'96 Century general project thread

[LeftVentricle]

If its an aftermarket crank pulley, its probably the ring and not the sensor. It sounds like you have a bad computer too though, if it didn't throw any codes while the other one did. Glad you had a successful fishing trip on that injector clip

That is the 3rd PCM I've put in it. The original one wouldn't communicate with the emissions testing station's computer (that's a fail of the test), so I swapped the white wagon's original PCM (which passed). Now it's running the '97 PCM I got from Milzy, which works well enough. Not sure what it is about the '96 PCMs that suck so badly.

As for the crank sensor stuff, I don't know if the balancer was replaced prior to my acquisition of the car. I'll find that out later, I suppose, but as I said, I'm not terribly concerned at the moment.

Considering this at some point in the future.

Someone on the A-body forum did a write-up on making your own coilovers a while back, but the owner took the site down at the end of 2023 without any notice, and all of the years of knowledge stored there is gone.

I don't recall who originally did the coilover swap, but it left something to be desired. At one point, I did a bunch of research and came up with part numbers for everything that should have made for a real nice setup, but I never got around to doing it. Mitch (zalorian) did though, on Steve's 5-speed Celebrity and he did that nice tutorial thread. I'm betting that Mitch still has all the part numbers and sources saved.

I hate the 3300 engine.


HATE IT.


Well, hate is probably too strong. It has a couple good qualities.


Despite not having a balance shaft like the 3800, it runs pretty smooth.


And as I noted in a post from a few years ago, it gets phenomenal fuel economy on the highway, which I will be needing soon.


I will be taking another trip to Kansas in a month or so. 2500 miles of driving uses plenty of fuel. So I need this car to be road ready and running well.


Neither of the wagons are suitable at this time, for very different reasons. One is mechanical, one is clerical.


The yellow sedan has been sitting in the garage since mid-2021 with a seized starter. In addition to the images you're seeing, I finally got around to that. It is not a particularly fun task, but I would do it again a dozen times if it meant I wouldn't have to do THIS JOB.


Everything you see above is about 2.5 hours of TEARDOWN to get to the thermostat on this engine. It's stuck open, which is fine in the summer but not so much in the winter. It means it didn't have anything approaching effective heat, it ran in whatever loop it is when cold and drank gas, the torque converter wouldn't lock because the transmission was cold. All of which translate to a miserable highway trip. As a contrast, when I've done a thermostat on the wagons, which have an L82 and an LX9, I'm in and out in like 45 minutes. I'm REALLY not looking forward to putting this all back together.

To answer a potential question, yeah, it may have been "easier" to pull the throttle body instead, but that risks breaking all kinds of water and vacuum hoses and the TB gasket that are quite difficult to come by, since this variant of the Buick engine was only used for a few years, and not very widely.

In related news, I robbed the radiator from the yellow car a few months back to install in the black wagon when it started leaking. So I need a replacement. Public service announcement: as cool as they are generally, I do not recommend buying a radiator through Rock Auto.



That kind of damage to the plastic portion is annoying, but understandable. THIS BULLSHIT ON THE OTHER HAND



I cannot fathom how it could have been CUT like this. I didn't take a picture, but the other side had a cut like this as well. To their credit, Rock Auto issued me a refund quite quickly and so far hasn't asked for it to be returned. I may attempt to have it repaired, though that would exceed the cost of replacing it. I know what that cost is, because I still needed something to put in the yellow car. So I yanked the core from George.



This is what ~10 years in Las Vegas looks like. I took it to a nearby radiator repair shop (those still exist!) and $150 later, this is what I have.



They cleaned it (necessary after running straight water for several months in an iron block engine) and repaired a small leak. Ready to run for another ten years!

[SappySE107]

I think the radiator is supposed to cut like that for thermal expansion. Not saying its necessary, but I think it was done on purpose. The aluminum radiator cleaned up pretty good

[LeftVentricle]

The folks in my thread on Something Awful agree. I just have never seen that before, and I have purchased a few radiators in my time. I'm still not using it right now due to the damaged plastic, and I don't really need to repair it any time soon.

