TITLE: Oil Pumps - Replacement Versus Resealing
APPLIES TO: All models
SERVICE TIP:
When diagnosing a leaking oil pump, don't automatically replace it with a new pump when a simple reseal will do. It seems that a large number of pumps
are being replaced when a reseal would have solved the problem.
The only time a pump should be replaced is if the housing is porous, cracked, or damaged in some other manner.
