uh oh. please help!

got a 1994. if u pull the dipstick out of the tube while the truck is idling the blow by is so bad it shoots oil out of the tube onto the motor. any ideas?

[gary502]

i got the same problem, just leave the oil fill cap off or add a valve cover breather....

How many miles does the truck have on it? What all is done to it? Does it have a pulse to the blowby? Could be bad rings, hole in a piston, or vacuum line leak somewhere causing excess crancase pressure.

[coal_roller_94]

but is something wrong. like blown rings?

Obviously there is an issue somewhere, the answers to the above questions will tell you how bad it is.

If you're going to hang around awhile, why don't you put all that in your sig? I'd plug the vacuum pump and see if it quits.

[coal_roller_94]

do u mean rebuild the vacumn pump?

see if your blow-by tube hangin off the left hand side of the engine behind the pump is clogged
