| 122-V3U7E-06 | 2017-08-01. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE (PCV); ENGINE AND ENGINE COOLING. Concerns: Plug on crankcase for cylinders 1-3. Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. There is the possibility that a plug that was pressed into and sealed to the crankcase is not seated securely enough in the opening on the affected vehicles. As a result, this can cause the plug to become loose and as a result, oil can suddenly leak out of the crankcase, resulting in immediate engine damage. |
