How to Time a Four Stroke
Its not difficult to time a four-stroke. Youll need to make a habit out of checking the ignition timing mechanism. This is a vital part of figuring out the present state of your engine. To begin a four-stroke engine timing check, all thats required is access to a single spark plug.
Instructions

Locate the magneto. The magneto is the section where each plug wire converges. Select the closest cylinder to you. Assign that particular cylinder as the main cylinder. Locate the center of the compression stroke. Take off the spark plug and remove it from the cylinder.
2Put a finger on the spark plug hole. Use the wrench against the crank bolt. Now turn the wrench clockwise. Take the pencil and place it into the hole. Push it forward until the tip of it reaches the top of the piston. Move the crank forward and backwards to locate the highest point of the piston. The cylinder will be dead center. Switch out the wire and spark plug.
3Locate the erence mark on the crankshaft pulley. Place marking tape on the crankshaft pulley. Clamp down on the spark plug wires inductive pickup. Make certain that it goes to the main cylinder. Clip down on the positive battery terminals red wire. The negative battery terminal should be place on the black wire.
4Turn on the engine. The timing light should now be pointed at the crank pulley. Do this while the engine idles. Shut off the engine. Put another mark onto the pulley. This mark should correspond with the second mark. Start the engine again.
5Confirm that the second pulley marking tape section aligns with the marking tape lines on the engines block. Shut the engine off. Detach the vehicles timing light. The degree wheel should now be placed on the crank pulley.

How to Replace a Ford Power Stroke Turbocharger
The Power Stroke is Fords top tier diesel truck engine that can generate as much as 800 foot-pounds of torque, thanks to a turbocharger. This device is a turbine that is powered by the exhaust gases to push more air into the combustion chambers. By increasing the amount of air in the engine, the combustion process is made more powerful and efficient. However a turbocharger may eventually need to be replaced, since it is subjected to high pressure that can damage parts like turbine blades.

Turn of the engine and engage the parking brake. Open the hood and place a step stool next to the engine compartment to make it easier to reach the components. Put drop cloths over the fenders to protect the finish. Disconnect the negative cable from the battery to prevent a short circuit.
2Remove the clips holding the cover of the air filter housing and remove it. Unbolt the bottom of the air filter housing with a wrench and pull the plastic shield out. Unscrew the air intake line O-ring clamp from the front of the turbocharger. Pull the air line off and place it to the side. Unplug the ECU wire from the side of the turbocharger and place it out of the way.
3Unbolt the turbocharger from the down pipe that leads to the front of the V-8. Then unbolt the turbocharger from the exhaust manifold on the top of the diesel engine. Pull the turbo out caully because it is heavier than it looks. Place the new turbocharger on the exhaust manifold and thread the bolts in by hand. Then thread the bolts in on the down pipe by hand. Once all the bolts are in then wrench the bolts down flush. Plug the ECU wire in on the side of the turbocharger.
4Place the intake pipe on the front of the new turbocharger and screw the O-ring clamp down tight. Replace the air intake housing and reattach its bolts. Replace the air filter and snap on the top of the air housing. Reconnect the battery cable, remove the drop cloths and close the hood.
