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!!!!!!!!
Un-seizing a V6 engine #4
The V6 engine I have is seized up, so I show how I get it to spin over
Note some of my techniques are not recommended for a useful engine. One of
the most important factors is time, the longer you let diesel or
penetrating oil sit in the cylinders, the better, so long as you keep any
water out at the same time!
GM ( Chevrolet or GMC ) 4.3 L V6 Engine Tear Down
This video goes through the teardown process of a GM 4.3L V6. It has been
removed from the vehicle and we take it apart, except for crank and piston
The automobile consist of:
• Fuel System: Purpose is to deliver fuel to the engine. It consists of
the fuel tank, pump, gauge/sensor, filter, pressure regulator and
• Air Intake System: Purpose is to clean and direct outside air into the
engine. It consist of air filter, ducts, air plenum and intake manifold.
• Exhaust System: Purpose is to
direct Exhaust gasses out of
combustion out of engine. It consists of the Exhaust manifold, converters, pipes and
• Cooling System: Purpose is to remove excess heat from the engine. It

Awesome V12 Monster diesel engine Awake and Alive startup
The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.

Design of Junkyard Baby Deltic #3
Design features of the proposed junkyard Baby Deltic are shown here.
Third vid in the series, with at least 3 more to follow.
I describe some of my ideas on how to build a 9 cylinder Deltic type 2
stroke opposed piston engine from three V6 car engines. Note, there are no
gaurentees that a person could actually make this work, as there are many
challenges to overcome!
Strauss Drives a 6 Cylinder
An assignment in the 3rd year of my degree at Murdoch University (MUL338 in
2004). Shows the workings of a 2.5 Litre 4 Stroke inline 6 cylinder
internal combustion engine. Set to Stauss' Blue Danube. In hindsight that
was SUCH a corny choice of background music. Modelled, animated and
rendered using Lightwave 3D. Post production editing in Adobe Premier Pro.
New NRE E85 2100 HP Monster Blows Intercooler! Nelson Racing Engines Episode 215. NRE TV.
This may be the best NRE Dyno ever. This video has more
than its share of action and drama. This is the first monster E85 engine
Tom has produced. Lot's of flames and even explosions! I think this video
has the hottest headers NRE has ever cooked. We hope you like it. Thanks

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.
