoke out of the exhaust, more white than anything. I heard a faulty PCV valve can mimic signs of a blown head gasket. I changed the oil, no milkshake consistency or anything along those lines. Oil was about 2qts low even though it had "10%" oil life left. There has been no other signs of a blown head gasket minus the fact I can't seem to get the coolant levels correct after changing a thermostat a few months back. It clearly had air bubbles in the system because heat would blow cold until I revved it then it would come back hot. All of this being said I'm praying it's not a head gasket as the car only has 79k on it.

The check engine light and the service stablitrak message come on and off randomly, and after a few minutes of idling super rough it calms down and drives like normal. Also when I go to turn the car on for the first time, it starts to crank and cuts completely about 1 second in.. then turning the key off and back on it starts right up still idling super rough. The white smoke comes and goes randomly as I drive it, but always blows white smoke when it's idling rough.

My main questions are... Where the hell is the actual PCV valve, and can it really replicate signs of blown head gasket with signs of white smoke out of the tailpipe, and cylinder 3 misfires like I read online? I hear that the PCV system is inside of the intake manifold and there isn't just a valve you can replace. I'm lost with this car because there is hardly anything left that I can figure out to help me learn if my car is a tin can, or if it's still worth about 7k. PLEASE someone help me with some intricate opinions on what is really going on, PCV locations and systems (if it even has a valve), and what to do now.

Again as this is 2nd post, check the Cadillac DTS forum as they have more experience on the Northstar also have the vehicle scanned for codes both active and stored. #238 is the PCV hose and assume it's inside the intake manifold, beyond that I have no additional information.

Last fall I bought a 1998 Buick Century with only 57,000 miles from an old relative who rarely drove. The A/C and everything else worked perfectly last fall. But this spring I used the A/C and it wasn't blowing cold. I drove 10 miles home with the AC "on", and the second I get home and put it in park the radiator hose blew off soaking everything with coolant. I'm guessing the small pressure ripple caused the clamp to jump a tooth or something dumb) Nothing was broken, the top radiator hose simply popped off the engine barb. I refilled it and used the same hose, which was in perfect shape.

While trying to diagnose my A/C issues, I confirmed the fans DO turn on when I disconnect the coolant temp probe connector (ECU demands fans when it can't read the probe I've found out by testing). I jumpered the A/C clutch relay and it DOES engage the A/C compressor. The refrigerant has proper pressure (so not a leaked refrigerant issue). I cannot figure out why the ECU will not let the A/C system run. I even installed a new coolant temp sensor into the engine, no change.

The cooling fans never want to come on when the temp gauge goes over 50% (but temp never goes more than say 55% to red, (and evidently they don't come on until it is REALLY hot?), but the fans both work fine when the ECU demands them.

So I've been without A/C all summer. One time we accidentally left the A/C knob on "norm" for 20 minutes which heated up the antifreeze enough to cause a "low coolant" light to flash on the dash. I confirmed there was enough coolant, so I drained half, pulled the antifreeze level sensor, scrubbed the sensor prong itself (just a metal post) and reinstalled and refilled my coolant, burped it, went for a drive, and the low coolant light is ack on even though its full.

Another annoying quirk with this car is no trunk release, ONLY the keyfob button (never experienced that in any car, not even a glove box button). Also, when I push the door's LOCK switch, i have to hit it TWICE, it beeps once as if I have headlights on or something (I don't) and its warning me it doesn't want to lock on the first press... Is this normal behavior for this car?


I do NOT want to pay dealership prices to have this diagnosed, and am hoping someone here has more knowledge than I do, and have some input on my issues here relating to no A/C and heating up the coolant / false low level warnings. I thought I had scored a great condition car, but everything is spiraling down all of a sudden.

Diagnosing an HVAC system can be tricky. First, it requires the use of an HVAC manifold gauge set so you can read both the high side and low side pressures. Just because it has "enough" pressure on the low side does not mean that there is enough refrigerant in the system. Secondly, you need a Digital Multi-Meter (DMM) in order to measure voltages and perform resistance/continuity checks to make sure there are no broken wires, defective sensors, etc. Third, you will need electrical schematics for troubleshooting the electrical parts of the HVAC system. Finally, you will need a vacuum pump in order to pump down the system if you find that you have a leak or need to add refrigerant.

