Recommend switching the PCV valve to a "Breather cap / PCV valve" It's a breather cap (with wire mesh in cap) plus a pcv valve. Available at Autozone. Fits right on the ol' 258.

Mine works great.

Hope this helps.

Do you mean something like this?

I might, maybe, have a similar problem, and I know the PCV valve on my 258 is getting old.
