PCV issue

Thanks for the info. Jon.

I'm gonna let the others speak to the carb. They'll know more when it comes to getting into the idle circuitry, etc.

Looks by your vacuum readings that you have a fairly mild cam. My only concern is the lash settings may be a little tight. Especially the intake side. 67gt also spoke to this. I would loosen them up a hair and see if it helps. Wont hurt anything except maybe a little noisier. Maybe .016 int. & .022 ext.? You could probably even go a little farther but i would start there and see how she does.

Oh yea.....Nice Valiant!
