Has anyone remove the stock breather valve and replaced it with a male fitting?

If so, what size fitting would work best? -6an or -8an?






I'm planning on running two 12"an fittings to catch can but figured while I was putting fittings on I might was well do something with the stock breather nipple rather than just capping it off.

?

 

charli theres a few ways to do it also

 

Running 2 -12an lines off the valve cover is plenty. What I do is remove the nipple completely then drill and tap the hole for a 1/8npt plug. Looks much cleaner that way.

Or you could take out the nipple, drill a larger hole and weld a -8an bung on it instead.

 

pictures?
thanks guys

 

I pulled out my nipple and welded it shut

 

yeah that's what i'm probably going to end up doing....

 

Pulled the o.e piece of tube out then drilled and tapped a m10x1.5mm thread to accept an adapter to go to -6.

 

just plug it. a -6 will just make it look more cluttered.

 

Thanks guys pictures will be up soon... lol

 

all done

 

this was my solution

 

damn, that's one good looking catch can

 

what do the baffles look like inside? i would think you would get alot of oil in your catch can. when you run them in the front you want them behind the baffles.

 

I did mine the same way with two -10's on the front, and welded the breather hole shut...

 

i have a small baffle in front of the fittings in the valve cover the catch can also is baffled with a -10 drain to the block so oil in the can doesn't bother me any ways.
This is how it looks now after i powder coated it all

 

if you really want to put an an nipple where the stock nipple is, grab it with a pair of pliers. twist the hell out of it. it will come out.

it is close enough to a 1/8npt hole you can tap w/o drilling.
