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 ( 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
consists of water pump, hoses, radiator, thermostat, cooling fan and
coolant recovery tank. Also the oil system serves as a cooling system as
well as a lubricating system. It consist of oil pump, pan, filter and
1. Clutch: Purpose is to connect the engine and transmission together. It
consists of clutch drive disc, driven disc, release bearing, clutch fork,
cable, slave cylinder, master cylinder. There are three types of clutch
systems: mechanical, cable and hydraulic.
2. Transmission: Purpose is to match engine speed to road speed. Two types
used are manual or automatic. These consist of gears, linkages, cables and
converters for automatics. A manual is connected to the clutch by a
flywheel and automatic by a flexplate.
3. Driveshaft: Purpose is to connect the transmission to the rear axle. It
consists of a slip yoke, shaft and universal joints.
4. Rear axle differential: Purpose is to change the angle of motion from
engine to the wheels. It also divides torque between the wheels. It
consists of a ring and pinion gear, carrier, bearings, crush sleeve and
5. Wheels/Tires: Purpose is to provide traction to the road as well as
carry the weight of the vehicle.
Vehicle Control Systems:
1. Brakes: Purpose is to slow and stop the vehicle. It consists of master
cylinder, brake Booster (vacuum or
hydraulic), calipers, drums, pads and rotors.
2. Steering: Purpose is to direct vehicle in the required direction.
Consists of steering gear (rack & pinion), steering wheel, column,
inner/outer tie rods, pump, reservoir, hoses and pipes.
3. Suspension: Purpose is to provide stability and handling while also
providing comfort to the ride. Consists of shocks, struts, sway bars, end
links, springs, trailing arms and bushings.
1: Heating Ventilation Air Conditioning (HVAC): Heats and cools interior
air to passenger comfort. Also circulates outside and inside air.
• Air Conditioning: Consist of condenser, compressor, accumulator
(receiver/dryer) orifice, expansion valve, hoses, evaporator, controls,
actuators and modules.
• Heating: Consists of heater core, valves, hoses and switches.
1. Power Generation: Creates electrical power to run all the electrical
systems. Consists of the alternator.
2. Power storage: Stores unused power to start the car and supply voltage
to the alternator to create more electricity.
• Both systems consist of wiring, harnesses, fuse, relays and modules
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!
Mercedes Straight 6 Engine Vs. V6 Engine - A Quick Comparison
Using a W124 wagon and a W210 wagon, Kent shows you some of the basic
differences between the older M103 straight six cylinder and the newer M112
V6 introduced in the late 1990's. Opinions abound and of course Kent has
his own too. See if you can figure out which he likes best....
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!
How To Perform a Parasitic Draw Test - EricTheCarGuy
This video has been a long timing coming and is one of the most requested
things I get is about batteries going dead overnight so I'm very happy to
finally bring you this video about the process of finding a parasitic draw
which is a small drain on a battery above 50ma when the vehicle is shut
off. Once you find the right fuse(s) the next step is to trace the
components involved in that circuit till you find the source of the draw,
you first start with a wiring diagram to give you an idea of where to start
looking and then start unplugging things in that circuit to isolate the
cause, it's quite scientific really a simple process of elimination. Here
is a link to BBB's site that you can use to look up wiring diagrams for
Good luck and if you have anymore questions check the database on my
website and if you don't find what you're looking for there then post your
question to my forum, here's a link.

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.
Setting the initial timing on a chevy small block PT2
Setting the initial timing on a Chevy small block. I have set the timing on
over a hundred small blocks, and rebuilt many a classic chevy, for a time
it is what I did for a living. This is a THREE part guide on how to set the
initial timing. I am very repetitive, and go slowly over this process. Find
top Dead Center of your #1 cylinder, line up your rotor with a cap tower,
that tower is number one. Run spark plug wire from #1 tower to #1 cylinder,
then go around the cap from there. This is for Chevy small blocks, the
order is 1-8-4-3-6-5-7-2. Hopefully this helps someone. Thanks for viewing.
For those of who you watched all three and want to tell me I am wrong, this
won't set TDC, make a video of your own, tell me how you set TDC, if you
use a vacuum gauge it's the same thing as feeling the piston stroke your
just watching gauge tell you where you at versus a dowel or wire. And I am
going to start deleting, wait I have deleted some already, comments that
state the advance for certain engines. Cam, Dizzy, and vacuum advance
cannisters, will change what you should set the advance at! So don't tell
everyoneto set thier 350 at X, when with a bigger cam X won't be right. And
if I get one more moron telling me the firing order is wrong I will send
them a bus ticket to come here so I can personally slap them in the head.
