To find the firing order using a camshaft, you will need to:
1. Remove the valve cover of the engine.
2. Locate the camshaft.
3. Look for the marks on the camshaft that indicate the firing order.
The marks on the camshaft will typically be a series of numbers or letters. The numbers or letters will correspond to the cylinders of the engine. The first number or letter will correspond to the cylinder that fires first, the second number or letter will correspond to the cylinder that fires second, and so on.
For example, if the marks on the camshaft are "1-3-4-2", then the firing order of the engine would be 1-3-4-2. This means that the first cylinder to fire would be cylinder 1, followed by cylinder 3, then cylinder 4, and finally cylinder 2.
By knowing the firing order of an engine, you can properly time the ignition system and ensure that the engine runs smoothly.
Here are some additional tips for finding the firing order using a camshaft:
* If the camshaft does not have any marks that indicate the firing order, you can use a piston stop to find the firing order.
* A piston stop is a tool that is used to hold the piston of an engine in place. By inserting a piston stop into the cylinder of an engine, you can locate the top dead center (TDC) of the piston. The TDC of the piston is the highest point that the piston can reach in the cylinder.
* Once you have found the TDC of the piston, you can use the marks on the flywheel or harmonic balancer of the engine to determine the firing order. The marks on the flywheel or harmonic balancer will indicate the position of the piston in the cylinder.
* By using the TDC of the piston and the marks on the flywheel or harmonic balancer, you can determine the firing order of the engine.
