Can I plug Oil Fill tube hole

OK stupid question I know this:

I have the tri power set for my truck instead of trying to reinvent the pvc system. I decided that I could just plug the filler tube hole and run stock valve or my M/T that already have the breather and pcv . will this be ok.

 

It's ok by me. You'll likely need a 1 1/4" freeze plug to do the trick.

 

You have my permission. I've seen rubber plugs that would fit. Some say L I O.

 

Yea you can but it looks so cool on there. Fashion you a plug for the tube without removing it. Just put the cap on over the non working tube and only you will know.

 

^^^^^ yea, what he said !

 

Some 60's cars like the L-79 327 used a line off of the oil fill tube as one end of the PCV system. If you set it up that way, you could keep the traditional look and still have the PCV.

 

^^^ and they were available in chrome, with a chrome cap too.
