Top dead center (TDC) refers to the position of a piston at the highest point in its cylinder. It can occur at the end of both the compression stroke and the exhaust stroke, depending on the engine cycle. During the compression stroke, the piston moves upward toward TDC, compressing the air-fuel mixture before ignition. Therefore, TDC is not exclusively the compression stroke; it is a position that can be reached at different points in the engine cycle.

It is when the number one cylinder has reached top dead center on the compression stroke.
the piston in cylinder #1 at the top on the compression stroke
That would be the top of the compression stroke on the number one cylinder.
Presumably we are talking 4 stroke? If so, none or the exhaust - it will be at the top of the compression or the exhaust stroke
yeah men
In the field of automotive repair, we always refer to top dead center as. The #1 cylinder being at the TOP MOST POSITION during its compression stroke. The 22RE is no exception.
#1 piston must be at TDC / Top Dead Center on the compression stroke.
It will be if #1 piston is at TDC on the compression stroke. When they are lined up.
At TDC, on the compression stroke, the rotor will will be pointing at the # 1 spark plug electrode on the distributor cap.
Yes
yes it does need to be facing towards it
