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!!!!!!!!
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.

Megasquirted 3.1L V6 on stand part 2 of 2
Part 2 of the Megasquirted V6 on the engine stand. The engine
starts...runs, rev's freely, sounds great Screen shots of Megasquirt while
the engine is running and more tidbits of the test stand. The operational
similarities to FIS6 are quite surprising.

Starting the 'other' 2.8 Chevrolet motor 1-23-10
Re-put-together with parts from the 2.8 I shot with my hakim, this engine
had a spun rod bearing which messed up the crank, and rod. I re-assembled
it with the crank from the other engine, and one rod, and fabricated an
adapter plate to mount a 2bbl carb in place of the fuel injection system.
A few issues, but it does start and run. Don't know what I will do with
this engine....in the spring maybe rev it until it blows, or shoot at it.
