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.





Chevy 3.8L Upper + Lower Intake Manifold Gasket and Tensioner Replacement Part 2
Here is how to remove and replace the upper and lower intake manifolds and gaskets on a 2005 chevy monte carlo with a 3.8L engine. This procedure should be the same for any GM made vehicle with the 3.8L 3800 series engine like the Buick Lesabre, Chevy Impala etc.

Problem was not a head gasket. It was the lower intake gasket. But while the engine is tore apart figured I'd go ahead and rebuild the upper end.





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 constraints. I found this site, and it was very helpful. The guy has been generous to detail his projects. http://www.handymanlyness.com/archives/auto/repair/cooling_system/index.htm l .... 92 minute estimated upload time for a 5 minute video...
