Just a short video of my engine partially taken apart.
I had to change the intake gasket.
This was actually my first time tackling a job like this and it was actually really easy.
So if you have a 3800 engine and need the lower gasket replaced do it yourself and don't pay the dealer. I was a total noob at it and pulled it off just fine =)
While it was apart I went ahead and installed an Intercooler.
I figure since its already apart an Intercooler would be easy to put in at this point =)
How to change a thermostat on a GM 3800, the fastest way
This is the way I like to change the thermostats on the 3.8 liter engines.
The main difference is how I manage getting the cooling system "drained" to
swap it out. It saves quite a bit of time.
This applies to any GM 3.8 L / 3800 Series I II III (One, Two, or Three) 1,
2, or 3.
L36, L26, L67, L32
Common vehicles with the 3800:
Pontiac: Grand Prix, Bonneville, Firebird
Chevy/Chevrolet: Impala, Monte Carlo, Camaro
Buick: Regal, LeSabre, Park Ave, Century, Riviera, Reatta

GM 3.8 Intake Manifold replacement. Removal the fast way WITH NOTES
this is the "Flat Rate " way to do a 3.8 liter upper and lower intake
manifold set. as you see it is not necessary to take off he serp belt,
alternator or tensioner assembly to remove the lower manifold. I recomend
having someone help when it is time to reinstall the manifold because it
can be tricky to lien up the coolant elbow and not mess up the lower
gaskets when reinstalling. Note that it is recomended to disconnect the
negative battery cable when doing any major repairs. This video is just to
show some guys that said that a lower manifold cant be pulled in way less
than 20 minutes, I know that I went over that , but I had some stuborn
injectors and Im a little out of practice. If you are going to do this
yourself and you are not a professional I recomend that you follow the
procedure in a service manual

Here is a longer video of the 1990 Buick Lesabre with major engine trouble.
Hopefully this can be of use if someone can definatively identify the
issue so that others who have a similar situation know what is going on
with their engine. As for me, I know this engine is trashed. A new one
will be arriving soon for the amount of $150 :)

HELP! Engine Knocking Noise 3800 Series II
Can anyone confirm this noise? Happened after a 2 hour highway trip. Oil
and Filter change the day before, and Lower Intake Manifold Gasket replaced
about a week prior. It did at one point seize the engine, however a couple
of days later it turned over with plugs removed, and fired up fine right
after they were placed back in. Still making this same noise, as it did
before it locked up. 240,000 KM on the car and engine.

Support 3800 vendors. I dont work for any of these guys but without them a
lot of us wouldnt be able to mod. Our cars are not supported by the big
aftermarket companies so heres a quick plug for the 3 vendors left.
2000 Grand Prix GT 3800 Series 2 Head Gasket Problem.
Ok update: The problem was a cracked lower intake manifold. Surprisingly
the upper intake was fine. The EGR passage wasnt in bad shape at all. It
was still sealed. But the lower intake was sucking oil and water in the
