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.

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.

3100 V6 Ticking Noise
96 Skylark, 3100 SFI V6. It's made quieter ticking sounds before but not
nearly this loud. I've been using part synthetic high mileage oil for
almost a year, just dropped in some Mobile Super Synth and this started up.
Lifter tick? Piston slap? Knock? Something else? Apologies for the
crappy camera work, I was trying to focus on sound and I don't usually
record video. :\
When it started it was erratic, and then it could only be heard at a LOW
idle. Now you hear it until the engine drowns it out at higher revs.

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
