Chevy Chevelle

How do you prevent oil from being sprayed from the air breathers on your 1970 Chevelle SS 454 valve covers Would a PCV valve help and if so where should it go?

I have had big blocks since I was 18 Im 57 now still a gearhead

. Have seen this prob. Do you have aftermarket valve covers ?

Factory ones have baffles and good ones have baffles .Cheap ones

will do nothing but blow oil out total JUNK . My saying I live by

is PAINT AND CHROME WON"T GET YOU HOME ! If you do not have a pcv

valve you need to install one . Good luck ! No subs. for cubes big

blocks rule !
