I've been reading and there all tdc. But some people are saying to wait for the third mark. If you do find out what the mark is. Please tell me
It is the "Advertised duration", used by the factory. It is the Valve timing from when the valve is .006inches off the valve seat to .006" off the valve seat.
According to Wikipedia, a variable valve timing is a "process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions".
one mark is used for inductive timing with a special timing tool and the other is for a conventional timing light
Variable valve timing is used on numerous cars and trucks. The Chrysler 3.6L which is used in most new Chrysler vehicles for example.Variable valve timing is used on numerous cars and trucks. The Chrysler 3.6L which is used in most new Chrysler vehicles for example.
The two timing marks on a 4-cylinder engine's crankshaft or camshaft indicate different reference points for timing adjustments. One mark typically aligns for ignition timing, while the other may be used for valve timing or synchronization with other components. This dual marking helps ensure accurate timing during engine assembly and maintenance, allowing for precise adjustments to optimize engine performance.
Both valves of the number one piston must be closed. This happens when the camshaft gear timing mark is lined up with the mark on the camshaft seal cover(mark is right on top-a notch in the top center of the plate of metal sticking up). The problem is that there are two marks on the gear and both have the "E" stamped nearby as required. Through trial and error I was able to determine the one that created pressure from the piston(because the wrong mark, when lined up, left one or more valves open so I felt no pressure.) Yet I still had problems getting the timing correct.

It is a dot, dash, line, or arrow that is used to "time an engine".
The timing mark for the 4JG2 engine is typically located on the crankshaft pulley or the timing belt cover. It is used to align the engine's timing components properly during maintenance or when setting the timing. You can usually find a corresponding mark on the timing cover or engine block to indicate the correct alignment. Always refer to the vehicle's service manual for precise locations and alignment instructions.
On my 2000 Metro with a 1.3L the mark and slot marked with the "E" are used.
To connect a heater control valve on a mark 5 fiesta all the terminals must be correctly connected. The color coding is used to ensure that the terminals are correctly connected.
You must make sure you have the distributer mark aligned with mark on the intake manifold. The PCM makes all the timing adjustments. Info: The distributor is only used for the cam position, and spark distrubition.
