How To Torque Cylinder Head Bolts - EricTheCarGuy
Well this was a fun one to make. I believe I covered everything but if you feel I haven't please let me know in the comments below as well as any tips you might have to add as well. I'm not trying to make a big deal about "pound feet" or "foot pounds" I'm just trying to put that out there, the important thing is that you get the proper torque and get the job done right in my opinion, what you decide to call it is up to you.

Part #8 FINAL Intake Leak 3800
Hope you enjoyed the series:
Parts replaced and items done while I had the chance:
Tensioner Pulley (even if it didn't need it)
Upper intake gasket with upper intake (Plenum)
Lower intake gaskets
All O-rings for fuel injecors
Gasket for thermostat
Top and Bottom radiator hoses and clamps
Spark plug wires
Cleaned throttle body
Cleaned and polished both motor mounts (aluminum)
Cleaned and painted the valve covers and gaskets
Used 200, 500, 1000, and 2000 grit sanding to prep
before painting any of the plastics
Port and Polished the Lower intake manifold
Changed the oil and filter
New heat shield hoses for all wiring
I took around 5-7 hours to do this repair. I took more time to video the process. I am not a shop mechanic but can do a few things. I could have done all the items listed in 3-4 hours. A shop mechanic can do it much faster. I did this because I think I saved some $$ by doing so.
I hope you enjoyed the videos. I know some were boring or long. I wanted to make it so anyone can view it and do this job. It isn't hard. You can do anything if you have the mind to do so. Keep your shop clean and tools clean.

Grand Prix GTP LIM and Lifter repair progress
I had to replace the lower intake manifold (LIM) gasket and replace the lifters on my 01 GTP as I said in my last video. I'm almost halfway through in this video. It's now Saturday and I should have the rest of the parts here any minute to finish the job up. I'll try and do a bit more video taping before I wrap up to show you a bit more of the process.
2000 Grand Prix GT Series 2 update #2
Just got the heads and lower intake back from the machine shop. No problems found. Rebuilt heads and cleaned lower intake. Dorman upper intake purchased also with the updated EGR tube that does not touch the upper intake. Hopefully it solves the typical failure known to these engines.
GM 3800 Series II Leak
Removed upper intake manifold and was surprised to see...update: Lower intake manifold had previously been replaced with aluminum gasket. This was found with 102,000 miles on engine :(. Upper intake plenum was damaged around EGR.
Bad head gasket symptoms, Head gasget bad? Easy way to check- 200 Chevy 3.8L
This is an Easy way to check for bad head gasket(s) and or warped, possibly cracked heads.
This video shows Co gases (Exhaust gases) entering a vehicles cooling system. this is a simple anti spill funnel placed on your coolant tank and or radiator. simply fill with water and run your vehicle. sometimes it may take a few minutes and other time it will start to bubble right away. I have seen with steel layered head gaskets the cylinder head looses it seal to the engine block over time and starts leaking between the layers.
I have seen some vehicles with as low as 32,000 miles a lot of vehicles around 80-100,000.
Some symptoms can be thermostat codes, misfire codes and 02 sensor codes, bubbles in cooling system, heating problems, oil slime in coolant tank and or radiator, low coolant levels, leaking, split or blown out radiators, leaking water pumps, intake gaskets leaking oil and or antifreeze, catalytic converters that are inefficient or clogged, oxygen sensors that quit working properly and spark plugs that are coolant fouled. If the problem has gone on for long period of time and the gasket(s) is deteriorated enough and the antifreeze is now entering the combustion chamber, then you might have other symptoms of white smoke out the Exhaust and antifreeze mixed in with your oil.
Dealers used to say Maintenance Free, Change your Antifreeze every 5 years or 150,000 miles. Now they say 30,000 miles, which for most of us is about 2 years. Huge difference.
Be mindful of these symptoms and remember to Find and fix the cause not just the symptom.
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
