multiply the number of cylinders you have by 2. normally only 4 cylinder and some 6 cylinder engines have 4 valves per cylinder. if in doubt remove the valve cover and count the number of rockers or cam lobes if it is an overhead cam engine. easiest way to find out for sure is to look your specific engine up on the web.
There are so many variables in answering this question. A standard v8 engine will have 16 lobes, 1 for each valve while an overhead cam engine will run 2 cams with 8 on each side.
On an overhead cam engine, the lobes on the cam push the rocker arms which push the valves open.
no, the cam shaft is on the engine cylinder head..
In the back of the cam shaft there is a slot that must be "level" with the head. Slide a flat stock of steel in the slot. Both valves must be closed on #1 cylinder. This can be determined when both the cam lobes are pointing up.
Start with flywheel on the T mark with the piston up . The cam lobes should both be down . With the lobes down the pointer on the cam gear should be straight up , pointing toward the mark on the engine housing . Make sure your camchain tensioner is removed . Put cam chain on cam gear and check that all marks are aligned . This is also where you need to adjust your valves .
These cars are the Twin-Cam 6 cylinder engines = 24 valves.
It is in the cylinder head.
If the peaks of the cam lobes are all worn the camshaft needs to be replaced. It will affect the valve timing and the air intake into the engine which in turn affects the performance.

In a 1999 Ford Contour : The 2.0 litre four cylinder engine has ( 2 cam shafts on top of the cylinder head ) The 2.5 litre V6 engine has ( 2 camshafts on top of each cylinder head so there are 4 camshafts )
Yes , the 2.5 litre four cylinder engine in a 1999 Ford Ranger is a Single Over Head Cam engine
