On my 99 Si, I had two -12an bungs welded into the valve cover to vent crankcase pressures. I thought the s2k (my ignorance) would be ok, as we already have 2 bungs, albeit smaller, I figured it would suffice.

Well, after a few pulls, I'm seeing my dipstick pop up a little..so I know I'm exceeding the limit of the factory system.

I've already got a small air filter on the first bung off the valve cover, and a tiny can on the 2nd one, closest to the firewall open to atmosphere.

I was thinking of pulling the pvc valve and hooking it up directly.

Thoughts?

 

I have 3 bungs welded on mine.

 

Pics of this please!

 

A quick fix for the dipstick is to turn it around 180* and that will keep it from popping out. But youre right, the real issue is crankcase pressure. Kutsujula had a T1 race parts setup that was real nice, like he said 3 bungs off the valve cover. I want something that will work but isnt real huge.

 

Here's my setup I threw together. Going to make a nicer one sometime down the road...

 

 

That looks nice!

I went with this from ATP Turbo.
Routed both valve cover hoses to it. No IM return.

 

Oil catch can / coolant reservoir combo

 

dual can setup, 2nd catch can ordered, will replace this one,

 

Mine isn't vented because it's used as a oil separator on the PCV line. It was made from a A/C drier on a 96 Odyssey.
