Yes, until there is a rocker arm or camshaft installed to press valves open.

What is Valves per Cylinder?

It is exactly what it says. The number of valves the engine has per cylinder. If you have 16 valves on an 8 cylinder engine, you have 2 valves per cylinder.


What is cams on a car?

Camshaft opens and closes the valves The CAMSHAFT is connected to the CRANKSHAFT with gears so that the valves (intake and exhaust valves) are opened and closed at the proper time for each cylinder, and fully sychronized for with the movement of all of the other parts of the engine.


How do you determine if both intake and exhaust valves are closed at TDC on cyl?

To determine if both the intake and exhaust valves are closed at Top Dead Center (TDC) for a cylinder, you can perform a visual inspection by removing the valve cover and observing the valve positions. Alternatively, use a compression gauge or a leak-down tester; if both valves are closed, the gauge will show pressure buildup without any significant drop. Additionally, checking the camshaft position relative to the crankshaft at TDC can confirm that both valves are in their closed positions.


What does valves per cylinder do?

In regard to engines TDC stands for?

Top Dead Center, unless otherwise specified, refers to when the piston in cylinder number one reaches the closest it can be to the cylinder head. All the valves should be closed at this point.


How many valves in 4 cylinder vehicle?

16 valves


When engine is in time is cylinder 1 TDC or not?

When the engine is in time, cylinder 1 is at Top Dead Center (TDC) on the compression stroke. This means that both the intake and exhaust valves for cylinder 1 are closed, and the piston is at its highest point in the cylinder, ready for the ignition of the air-fuel mixture. Proper timing ensures that the engine's valves open and close in sync with the piston's movement for optimal performance.
