Those are designed to use a rubber grommet and push-in style breather or oil cap. They weren't intended to be threaded. Too thin. You could have threaded bungs welded on, but then you would need to re-polish.
Hi to all, need some suggestions on new valve covers. I picked up a set of ball milled aluminum valve covers for BBC. I set up an external breather and will tap and install A/N fitting to run the SS lines from the covers to the breather. As you can see in the picture, the covers came with a large fill/breather hole that is untapped. I would like to retain this for filling purposes but have not been able to fing a plug for this or should I try to tap it out and use a screw in cap? Toss me some ideas. Sorry NUBSS, I had to do some mods! I will post some pics of the other stuff I have done as soon as I get these on. Thanks in advance.

is it just me, or does one valve cover seem taller than the other?
And smaller too...
You can buy the push in oil caps from Summit, Jegs, etc. I think CP Performance has them as well.
How about this oil filler adapter made by Shogun Ind. (http://www.shogunindustries.com/cgi-...w_item=OC30199)
here is the way mine is set up i think you want the same thing the small aluminum piece is a push in and the other end is a AN fitting just thought might be an idea http://www.hotboatpics.com/pics/data/500/5686DSCN0170.JPG[/IMG]
Looks like a good spot to install a -12 weld bung. Take off the fitting and put in the oil. Keep the covers nice and clean with out the extra fill hole.

That's a cool piece Taylorman. Is it two pices that screw together and doesn't require welding?
Too bad it isn't a breather too. I still use a PCV but would love to ditch my pushin breathers.

It bolts into the valve cover. They also make crankcase evac system that i just bought. Here is a picture. It has the check valve built into the breather instead of it being screwed onto the header. They are really nice.
