SR20DET crankcase ventilation fitting - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I'm getting a catch can, and I want to convert all my ventilation lines to AN braided hose so that they don't burn up.

From what I read, you can just pull the valve cover Tee out (it's an s13 blacktop) and run a 3/8 NPT tap through it.

But what about the hose that goes into the block? If I remember correctly from when I did my rebuild, it's a nipple fitting pipe, that goes into the block underneath the head. You can't remove it without taking the head off. Also, tapping it would be extremely risky since it's a channel in the block that goes down to the oil pan. If I tapped it I would have to separate the head, block, and oil pans.

I've seen pictures before with people running an AN hose to down there behind the manifold, but I never could figure out how they did it.

What about cutting the nipple off the fitting, flaring it, and using a flare fitting?

This is the fitting I am talking about btw.

Nikzilla · 07-18-2014, 01:18 PM

Sigh. Doed anyone at least know what size the hose is?

Weld on a fitting ?

Nikzilla · 07-18-2014, 02:17 PM

Can I do that without splitting it?

I haven't tried but I thought that was what people did to convert it. Depends on if you can get a welder in that area. Is the engine in the car still ?

Yeah but I'm gunna be pulling it soon to swap my tranny. I can't weld yet. I outsource my welding to a local machinist.

hey wanted to bump this up. So what are people doing at this piece? I have a AN fitting on the valve cover side and the other end just slips over the pipe. Just wanted to see if there's a nicer solution

EDIT: I see these pieces available but they require removing the head to install
