How do you find the top dead center of an engine?
Step 5: Verify that the engine is in top dead center position. Once the top dead center timing mark is lined up with the marker on the engine, the motor should now be at top dead center. To verify, shine the flashlight down into the spark plug hole. You should be able to see the top of the piston clearly near the top of the cylinder.

What does it mean when engine is timed to zero degrees advance?
On an engine timed to zero degrees advance, also known as Top Dead Center, that mark will appear to flash with the light pointed at it. If you loosen the distributor and turn it slightly, you’ll see that mark move to the left or right. Turn the distributor too much and the mark will leave entirely. You can also shut off the engine in this way.
What causes the engine to go to TDC?
As the engine is rotated, the piston will force the dowel upward. When the end of the dowel is at its highest point, the engine is at TDC for the #1 cylinder.
What’s the best way to find the top dead center?
Doing so can be easy with ordinary hand tools, but using a piston stopper tool specifically designed to help find top dead center will yield the most accurate results. Disconnect the battery. Before beginning the project, use a hand or socket wrench to loosen the nut holding the black “ground” cable on the negative terminal of the battery.
How do you find the center of an engine?
Find the center point between the two marks. With both marks clearly visible, find the center point by measuring the distance between them and dividing by two. That should allow you to measure from on of the two lines and identify the exact center point between the two. That center point is top dead center.
