You could try putting a new oring on the dipstick yet maybe there's a rip in the old rubber piece in there.

i put a new gasket on dip stick and it still leaks. but when i take the fill cap off steam comes out and no oil blows out of the dipstick when thats off. i put my hand over the oil fill and i cant feel any kind of pressure pushing on my hand or blowing it off. when the cap is off it sounds like metal hitting metal in there i don't know what it is. so i put a universal filter from auto zone on it and it dosn't seem to leak. so can i put performance mods on this motor or will i b wasting my time?

genosgarage.com sells a dipstick for your engine, because i bought one from them for 30 dollars i think it was. Just type "dipstick" in the search engine on their website and they will have it. One thing that i did until i got a new one, get a couple zipties and a rubber band to hold that thing firmly down on there.

I got a new dip stick I ring and it is still leaking. I put a breather off a 350 over the oil fill. But what about mod to this motor I have another one but I think sealing them wills a pain in the butt. But what are anyone's thoughts on swapping it out? Or just putting performance parts on the motor in the truck?? Help!!

its probably leaking out the dipstick because the baffle in the tappet cover is clogged. You said when it is cold a little steam comes out of the down draft hose and when its warm nothing... I would confirm that this is true and then replace or clean your tappet cover baffle. I have an extra
