pcv valve question

I hooked my two pcv valves together into a fuel line "T" so they vented at the back of the motor under the truck. But then oil started coming out of the dipstick hole like i am building up way too much crankcase pressure. Whats going on here?

Pcv stays closed till you open them with vacuum. You need to hook one to the big manifold vacuum port on your carb and put a breather on the other valve cover. You gotta draw air into the motor to mix with the oil vapours and pulled out with the pcv. You're lucky it was only the dipstick.

You don't need or want 2 PCV valves. You need 1 PCV and 1 breather in opposite valve covers
