Fuel in Engine Oil
DEFINITION: If fuel is suspected of leaking into the crankcase,
the following procedure should be performed to verify the
condition.
| • |
Remove the oil level indicator
and allow oil to drop onto a clean white paper towel. |
| • |
If the oil is diluted with
fuel, it will become apparent as the towel wicks the fuel away from
the drop of oil on the towel. The fuel will expand out in a ring
around the oil droplet. |
| • |
If fuel dilution is apparent,
inspect the vehicle for aftermarket performance accessories that
may cause damage to the injection pump. After repairs are
completed, perform the test again to verify the condition is
corrected. |
| • |
If no fuel dilution is
present, verify the oil level and correct as needed. |
