Valve degrees vary accouding to the manufacturer of the engine. Specs are givien for each engine in a manual that displays valve timeing and valve degree of angle. This is importan because the valve angle must match the head angle already cut into the head by the manufacturer. I have seen everything from 12 degrees to 45 degrees and sometimes multiple degrees. It is according as to what you want the valve to do. More top end speed, less top end speed double fire, tripple fire, advance and retard mechanisms and other factors.
PCV valve on top of the valve cover towards the end of the cover. Will have a 90 degree black rubber boot on it.
Three. Inlet valve, fuel injection valve, exhaust valve.
Could be--valve not closing completely
Intake Valve open 64 Degree BTDC and closes at 34 Degrees BTDC. Exhaust valve opens at 36 or 37 Degree's ATDC and closes at 79 Degrees ATDC
Which valve? Engines have many! You need to be very specific about this!
between firewall and engine, between a rubber hose that leads to the valve cover and a short 90 degree hose to a vacuum nipple.
The valve spring is the spring that closes the valve in the engine head after the cam lobe or rocker opens it . If the valve didn't close, many things would happen , the main one being the motor would not fire .
Valve created the Half-life and Half-life 2 game engine. Valve is a corporation not a game engine.
