My oil dip stick keeps popping out! Is there a fix?


The dip stick is often usually forced out by excessive crankcase pressure.  In many cases, however, this is not due to an increase in crankcase pressure - rather, it is due to a decrease in the holding power of the dip stick.  Lots of these cars are over 5 years old, with many approaching the 10 year mark, and most rubber parts have lots their original resiliant nature.  The rubber plug on the dip stick may have shrunk and hardened over time, causing the stick to come out more easily than before.

If replacing the dip stick rubber doesn't help, the positive crankcase ventilation (PCV) valve is often at fault.  This is an inexpensive little part that is supposed to vent excess pressure, but it can wear out or clog.  A quick replacement may be in order.

Another possibility is replacing the breather hose with a small K&N valve cover filter, which will hopefully help to vent excess pressure.  Bad turbo oil seals and worn piston rings are the next likely suspects.

Tip: Attach a small clamp near neck of oil tube. Then find a spring that will hold on to the diptick and attach other end of spring to clamp.
