2012-03-06 : Rebuilt GM (Chevrolet) 3100. New main bearings, rod bearings, camshaft bearings, piston rings, head gaskets, valve cover gaskets, EGR gaskets, intake gasket, plenum gasket, Exhaust manifold gaskets, valve stem seals, thermostat, oil pan gasket, oil pump, water pump, oil filter, engine oil, and paint.
I neglected to include piston rings in the audio, but the engine does have the new rings.
3100 Engine Rebuild
Rebuilding a 3100 V6.... Repair cost was $1,200 using Re-man cam and crank.
How To Unsieze An Engine
This is the diesel I got for the Astro van, basically free, with the 700R4
transmission. Which ironically turned out to be a great transmission, the
only one of three that has a good fourth gear, but I rebuilt it anyway.
Who knew a 30 year old automatic could still be sweet inside.
I have unsiezed this diesel engine like this three times now. It
obviously has some internal problems. So its on the list to get a tear
down and rebuild, right after the Ranger is back together. It takes about
an hour or more to get this motor turning over 360 deg. Then it won't
quite fire, but makes little smoke puffs.
The starter in the 6.2 diesel has some serious torque, sucks the battery
voltage down and makes a tremendous amount of heat. It still takes an hour
of cranking an eighth of an inch at a time.
Buick - 3100 SFI Engine Training (1994)
This video from GM's Certified-Plus Training series provides details of the
redesigned 3100 SFI Engine introduced on the 1994 Buick Regal and Skylark.
Topics covered include: 1996 Government Requirements, Engine Introduction,
Management Strategy, Diagnosis Review and Service.
Spinning over a V6 GM engine
The piston sequencing is shown for a 3.4 liter GM V6 engine.
Note, it turns out that I numbered the cylinders wrong, what I call #1 is
actually #2, and what I labelled as #2 is actually #1.
So the Actual firing order as a regular V6 engine, is 1,2,3,4,5,6, I
know, weird, but that is they way they made them. I am more used to V8
engines, so that is why I numbered the cylinders the way I did.
Either way though, it shows that the crankshaft will not work as it is for
the Junkyard Deltic project. Time to cut and weld the crank!!!!!!!!
How to Break In A New or Rebuilt Engine - EricTheCarGuy
Visit me at
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
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.
Please click "like" on this video, as it encourages us to make more! If you
find this video helpful, we'd also appreciate it if you "favorite" it as
well. And, as always, subscribe to our channel for the latest news and
