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 =)

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.

This is a quick how to remove the Intake Manifold from a GM 3.8 series 2
Chevy 3.8 coolant leak
Yes, many of the 3.8 engines have leaking intake gaskets. But sometimes
it's not the intake gasket but the coolant bypass tubes instead. It's very
easy to overlook this. Here's what to look for and how to do it.
Removing the engine on my 97 Riviera
Pulling the knocking 3800 supercharged out of my Riviera to make way for
the replacement engine. Came out relatively easy thanks to the engine
wiring for the most part is one harness that unplugs at the firewall.
Everything is in that harness except the starter, alternator and speed
sensor wiring. The AC compressor and power steering pump unbolt and can be
left in the car so you don't have to drain the fluid/refrigerant. The
biggest pain was getting the axis motor mount off, the bolts were pretty
rusty. The ironic part is those bolts have to be removed to change the
belts, which are so cracked and chipped I wouldn't doubt they are original.
The old engine will either be used for parts, or I may rebuild it at some
1999 Bonneville SLE with L26 manifold
L26 UIM swapped onto an L36.
A friend and I spent some quality engine modding time. We swapped out the
lower intake manifold for a ported and polished one, and the upper intake
manifold is now the aluminum version from the Series 3 3800. There is a
custom throttle body adapter plate with a Series 2 supercharged 3800
throttle body. Rice pipe to conical K&N air filter make up the rest of the
air intake. Everything else is stock.

Just some nuggets of wisdom for fixing a leaking lower intake gasket on a

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

Demonstrated on a 2004 Buick Century 3.1L V6 FWD.
In this video, we demonstrate how to perform an intake manifold gasket
replacement on a front-wheel-drive 3.1L V6 engine, in this case in a 2004
Buick Century. This is a common point of failure on General Motors' 3.1L,
3.4L, and 3.8L V6 engines, which are used in a large number of passenger
cars across most of GM's model lines.

"Fix It Right!" is a series of how-to videos intended to give
do-it-yourselfers basic instructions on proper vehicle repair and
maintenance. All of our videos show real repairs being performed on real
vehicles by real technicians in a real auto shop. (Repairs are filmed and
shown with the permission of the vehicles' owners.) Although there may be
more than one way to perform any particular repair (and in many cases there
are lots of ways!) we try to focus on the methods that will be safest and
most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex
or dangerous for DIY, or require specialized tooling, expertise, equipment,
and/or certifications. Those episodes will highlight the importance of
hiring a professional auto technician for tasks that are not DIY-friendly,
and demonstrate why such tasks are best left to professionals.

Pontiac Bonneville 3800 Tune Port Injection Series I (Plastic intake leak solution).
In this video we explain how and why the plastic plenum on a engine will
leak. this video discuss the intake plenum on a 3800 3.8L engine from
Replacing the plastic plenum (intake) manifold (Buick 3.8) with a metal
(OEM) one from GM. The metal plenum can be found on most Oldsmobile with
the 3800 TPI engine.The plastic intake plenum are more likely to leak air
or coolant into the induction system. Coolant leaking into the cylinder
will cause the engine to Hydro lock (damage). when the plastic intake leak
air. it will cause a Lean condition. A leaky intake manifold will also
affect the O2 (oxygen) sensor performance by contaminating the sensor. An
intake leak will display many codes. replacing the sensor recommend by the
scan tool will not fix the condition if the plenum continue to leaks.

L36 to L26 3800 V6 Upper intake swap part 1
I got sick of that crappy plastic intake leaking so I decided to swap it
for a L26 Series III upper intake. This video covers modifications to the
throttle body. More to come.
GM 3800 Series II Supercharged Intake Manifold Leaks
This is an all too common problem with supercharged 3800 series engines.
GM used a plastic lower intake manifold gasket that would break down over
time causing coolant to leak into the oil. If left unfixed, it would get
worse to the point where your engine starts knocking from poor lubrication.
Your oil will look really milky as a result. This engine had only 60k
miles on it when I replaced these gaskets and its a good thing I did. GM
makes a newer revision aluminum gasket set that fixes this problem. You
can get those from a GM dealer, they are the set that has locating pins,
the stock ones did not, but these do fit fine.
