Replacing Chevrolet Lower Intake Manifold Gasket
New intake gaskets on a 1997 Malibu LS 3100 motor. This is a very common
issue with these cars. In this video I take you though the whole process
not in a professional shop but in a drive way so you can get a realistic
look at whether or not this fix is for you.
Make sure you get the steel replacement gaskets as that will solve any
future leaking issues.
HOW TO CHANGE THE SUPERCHARGER OIL ON A GM 3800 SERIES II V6
just a quick instructional video of how to properly change the Supercharger oil on your 3800... some people say
just to re-top off your Supercharger,
but many owners as well as a good number of master mechanics ive talked to
about it that worked on these cars, they say to full out replace it by
draining it and putting new oil in, simply because if you know anything
about oil youd know that it breaks down over time especially because of
heat and friction. new oil handles it better and keeps it properly
lubricated and cooler temperature. old oil will be dirty, maybe burned,
and possibly ineffective if broken down enough over time. which method you
trust is up to you, im not saying either method is right or wrong, this one
just makes more sense to me, therefore thats the one i do on my car so we
made the instructional video for this, if you choose simply to top off your
oil, do all the same steps just dont empty the old oil first.
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
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.
#15) $2 MAF Enhancer
Adding resistance to the signal wire of a voltage-based MAF sensor such as
this hot-film type leans out the mixture. Unfortunately, the added voltage
increases as the RPM insreases-but if you start low it doesn't go too high.
It works for the same reason that MAP enhancers sometimes don't: because
there's a voltage/current coming from both sides- i.e. from both the ECU
and the sensor.

Buick 3800 Bearings or Lifter or Rod Knocking with Valve Covers Off
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
with their engine. As for me, I know this engine is trashed. A new one
will be arriving soon for the amount of $150 :)
