Illustration 1 g00296342
Cylinder and valve location for Type 1 engines and 9RM engines
(A) Exhaust valves
(B) Inlet valves Note: Type 1 engines can be identified in two ways. The first method refers to Illustration 1. When the valve cover is removed, look at the cylinder head valves. Type 1 engines have two exhaust valves in a row and two inlet valves that are in a row.The second method does not require the removal of the valve cover. Refer to the inlet manifold and the exhaust manifold. Type 1 engines have two exhaust ports in a row and two inlet ports that are in a row.Type ... Four cylinder and four strokeCombustion system ...

Cylinder and valve location for Type 2 engines and 7BJ engines
(A) Exhaust valves
(B) Inlet valves Note: Type 2 engines can be identified in two ways. The first method refers to Illustration 2. When the valve cover is removed, look at the cylinder head valves. Type 2 engines alternate the exhaust valves and the inlet valves.Note: Some of the Type 2 7BJ engines may look like the Type 1 engines. When the valve cover is removed, these engines may have two exhaust valves in a row and two inlet valves in a row. This is only a small percentage of the Type 2 7BJ engines.The second method does not require the removal of the valve cover. Refer to the inlet manifold and the exhaust manifold. Type 2 engines alternate the exhaust ports and the inlet ports.Type ... Four cylinder and four strokeCombustion system ...
