INTRODUCTION
If you encounter a customer complaint concerning white smoke from the exhaust pipe and/
or high oil consumption, it may be the result of the # 1 and/or # 4 intake valve guide insertion
hole improperly machined, permitting oil to enter the combustion chamber. To remedy this
condition, the cylinder head(s) will need to be replaced. Please read this bulletin in its entirety
before proceeding.
Insertion hole is not
perfectly round.
NOTE: There is a possibility that some of the cylinder heads were installed on engines that
were installed in vehicles within the following ranges.
