How to Test Head Gasket
** Please see my other videos on this topic* Thx!
This video is intended for those who would like to know how to confirm a
damaged head gasket on a vehicle prior to making the decision to invest a
lot of money for repair. My apologies for the camera focus- next video I
will pay closer attention, but the information needed is viewable. Further
research should be done on the risks of overheating to the engine block and
such. This video is meant to simply show a 'how to' on the test method I
used quite often when professionally working on vehicles, the results of
which are based on chemistry and industry-standards of the time (1990's).
I hope you find this video useful. RI.
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.
Chevy Blazer Coolant Leak (Intake Manifold)
I have localized a coolant leak on my 2003 Chevy Blazer to the gasket of
the intake manifold (I hope that's the only leak..) Turns out that this is
common among this particular engine both in the v6 & v8 sizes. The
company's "mandatory" coolant "DexCool" apparently is caustic to the
gaskets and other parts of the cooling system. As a result a class action
lawsuit was filed against Chevrolet (I do not know the results).
The coolant system pressure test kit was rented from O'Reilly Auto
Parts. It required a $152 refundable deposit, but there are no time
I found this site, and it was very helpful. The guy has been generous to
detail his projects.
