Re: PCV Anyone?

How many of you guy's who've added a PCV valve have sealed the oil filler tube? It won't work correctly if the oil fill cap is left original, as it's supposed to create a vacuum inside the crankcase. (which helps the rings seal better as well) One easy way to modify the oil filler tube is to take the oil filler tube from an Oldsmobile V8 and have it cut off and welded to the stock Packard fill tube, and use the stock Olds fill cap. This will help seal the motor like it was intended if it originally came with a PCV. Otherwise, adding a PCV without doing this is accomplishing nothing other than a vacuum leak.
