Late Valve cover upgrade, CCV update

So, my '88 has always got oil into the intake hose and air filter, even when my dad bought it in 1992. I did Cruiser 54's breather update a few years ago, but didn't notice much difference. The hoses were not plugged. 

I finally bought a newer valve cover and also added an Amazon cheapo oil separator. We just finished a 2200 mile trip and the oil consumption looks to be about 1/4 quart. Previously it would have probably been 1-1/4 quarts. A huge improvement!

You might try a restrictor in the tube going from the front tube to the silver air tube.

It's working the best that it has in 32 years, I'm kinda afraid to mess with it! The front is just a fresh air breather into the crankcase, not sure if a restrictor would help or hurt? There is a small orfice built into the rear elbow to restrict the size of the "vacuum leak".

You might look into the CCV tube. It was 'upgraded' in the latter years. I am not sure if in '96 or latter. I know by '00. The fitting ID is bigger too.
