SUBJECT: PCV System
INTRODUCTION
The purpose of the bulletin is to inform you of a modification made to the PCV system.
As the engine heats & cools, condensation (water) can accumulate in the PCV system. In extreme cold temperatures and under very rare conditions, this water can turn into ice. This may restrict or block air flow through the PCV system. When the engine's PCV system cannot "breathe" properly, excessive crankcase pressure can build resulting in oil seal displacement/leak, smoke from the exhaust or excessive engine oil usage. Once thawed, the blockage is gone and the PCV system returns to operating normally. If you encounter a vehicle that you suspect may have experienced this condition, a PCV Repair Kit should be installed.
COUNTERMEASURE IN PRODUCTION
