Timing an engine refers to the process of setting the correct ignition timing for the engine. In a 22-re engine, ignition timing refers to the moment at which the spark plugs fire in relation to the position of the pistons within the cylinders.

Proper ignition timing is important because it helps ensure that the engine’s fuel is ignited at the optimal time for maximum power and efficiency. If the ignition timing is off, the engine may run poorly, have reduced power, or experience other performance issues.

To time a 22-re engine, the technician will need to use a timing light and a timing mark on the crankshaft pulley. The timing light is a diagnostic tool that allows the technician to see the timing mark on the pulley as the engine is running.

How is a 22-re Engine Timed?

To time a 22re engine, the technician will typically follow these steps:

Prepare the engine: The technician will need to ensure that the distributor is on correctly. One way to check is to have the number one cylinder all the way up, flush with the top of the block while the distributor rotor is pointing at the number one position on the distributor cap.

Locate the timing marks: The technician will locate the timing marks on the crankshaft pulley and camshaft gear. These marks are typically visible on the outside of the engine and can be found using a timing light or other diagnostic tools.

Locate Diagnostics Port: The technician will locate the diagnostics port and insert a small jumper wire from TE1 to E1 to retard the timing. On early 22REs with no diagnostics port, this jumper will be inserted on the yellow plug on the driver side fender well towards the front of the engine bay. This plug will only have two wires coming into it and is usually 

Set the timing: The technician will then connect the timing light’s pick-up lead to the number one spark plug wire and shine the flashing lights on the timing mark on the crankshaft pulley as the engine is running. If the timing mark is not on the place, the distributor may be rotated to move the mark the correct position. On 22RE engines, with the jumper wire in, the timing mark should be stationary on the 5 degree mark on the crankshaft pulley while idling.

Check the timing: The technician will then unshort the terminals on the diagnostic ports use the timing light to verify that the timing is set to the correct specification. The timing mark at idle without the jumper should show anywhere 10-14 degrees BTDC. If the timing is not set correctly, the technician will need to make additional adjustments as necessary.

It is important to note that timing an engine should be done by a trained technician, as incorrect timing can cause serious damage to the engine. If you are experiencing issues with your 22-re engine and are unsure whether the timing needs to be adjusted, it is always best to consult with a mechanic or other qualified professional for guidance.

When to Get Your 22-re Engine Timed?

It is generally recommended to time your 22-re engine whenever you are performing maintenance on the engine or if you are experiencing performance issues. Some common situations in which it may be necessary to time the engine include:

After replacing the spark plugs or spark plug wires: If you have recently replaced the spark plugs or spark plug wires on your 22-re engine, it is a good idea to check and adjust the timing to ensure that it is set correctly.

After replacing the distributor: If you have replaced the distributor on your 22-re engine, it is important to time the engine to ensure that the ignition timing is set correctly.

If you are experiencing performance issues: If you are experiencing issues such as poor fuel economy, reduced power, or engine knocking, it may be necessary to check and adjust the timing to see if it is contributing to the problem.

Overall, it is a good idea to consult with a mechanic or other qualified professional if you are unsure whether the timing of your 22re engine needs to be adjusted. They can diagnose the issue and recommend the appropriate course of action.

To Sum it Up

The timing of the spark plug’s firing in relation to the location of the pistons within the engine’s cylinders is referred to as the ignition timing of an internal combustion engine. The engine needs the right ignition timing to perform smoothly and effectively.

It is generally recommended to time a 22-re engine whenever maintenance is performed on the engine or if any performance issues are experienced.

Ignition timing is crucial for the proper functioning of an engine. Suppose you suspect that the ignition timing of your 22-re engine may not be set correctly. In that case, it is important to have it checked and adjusted by a qualified mechanic.