R134a systems are charged by weight of refrigerant and not by the pressures measured by the gauge set. The only accurate way to do that is to first evacuate the system, pull a vacuum for a certain period of time in order to ensure their are no leaks, and then recharge it by weight.

If you do not have a set of HVAC gauges, you can "rent" them from most any O'Reilly, AutoZone or Advance/Carquest auto parts store using their loaner specialty tool program. A decent DMM will cost you about $30. The schematics can be obtained for free from Free Car Service Manuals from LEMON Manuals. The vacuum pump can also be obtained for "free" from the various auto part stores.

You could have a bad relay, a bad pressure sensor, etc. Also helpful will be a diagnostic chart which can also be found in the service manuals from Free Car Service Manuals from LEMON Manuals.

Good Luck!

I have a meter and had already checked / verified every function of as much as I could think of, 100% of the fuse and relay box is functional, and the lemon guide many times doesn't have all that much information, such as the coolant level sensor. All it has is a single graphic showing it's (obvious) location, but no further information can be found on that system https://lemon-manuals.la/images/DM14Q313/gm110/539134051/ which doesn't help diagnose or test the BCM or why I'm getting this erroneous low coolant light.

I was hoping someone with experience on this specific model and issue may have already dealt with this issue. As its likely (hopefully) something really simple and dumb that is causing the PCM to not want to run the A/C system...

Also don't know why I have to hit the lock button two times (on the door) to get it to lock, the first press gives a single chime, 2nd press locks the car. I'd assume the chime is warning me of some situation that needs to be rectified (such as headlights left on but they aren't) but I've never owned a Buick in my life, and are not sure how this ecosystem works.
Edit: had to use Claude to tell me this door chime thing is normal for Buicks, warning me that my driver door is ajar (duh, im exiting my car and about to leave, wanting to lock everything). I've never had a car act so silly (complaining about a driver door ajar as you are locking to leave it). I had been using Gemini as an assist but it was clueless about this "feature".

Still looking for a solution to replacing the balancer bolt for a 2005 Buick Century 3.1L SE. I've ordered an ARP 120-2501 balancer bolt (says it fits this car) but I'm out of other options. If this doesn't fit, what other options are there?

Here is a link to a Grade 10.9 M12x1.5x45 bolt -


While it is not TTY, it should be strong enough for your application.

Or, you can order ARP M12x1.5x45 bolts from Summit Racing - https://www.summitracing.com/parts/arp-664-1005?seid=srese1

I think this is the best alternative. I have heard very little negative stuff about ARP, and there is a decent chance the replacement will not be TTY. A re-useable replacement would be ideal in either case. I don't do wrench work professionally anymore except for myself these days. I do deal in obsolete auto parts though.

I do know that at the dealership near by, they reuse those bolts for what it is worth. I also know I have reused them too at our shop with no issue, not to say that it can't happen. All things are possible. However, if a ARP replacement can be found, then that is great. The 3.1L was a very heavily used engine across GMs lineup for several decades, the possibility of there not being a single option makes very little sense. I know that engine was used through and may have been phased out just after the 2005 model year, which I think was the last year before it was replaced by the 3.4L. I think, it's been a minute. All that said, there were millions of those engines and it's variants floating around world wide.

If Dorman does not have one, then making a plea to ARP to produce one specifically for the 3.1L with torque specs should be considered and may take the community to back a representative or just flood their inbox.

Yes, two separate threads because I hadn't gotten responses until recently - for which I'm thankful, BTW.
Re-using the existing bolt is certainly a possibility, one which I'm not ruling out but it's not a slam-dunk to go that route as there is plenty of opinion out there to NOT do that.
I am heartened, however, in the number of people who have re-used the bolt seemingly without issue but I'm also hedging my bets by ordering ARP bolts just in case. The real issue is that the manufacturer has stopped making the bolt itself, with every balancer out there ships without the bolt - which just seems asinine.

I didn't miss that part. The first line was me agreeing with you on the ARP bolt. ARP has a bolt that is for a Harmonic Balancer on a Ford that matches the specs exactly of the one for a 3.1L, btw.
