I have a 1966 289 coupe that was originally manufactured without the California emissions setup. I'm having some oil blow-by and several folks have suggested to me that I ditch the breather cap and go with a closed crankcase type breather with a hose from the oil cap to the air cleaner.
The problem is, I can't find any how-tos online or anybody talking about this mod. How do I modify the existing air cleaner housing or should I just buy a new cleaner with the hose nipple on it already? Also, do I attached the hose from the new oil cap just attached directly to the air cleaner or is a PCV valve or spark arrestor required in the middle?
Any help is greatly appreciated!
