Impala - Valve Cover Gasket Replacement (Front) 3800 Series II
This is how to replace the Front Valve Cover Gasket on the 2002 Chevy
Impala 3.8L (3800 Series II)
This is a fairly simple job, to do this you will need the following Tools:
1. Socket & Ratchet set including 10mm, 13mm, and 15mm
2. Valve Cover Gasket Replacement by Felpro ( Part Number: VS50080R) $14.99
3. RTV Black by Permatex (Part Number: 82180) (not necessary but nice to
4. Torque Wrench that reads Inch/Pounds NOT Foot pounds. Harbor Freight has
them for ($10-$15) (Harbor Freight Tools Part #2696) The one at harbor
freight is 1/4 drive so if you have a 3/8 inch socket set get a universal
adapter set for about $4.
5. Alcohol, acetone, or brake parts cleaner
6. Toothbrush to scrub the valve cover where the gasket will sit
This whole job can be done for less than $50 including the cost of the
torque wrench. I was quoted about $250 just to change the front valve cover
gasket by a local shop.

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

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.

How to Replace a Front Hub/Wheel Bearing: 2004 Pontiac Grand Prix
Here I show you how to replace the front non serviceable wheel bearing on
any similar front wheel drive application. The vehicle I'm working on is a
2004 Pontiac Grand Prix. This style wheel bearing is very common on many GM
front wheel drive applications and usually need replacement at 100k miles.
Common problems include a short developing in the wheel speed sensor, and
the grease drying up, causing play and eventually squealing.
