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





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.

2006 Grand Prix Popping Noise Front End
I attempted to take a video here of the popping noise I am experiencing on the drivers side front end on my 2006 Grand Prix that has 62000 miles on it. Sorry for the quality of this video, it was windy out when I filmed this. I would really like to figure out what has gone bad. I'm thinking that it could be the strut or strut mount or possibly even a ball joint. This so called popping noise occurs when I am taking off from a complete stop, applying the brakes, or just driving down the road and I happen to hit a dip in the road. If you don't feel like listening to the whole video the times when you can hear the popping are at 0:42, 0:59, 1:53, 2:35, 2:38, 2:48, and 3:06. Any suggestions are appreciated!!





GM 3800 Series II Leak

Assembling modified Buick LN3 3800 Series I engine. Low-tension piston rings.
Assembling modified Buick LN3 3800 Series I engine. Low-tension piston rings. The entire rotating ammembly is together and torqued to specs. Even so, I can rotate the engine by hand (ONE hand, at that!) by turning the crank pulley. This is how a new engine should feel. The camera picks up well the sliding sound of the new pistons on the new cylinder bore. It is not really that loud! This engine is for an 89 LeSabre T. It has been modified. It has Series II 9.8:1 compression pistons (with low-tension rings); 252° Delta Cams modified roller camshaft; ported heads, inlet and Exhaust manifolds; and a re-tune of the ECM.





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 :)





400hp Grand Prix idle
Not all high horsepower 3800s have to be loud. This 340whp setup runs a stock Exhaust, stock manifolds, an engine that hasn't been cracked open, gets 28mpg on the expressway and even has luxuries like navigation and bluetooth. Whether you want loud and ostentatious or quiet and subdued we can get your 3800 set up.





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.