[LeftVentricle]

Unsurprisingly, after sitting for five years, the fuel pump in the yellow sedan was stone dead. I had two options: 1) pull the tank, clean out all the bad gas, install new pump. Good, but costs money and time. 2) pull tank from white wagon and slam it in. Great because it's free and known good. I'll let you guess which one I picked.

That was enough though. Starter, thermostat, and fuel pump got the old girl back on the road. New tires on the Malibu wheels, since those were 9 years old. We've never been more back, boys.


FUCK YOU BALTIMORE!

[LeftVentricle]

Alright boys, it's been a minute.

I don't have anything fun this time. I've been doing a lot of thinking about this fleet I've assembled, and some of it ain't good. Here's a list of what I have and what my tentative plans are.

1) 1996 Buick Century Special wagon "Greg"

This is the black wagon, which I have named Greg, since it's the opposite of George in a variety of ways: paint color, reliability, creature comforts. Powered by an L82. Once I get the title issue sorted*, I plan to swap my spare LX9 and rob George of the built transmission and do the swap correctly. That is, no janky ass wiring, retain air conditioning, performance parts installed, tuned. I may also swap over the tow hitch, but I'm still up in the air about that. The paint is terrible and I'm going to run with that: bedliner paint job. Fuck it.

2) 1992 Buick Century Special sedan "Goldilocks"

This is the yellow sedan, recently revived after five years of banishment to the garage. Motivation provided by an LG7 3.3L Buick engine and 4 speed auto. I plan to give this to one of my daughters once she obtains a driver's license, as that will help her in her career greatly. She plans to spend a lot of money on it to regain functional air conditioning (tl;dr AC failed completely some time in 2017, entire system rebuild necessary). A noble endeavor indeed.

3) 2004 Chevrolet Cavalier coupe

This pile of actual garbage was a gift from my uncle in 2020, who did not treat it well or maintain it in any meaningful way. Equipped with an L61 Ecotec and automatic. Heavy smoking means the carpet is roached, and a haphazard head gasket job ended in what I can only assume is a cracked block. It needs an engine, entire cooling system, carpet, front seats, tint, wheels, tires, probably brakes after sitting outside for five years. Classic basket case. I had considered giving this one to another of my daughters, but at this point I think I need to cut my losses and junk it. There are literally a million more just like it out there to start with a better base. If you feel like you want to take this trash heap on, feel free to PM me. I have a bunch of parts that will go with it too.

4) 2000 Chevrolet Silverado

I have not posted about this or the Cavalier because they're not 60v6. This truck belongs to my mother. It's an LS trim, LM7 (5.3L), auto, push button 4wd, extended cab, 6.5' bed. Ran when parked. It's been sitting for a couple years too. I believe its main issue is a misfire on #5. Also the driver's seat is destroyed. Typical GMT800 stuff. If anyone is interested in it, PM me. She's open to selling.

5) 1996 Buick Century Special wagon "George"

And now for the main event: the first documented LX9 swapped A-body. How the mighty have fallen. George has been further downgraded from Spot Of Shame to Exile In Garage, after the sedan triumphantly made its escape. Numerous are his foibles. In no particular order: coolant leak requiring replacement of lower intake manifold, power steering leak from an abraded hose, a wide assortment of electrical problems, none of the doors work correctly. I think it's time for George to rest. Revival at another date is still on the table, but even if I ignore the electrical and doors, I've robbed a lot from him to make Greg and Goldilocks run. After some long introspection and genuflection, I have decided that George will be "returned to stock", receiving Greg's L82 drivetrain and zero performance upgrades. I even have a set of factory 14 inch alloys that came with Greg to put on.

I wish I had another fun and wacky installment of Daniel And George's Wild Adventures, but that's not how life goes sometimes. Sometimes it just sucks.

*long story, PM if you want the details. I would rather not discuss publicly.
