The purpose of this Bulletin is to provide procedures for the diagnosis and repair of oil seepage
which may be coming from the areas listed below:
There are six areas that should be closely inspected if an oil leak is reported by the customer:
1. The 6mm tapped hole casting boss area in the left-hand camshaft cap
2. The sealing surfaces between the camshaft carrier and cylinder head
3. The sealing surface between the cylinder block and the upper oil pan
4. The sealing surfaces of the front timing chain cover
5. The sealing surfaces between either the left or right-hand camshaft cap and/or camshaft carrier
6. The sealing surfaces between the cylinder head block-off plate (on M/T models) or the vacuum
pump assembly (on A/T models)
