oil everywhere

ive narrow down the appx location where im getting oil leaking from and going all over the engine bay. I'm pretty sure its coming from the top of the dipstick. it seats good but everytime i check its out a lil bit. Sooo, where can i get as close to oe as possible? or is aftermarket better?

its not the dipstick its your lack of a properly working PCV system, i would look at pcv valve first and go from there

You still have pressure building up inside the engine and it is finding its way out the dip stick. The PCV system is supposed to bleed the pressure off, so it cannot be functioning properly if oil is being forced out the dip stick tube.

I agree again, unless of course, you are constantly up on two wheels, drivers side down. THAT would cause oil to gush out the top of the dipstick, I would think.

My wife would kill me if I drove like that...

Are you married?

a proper pcv system consists of a good pcv valve,and a oil cap that breathes, the goal is for the smoke and oil mist gets caught in with the air being sucked from pcv valve through the breather and goes into the pcv vacuum port on the manifold

Worst case scenario is there is too much pressure inside for even the pcv to handle ie:blowby.

Hole in piston? Broken rings?

How does the engine run? When running, take off the oil fill cap and tell us what happens.

When the vacuum line to the PCV has dry rotted off, my truck would expel the pressure out through the dipstick. It never came off, but it certainly unseated itself from that 'clicked in' position. Never any oil, however.
