What is difference between overhead valve engine and overhead cam engine?

Mainly, the difference is that in an overhead cam engine, the camshaft is mounted on the head of the engine, and the valves are still overhead, in an overhead valve engine (sometimes called a "pushrod motor"), the camshaft is in the crankcase.

What is the difference between a 94 Chevy cavalierZ24 and a 96 Chevy lumina Z34 motors?
The Z24 engine is an overhead valve engine and the Z34 is an overhead cam engine. The Z34's engine is pretty tight in it's engine bay so if you were thinking of doing a "swap", Z34 engine will not fit in the Z24.

Single Overhead Valve Engine
Where can pushrods be found in a engine?
Under the valve cover, of an overhead valve engine. They push the rockers on the opposite side of the valve stems. Overhead Cam engines do not have push rods.
What is the difference between overhead cam and overhead valve?
Overhead valves open vertically from the head into the combustion chamber. Overhead valve engines use a system of lifters, push rods, and rocker arms to operate the valves. The cam on an overhead valve system is adjacent to the crankshaft, and the lifters, push rods and rockers work together to operate the valves. Overhead cam engines position the camshaft directly above the valves. In that position, there is much less weight of the valve operation mechanism, resulting in a potentially higher engine operating speed.
What is the difference between 2 valve and 4 valve engine?
In short, More Power.
What is difference between overhead valve engine and side valve engine on lawn mowers?
An overhead valve (valve in head) engine has the valves in the head (not in the block) and they are in line with the motion of the piston, but are above it. Valves are usually operated by push rods or by overhead cam (driven by timing belt/chain from the crankshaft). The engine can be in any orientation : ie the cylinder motion could be horizontal or vertical. Overhead valve engines are high performance engines used in motor bikes and cars A side valve engine has the valves in the block (not in the head). The valves are parallel to the piston motion and are placed just beside the cylinder. Valves are lifted by a camshaft, gear driven off the crankshaft. This arrangement is also known a 'L-head' engine. Advantages are that the head is simpler. The flow of fuel and exhaust gas is less efficient than overhead valve engine. due to having to make a 90 degree turn. Compression ratios are usually lower with side valve engines, so they will run happily on lower octane fuel. Side valve engines are mostly used on lawnmowers etc.
When was the first overhead valve 6-cylinder engine made?
The original overhead valve or OHV piston engine was developed by the Scottish-American David Dunbar Buick around 1902.
Does a 1988 Cadillac DeVille have a northstar engine?
No it does not. The only engine in the 1988 Cadillac De Ville was the 4.5 Digital fuel injected engine. The 4.5 engine is a 2 valve per cylinder overhead valve (not overhead cam) engine. It was a good engine but not in the power category as the Northstar.
How do you run overhead on a 3126 caterpillar?
You can run the overhead, on your 3126 Caterpillar diesel engine, by removing the valve covers. The overhead can be adjusted with the adjusting screws.

Type your answer here... They are in the cylinder head.
What is An overhead valve engine?
A 4-cycle engine that has the intake and exhaust valves located in the cylinder head.
