Draft Tube To Pcv

    Hey guys, my f134 has a draft tube currently (or I should say before my rebuild)

    Just got the rebuilt engine from the shop and I want to switch it over from the tube to the PCV system.

    I tried doing this before the rebuild, and it ran really bad without adjusting the timing or carb.

    I assume there are timing and carb changes that would need to take place after the switch. Since I am starting fresh, should it be pretty straightforward?

    Not really, if you were having issues I'd say you had an issue with the valve not restricting flow to the manifold vacuum. Were you using the valve on the top valve cover or the side valve cover one?

    If properly plumbed, the only changes you should have to make are idle mixture and idle speed.
