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.
Impala - Rear Valve Cover Gasket replacement (3800 Series II)
This is how you change the rear valve cover gasket on a Chevy Impala 3.8L
(3800 Series II). The method used in this video is WITHOUT taking off the
fuel rail and fuel injectors and plenum. This present a problem with a
tricky bolt that's next to the fuel injector. You don't necessarily save
time doing it this way as opposed to removing the Plenum and fuel
rail/injectors but it's less hassle if you're worried about seating the
injectors back into place and everything. It will take you some time to get
one of the 13mm bolts out that's next to the second injector in the back.
Also this method was attempting to get the valve cover off without removing
the alternator and tensioner assembly. There is not enough clearance to
lift the cover off without removing it. So go ahead and remove the
1. Disconnect Neg Terminal from the battery (8mm)
2. Remove the plastic cover by twisting off the oil cap piece
3. Remove the rear "brace bar" (black bar going from left to right) two
13mm on each side
4. Remove the Coolant Recovery tank and set aside (two 10mm nuts)
5. Remove the alternator
6. Remove the bracket holding the alternator to the engine by the fuel
injector (10mm I believe)
7. Remove the tensioner assembly (Three 15mm bolts, one of them is hidden)
8. Remove 6 valve cover bolts (10mm)
Follow in reverse order to re-assemble, use Permatex Medium blue loctite on
the the bolts for the valve cover, you can also change the grommets, but
it's not necessary. (They are only $10 for both front and back valve

How To Replace The Intake Tensioner Coolant Elbow 1992-99 Buick Lesabre
If you are slowly loosing coolant look at the passenger side of your engine
between the coils and alternator. You will see a small plastic elbow that
is prone to cracking and gasket or O ring failure. If your engine
antifreeze is leaking from this location you will need to replace your
coolant elbow. This video is applicable to the Buick LeSabre, years 92, 93,
94, 95, 96, 97, 98, and 99.
Engine Coolant Thermostat replacement 3800 V6 engine - Pontiac Bonneville P0128 OBD II Code repair
My check engine light came on in the fall of '09 so I had the code pulled.
It was P0128- Coolant Thermostat (Coolant Temperature Below Thermostat
Regulating Temperature). I decided to check and replace the thermostat. It
was the problem and has been fine since. Overall the job took about 45 min
to 1 hour including draining, warming the engine, and refilling the cooling
system. It was a pretty easy fix. This problem causes the engine to run too
cool because the thermostat is stuck open, causing more coolant to go
through the radiator than necessary. Ignoring this problem causes the fuel
mixture to be too rich, which will cause poor fuel economy.
Valve Cover Gasket Replacement Camry V6
Step by step procedure on replacing the front and rear valve cover gaskets
in a Toyota Camry with the 1MZ-FE 3.0L V6 engine.
Procedure is the same for V6 Toyota Camry, Avalon, Solara, Sienna,
Highlander, Lexus RX300 and ES300.
Also covered in this video: Spark plug wire and ignition coil replacement,
PCV valve and grommet replacement, throttle body cleaning and gasket
replacement, EGR replacement, intake plenum removal, spark plug tube seal
replacement, air filter replacement, coolant system drain.
The intake plenum must be removed to access the rear valve cover.
Good idea to replace spark plugs, spark plug wires, PCV valve and grommet
and EGR/ Throttle body / Intake plenum gasket while your at it.
The job isn't difficult, but its time consuming. Only basic hand-held tools
Use a torque wrench to tighten valve cover bolts.
Use washers to build up the height of crushed washers.
Use Permatex RTV on all sharp or uneven surfaces on the valve cover.
Refill cooling system with Toyota Long Life coolant and mix 50/50 ratio.
Clean the idle air control valve (IACV), throttle body, intake plenum and
EGR before re-assembling.
Have a friend hold up the rear wiring harness when removing or installing
the rear valve cover or tie it to the wipers.
Label all electrical and vacuum connections.
Freeze spark plug tube seals and use a heat gun to warm the valve cover
before pressing the seal in.

How to: Create Gaskets
In this video I show step by step how to trace, stamp and cut out gaskets.
The methods used in this video may not work in all situations. Some
modification to the process may be required to achieve the goal of making a
functioning gasket. In my case I was able to make all the gaskets I needed
by using the methods in this video.
I hope this video helps you.
Thanks for watching.
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
