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 A Bad / Blown Head Gasket 3400 GM Overheats Thermostat Intake Manifold No Heat 3.4
Tried bleeding the air from your 3400 GM engine and it still overheats? Bad news. May be the head gasket or lower intake manifold gasket. Here are a few checks you can perform to find out where the problem may be.
Signs of a bad intake manifold gasket. Leaking antifreeze behind the power steering pump or by the water neck / thermostat housing. Out the sides of the intake gasket. Milky oil, water coming inside the crankcase mixing with the oil turning it into a milkshake.
Signs of a bad head gasket. You pull the radiator cap off when cold, you rev up the engine and fluid shoots out the neck with force. Exhaust gases pressurizing the coolant. Also a tell tale sign is while the engine is running the overflow bubbles consistently. Try and bleed the air out with the bleeder. You get fluid coming out and tighten it back down. Soon after you lose heat inside and need to bleed the air out again. After the car has warmed up and shut off, you hear a hissing noise. From the coolant or gasses coming out then will slowly hiss quiet until the pressure is relieved.
Can't go over every scenario. Just ask questions here and we'll see about finding out the solution.

How to Test Head Gasket
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.

About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give do-it-yourselfers basic instructions on proper vehicle repair and maintenance. All of our videos show real repairs being performed on real vehicles by real technicians in a real auto shop. (Repairs are filmed and shown with the permission of the vehicles' owners.) Although there may be more than one way to perform any particular repair (and in many cases there are lots of ways!) we try to focus on the methods that will be safest and most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex or dangerous for DIY, or require specialized tooling, expertise, equipment, and/or certifications. Those episodes will highlight the importance of hiring a professional auto technician for tasks that are not DIY-friendly, and demonstrate why such tasks are best left to professionals.

How To Fix Alternator Whine Or Belt Squeal Engine Noise Caused By PVC Gasket: GM 3800 Engine
Fix details explained in video audio on persistent squeaking fix for a GM L36 3800 Series II Engine; this is a 1997 Pontiac Bonneville.
I thought it was first an alternator bearing, then a serpentine belt, and then finally found a note on a GM site about PVC gasket. The PVC gasket was the problem.
If I didn't find that note, I'd still be messing with this problem. So just want to pass the word along out there and explain the background in case you have a similar squeaking L36 engine.
On other sites, many folks detail replacing pulleys and belts, on squeaking issues on this engine and still having noise problems. It isn't obvious that it is the PVC gasket.
In this case the PVC gasket was bad; it was rotted out as being 15 years old. This was a very frustrating problem and I thought this car was ready for the junkyard!
It was tough to isolate the squeak, for some time, because of the location of the PVC in proximity to the belts and alternator. Plus it happened mostly after the car was fully warmed up and after running on the highway.
It sounded like one of the engine bearings was perhaps worn out, the squeak progressively became worse after the car fully warmed up on the highway. It now makes sense because pressure was escaping from the PVC area and this pressure increased particularly after the engine was running at highway speeds.
When the car first starts, the squeak was not very pronounced which lead me to believe that as the issue occurred mainly as the car warmed up only, a belt or alternator bearing was going bad after heating up.
Turns out as detailed on video explanation, the PVC gasket had rotted out (original in car I believe), and since air can get through the now missing PVC gasket, the manifold pressurizes, and the squeak is (I am suspecting) air releasing from the MAP sensor housing through PVC gasket area.
Hope this helps someone out there that has a persistent L36 GM Engine squeaking issue, this engine very common on Chevrolet, Pontiac, Buick, Oldsmobile in mid 90s/early 2000s.
The kit mentioned at the end of the video is also online as "Dorman 47033 PCV Valve" kit.
