The 3800 Series II in my recently purchased 2000 Buick LeSabre began to wet itself shortly after I purchased it. I love this car, but oh how my back aches after two days of bending over the engine.
The Buick 3.8L V6 engine is an amazing piece of engineering, refined over a period of 48 years. In all that time, one would think that these obviously talented folk could figure out a way to keep it from leaking coolant and oil at regular intervals. Alas, a rebuild of the upper and lower intake manifold is an inevitability with these vehicles.
There is nothing particularly difficult about performing this job. There are a ton of resources online to help, but it does take a fair amount of time to finish the job. The good news is that 36 hours after unplugging the first connector and removing the first bolt, she fired up in seconds and ran like a top.
And I only had one screw left over when we were done.
Thank you, Dad, for the use of a garage, and an extra pair of hands.
