The most common setting for the 351W is 6° before top dead center . Therefore, if you were to hook a timing light to your engine, you’d want the 6 to be aligned with the timing pointer for the first style, and you’d want the third hashmark before the TC aligned with the marker for the second style.
How do you set the timing on a 351W?
to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it.. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks.. tighten down the distributor..
What are the symptoms of timing being off?
- You Hear A Ticking Noise Coming From The Engine. ...
- Your Car’s Engine Won’t Turn Over. ...
- You Notice An Oil Leak Near The Motor. ...
- You Experience Exhaust Issues. ...
- Your Revs Start Acting Up.
How do you set timing without a timing gun?
to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it.. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks.. tighten down the distributor..
How do you tell if your timing is 180 out?
You can determine if it is 180 out by removing #1 plug and placing your finger/thumb over the hole . (Temporarily remove the wire from the coil first) Have someone “tap” the starter and you will feel pressure trying to to blow your finger away. This is the compression stroke. Note the direction of engine rotation.
How do you check timing?
to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it .. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks..
How do you set the timing timing on an ignition light?
The ideal ignition timing for power occurs just before the point where detonation or pinging takes place. Correctly timed ignition will cause peak cylinder pressures to occur around 12 to 15 degrees after TDC .
What causes ignition timing to be off?
The ignition timing error is typically caused by damage internally like the pistons or valves inside the engine. A loose or weak engine timing belt that jumps time can cause the ignition timing to be off.
How much does it cost to set timing?
The average cost to replace a timing belt will be anywhere from $300 to $500 in total (more for larger cars, trucks, and SUVs). The timing belt itself will usually only cost less than $50 but the majority of a timing belt job is spent on labor. The cost of the labor will be anywhere from $250 to $450 or more.
What would happen if the timing was out of phase?
If the timing is off, damage can occur . In some engines, called “interference engines,” the consequences can be especially bad. ... You could end up having to have your engine rebuilt, or even replaced. If your cam timing
Are valves open or closed at TDC?
It’s up to you. Both valves should be closed if it’s TDC at the end of the compression stroke . If it’s TDC at the end of the exhaust stroke, you should be in the valve overlap zone, with the intake valve partially open and on its way to opening fully, and the exhaust valve partially open on its way to closing.
What is initial timing?
Initial timing refers to where the timing is set at an idle . This is also where you position the distributor when setting the timing. Generally, this will be 6° or 12° or something lower, depending on the application.
Can you check timing while cranking?
Unlike the relative compression test, this test can be done during engine cranking or while the engine is running. In addition, very accurate ignition timing measurements can be made. ... Figure 6 – Ignition timing while running should be advanced.
What happens if timing is too advanced?
If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle . This can cause the amount of heat generated by the combustion process to increase and lead to overheating of the engine.
