Type 1 Engines and 9RM Engines
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.

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.
