thought i'd take things back to the old school and ask a pinto related question!
on my Indy i have a oil catch tank, cheap ebay thing. got a hose coming from the block where the old kidney box once was but i've replaced that
with a straight adapter that goes to one inlet on the catch tank. the other is blanked off then there's a drain on the bottom of it and a filter
on the top to let it breathe.
other than around the filler cap there's no way for the head to breathe, when giving it big beans it's been known to spew a bit of oil out
around the cap which ends up on the exhaust and causes me to have a twitchy bum. i can't fit a taller filler cap with breather hose as
there's no room under the bonnet, i'm wondering if anyone has put a fitting in the cam cover and ran a breather pipe that way? i'm also
thinking if i can let it breathe better it might stop constantly leaking oil around the cam cover too.
you can buy a oil filler cap with a breather port on it
I think burton sell them
or you might find a cheaper version on ebay

I've seen it done before, a fitting welded / brazed into the end of the cam cover, with something inside to act as a splash guard

chris,
yeah i've seen them like this .......cap with breather
but the one i currently have is like this ..... cap without
breather
there's only a few mm clearance between the top of the current cap and the bonnet so the taller one with the breather outlet will be too high.
i don't really want to relocate the filler to the rear of the cover as i've had it painted to go with my engine bay and want to avoid that
cost again if i can, that's why i was questioning just drilling a hole for something like a -10 fitting straight out of the cover.

I blocked the top rocker breather off and had no problems
you have removed the one way valve from the sump breather haven't you ?
My experience is that pintos really need to breathe. I sealed off the top of my (burton) cam cover to reduce the height of it, and then had a 1" diameter piece take-off point welded on to the front of the cover. I also replaced the breather valve with a Burton valve (which basically is a very low pressure valve). The outlets were t'd together and put to a catch-tank. I would spew oil into the tank if over-filled, but certainly made a difference.
Looks like you are going to have to drill a hole then as suggested
I would look at a 10mm brass plumbing fitting
But I would being a plumber
There are several ways of doing this
Easy way is to cut a hole in the rocker and put a fitting in
The bigger the better for the block I run 16mm from the block
You can run block to cam cover and a separate one from cam cover to catch tank
Catch tank must be vented and the best ones are baffled and have wire wool to desperate the oil and condensates from the gasses
Pinto breathing was a real problem on one of mine and took the fitting of a proper vented tank and large pipes to calm it down

i fitted one of THESE when i did a bit of a overhaul on it a couple of years back, i blew through it both ways before fitting so presumed it had no valve inside it?
i'm thinking of putting the fitting at the back of the cover as there's no direct oil being thrown at it in that position and there appears to be a bit of clearance at the back of the cam?
