Being that all of the smog equipment is now off of my motor, I have a '74 2.0 air cleaner cover that I want to use because it does'nt have the extra port for the egr. It has a 1/2" fitting and my stock oil breather fitting is 3/4". Any problem with reducing the hose to 1/2"? I also have the additional head vents so I don't "think" it should cause any issues.
Thanks
