What is camshaft adjustment?
Camshaft adjustment varies the opening times of the valves to suit all operating conditions. This ensures ideal charge cycles within a wide range of engine speeds and loads. Fuel consumption and pollutant emissions are reduced, while torque and smoothness are increased.
How many crankshaft degrees of adjustment do exhaust cam phasers have?
The phaser body is physically bolted to the camshaft sprocket and the rotor is connected to the camshaft using a dowel pin. The two pieces can move about 20° (40 crankshaft degrees) independently of each other. Ports inside the phaser direct oil in or out of eight chambers.
Where does the crankshaft go when setting to TDC?
So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
When to set engine to top dead center ( TDC )?
Procedure NOTE When setting the engine to TDC on the compression stroke for cylinder #1, you must realize that the crankshaft rotates twice for every single rotation of the camshaft. So, if you simply set the crankshaft to TDC without looking at the position of the camshaft, you may actually be at TDC on the exhaust stroke for cylinder #1.
How can I tell if my engine is at TDC?
So, after you get the crankshaft (by flywheel indication or by checking actual piston location), check the camshaft sprocket to make sure the camshaft alignment mark is at the TDC position as well. This procedure can be performed by one person. However, it is much easier to perform with two people.

How to test crankshaft and camshaft position sensors?
Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It’s very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.

What makes a Level 1 replacement camshaft good?
Level 1 indicates a good stock replacement camshaft. These profiles are designed to enhance throttle response and low end torque in vans, trucks, passenger cars and mild marine applications while delivering fuel efficient motoring. High vacuum, smooth idle and maximum efficiency are characteristics of these cams.
