Oil spews from dipstick tube...?

My son's Caprice Classic spews oil from the dipstick tube while engine is running. What is/are the cause(s)? Would appreciate any advice. Thanks

well firstmake sure oil level is ok and not overfull.
if oil level is fine it is usually caused by blowby from the engine, worn piston rings which causes pressure to build up in the crankase it may be time for a rebuild or a new car.

I'd also check PCV valve, and filter if applicable. When they're plugged, the engine has to vent somewhere.

Check the PCV system for proper operation also.

Also check and make sure that the dip stick is fully inserted. My jeep has about 40k on the engine rebuild but twice I have failed to fully insert the dip stick resulting in an oily mess

If it is a pre-fuel injection, it could be a bad fuel pump diaphram leaking fuel into the crank case. Does it smell like gas?

Good point, gas mixed in with the oil will overfill the crankcase with diluted oil - not good for the motor
