I'm sure there is more than one way to do this but this is the way that I
was taught and it seems to work as intended. The idea is to make sure the
engine is fully lubricated before you start it up for the first time as we
know all too well what happens to an engine without oil, in fact I forgot
to show me filling up the oil filter with oil before I installed it sorry.

Fix It Right! - Intake Manifold Gasket Replacement (S1E4)
Demonstrated on a 2004 Buick Century 3.1L V6 FWD.
In this video, we demonstrate how to perform an intake manifold gasket
replacement on a front-wheel-drive 3.1L V6 engine, in this case in a 2004
Buick Century. This is a common point of failure on General Motors' 3.1L,
3.4L, and 3.8L V6 engines, which are used in a large number of passenger
cars across most of GM's model lines.

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.

Part 2 GM 3400 How to Replace a Bad Blown Head Gasket Reassembly Overheats No Vent Heat 3.4 Liter
Part 2 Reassembly on a head gasket change for a GM 3400. Basically the
same as a 3.1 Engine. Here are a few torque ratings that I used while I
was putting it back together.
Head bolts 65 foot pounds, torque to 40 in criss cross pattern, then 50,
55, 60 then finally 65
Rocker arm bolts 40 foot pounds then up to 50.
The rest were just hand tightened down good. Got questions? Stuck on one
certain area? Give me a shout out! I'll help answer your questions best I
can. : )
Replaced the head gaskets on this 3400 because they were bad. Engine would
overheat. If you watch at the end of the first video, the dismantling,
you'll see the bad areas of the head gasket

Replacing Chevrolet Lower Intake Manifold Gasket
New intake gaskets on a 1997 Malibu LS 3100 motor. This is a very common
issue with these cars. In this video I take you though the whole process
not in a professional shop but in a drive way so you can get a realistic
look at whether or not this fix is for you.
Make sure you get the steel replacement gaskets as that will solve any
future leaking issues.

GM 3400 / 3100 3.1 3.4 Engine Misfire Cause & Causes Miss Missing P0303
Here is a video for fellow GM 3400 & 3100 liter engine owners. Have a
misfire? This video explains the causes for what could be causing the
problem. Mine showed up as a P0303 cylinder 3 misfire. Couldn't figure it
out, but finally did. The spark plug and wire were replaced along with a
new coil. Could hear the injector firing with a stethoscope but still had
the miss. Found out after tearing into the intake that the lower intake
If your car is missing out, first try the following. Check for spark and
check the spark plug, wire and coil. A test you can do if it randomly
misses is in the dark, spray a mist of water around the plug wires. If you
see blue arcing, you've found the problem. But be careful not to zap
yourself, IT HURTS!
If the spark is good the listen at the injector. Is it firing and
clicking? If not, you've found the problem.
If both those seem good, then check for compression. Do this with a
compression tester available at any Autozone with the loan a tool program
If all 3 of those check out then it's a possible vacuum leak. May be time
to do an intake manifold gasket repair as they are known to go out. But,
if you do have to do an intake manifold gasket fix, go ahead and replace
the head gaskets too. You'll be glad you did. Not fun taking it all back
apart again. Check out my youtube channel for these videos both on doing
the lower intake manifold gasket and the head gasket.
