The 1996 has 12 valves, they did not start putting the 24 valves in the pickup until 1998.5. Hope this helps.
Only gas engines use blow off valves.
Yes. The camshaft operates valves that permit air entry to the cylinder, and exhaust exit from the cylinder. Many modern engines have two camshafts, one for the inlet and one for the exhaust.
On a standard V12 it has 24 valves however some newer engines have 3 or 4 valves per cylinder making the number 36 or 48.
In many cars YES, but not all cars.The engines will be "Interference Engines" or "Noninterference engines"When the belt breaks in interference engines the valves strike the pistons and bend.
Some two stroke engines have 4 valves, Detroit Diesel 71 series and 53 series engines for example. Most small 2 stroke engines have no "Valves" at all in the sense of the "POP" valve used in four stroke engines. Some people feel these engine has one valve because the piston acts as the valve covering the ports cut into the cylinder walls.
Gasoline engines can be designed so that even if the timing belt breaks, the valves will not contact the pistons, regardless of what position the camshaft stops in (a so-called non-interference engine). Not all gasoline engines are non-interference ... but they can be. This is impossible with a diesel engine because of the high compression ratio, and the small space between the piston and head in order to achieve that compression ratio. All 4-stroke diesel engines are therefore interference engines.
This question is not really specific enough.
Pneumatic valves are used to close valves in high-speed internal combustion engines, pneumatic valves are mostly to help racing engines to get to high speeds.
The camshaft.
there are lots of differences. one no spark plugs. diesel fires by compression and heat gas or petrol requires a spark. the fuel delivery is diffrent to diesel is usally injected under a higher psi to areosol the fuel better. but diesel is more like fuel injection because the valves are diffrent
Generally, the more valves an engine has the more efficient it is.
