Can someone please identify the oil fill cap in picture. Need part number if possible or how to fabricate one. Much appreciated!

 

pic is small, but it looks like a stock cap with an AN hose fitted into it for some reason or another..

 

Sorry for small picture. I agree, stock cap with AN fitting. Just trying to figure out how to fabricate or buy assembled if possible.
Using line to run back to inlet of blower intake to alleviate blow by.

 

Honestly just looks like a cap you get with a bypass oil filter system.

Look into AMSOil Bypass Filter Kits. Maybe give them a call for just the oil cap???

This shows the oil cap I'm talking about. Look into the universal kit if need be.

It's always easy to find pictures of these things in the...Tuner sections of the internet.

 

a line from the fill cap will bring a lot of oil with it since it isn't baffled.. if hooking the stock breather tube to the blower inlet doesn't do the job, then you need to tear the motor down and rebuild it.
