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 =)

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

will be arriving soon for the amount of $150 :)

easy to overlook this. Here's what to look for and how to do it.

3800 V6 Upper Intake Swap Part 2-3
Got sick of leaking coolant so I replaced my VIN K 3800 plastic upper
intake swap with a metal one from a L26 3800 Series III (VIN 2) V6. Crappy
video quality, filmed at night. Will re-do tomorrow if there are
sufficient views to warrant it.

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.

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.
