My civic is spitting alot of oil out of the canaster underneath the intake behind block im boosting 15 psi rite now i have a catch can off the valve cover but nothing coming out of it oil is all in my motor bay also the air temp sensor on back of intake keeps going out i need some help

 

Let me try to fill in the gapping holes of info here. Is it a b16 block, bored AND stroked to make it a 2000cc motor? Were the pistson designed to put the wrist pin below the oil control ring (good) or above that ring's lowest point (bad)? How many miles? Was it tuned from day one, just recently (how many miles ran before tuned?), or still on a basemap? How is it tuned - fmu, piggyback, hondata/etc? Is the turbo brand new? Any shaftplay at this time (don't assume)? Do you have ARP head studs and are they torqued correctly?

Anyways, sounds to me like your rings (too rich) or ringlands (detonation) are shot. That canister is hooked to the crank, and possitive crank pressure will shoot **** out of it. Motors with very crappy RS ratios (a stroker with shortened rods) will tend to put lots of stress on the sides of the cylinders, which can oval the bores or wreck you rings.

 

assuming your rings are ok, with any kind of power you shouldnt be using the stock box back there. you need a proper catch can setup to get rid of all that crank case pressure, especially with a longer stroke.

only way to know is by checking compression and leak down.
