turned my truck off an poped the hood an oil was gushing out the dipstick. its done it twice before. do i need a new dipstick??

 

Check the PCV valve.

 

would that make difference?

 

A blocked PCV valve and/or the attached hose can cause excessive crankcase pressure and blow oil out the dip stick tube.
Make sure the oil level is not too high.
If not that then another possibility is bad ring(s).
Any smoke or oil fouled spark plugs?

 

not that i know of. i'll have to check one day
