Default HELP. Turbo leak!

Ok so i have a b20VTEC in my integra with a junk yard peiced toghter "home made" kit.

I have been burning oil like crazy brand new motor 1,450 miles on it everything internal was machined or new

my breather hose that goes from the valve cover to the intake its not hooked up to anything yet and its just steaming out i noticed just a few days ago white smoke is shooting thru at idle and even more when i give it throttle. I did have bad valve cover gaskets but I just replaced them today. Anyways I noticed everytime I would put my finger on the end of the breather hose oil would just start spilling to the ground from the top of the oil return.

any suggestions? do you guys think its leaking because the crankcase pressure isnt being released? what should I do?

heres a pic to more clarify what im talking about

when you say its conected to your "intake" do you mean your intake tract or intake manifold, or your intake (pre-turbo).

the hose that I have that noramlly goes from valve cover to THE intake. not intake manifold its not connected to anything because i was in a later time going to re route a pcv system that goes from the cover to the induction side of the turbo.

basically in short im shooting white smoke out of my valve cover and when i plug it up oil starts squirting from the oil return. (its siliconed theres no gasket) that CAN be a problem..

A: Go with a Greddy kit next time. Home Made setups are stupid.

P.S. There is no gasket for the valve cover? You're putting in too much wrench time.

its very simple. do you know what a B series valve cover looks like for a honda?

if you do, theres a opening on the valve cover for the pcv. on a stock honda theres a hose that goes from there to intake (to relieve the pressure build up in the motor)

ok I have white smoke coming from that opening in the valve cover and when i plug it up oil starts dripping more and more as pressure builds up.

the area in red iin the pic is wheres its coming from. the top side of the hose where the oil returns to the pan

Never mind, I see now. You blew your JDM motah.


Next time you find your way into a bulletproof ZC from Topgun Motoring out of Palmdale, Ca.

First thing do you understand what a turbo does? You are connecting a boost line to you valve cover! thats putting a positive pressure on your motor How much boost where you running into it. I wanna see you launch your dipstick like a ------- rocket. Block that line off and put a breather on the valve cover

you've got broken ringlands and so you're pressurizing your crankcase. When you plug the vent for the crankcase (hose coming off your valve cover) the only way your pressure can escape is making an exit at your drain line return. It takes a little oil with it hence the oil leak.

Edit: just read that you have a new engine. Looks like something is not so great with that nwe engine if you have a ton of white smoke blowby coming out the breather
