Replacing the PC valve would be my first move and inspect any rubber hoses associated with the valve. Multilayer hoses (if they are used) can separate inside and block the access to intake manifold vacuum.

Line that goes from pcv to carb


It would be called a PCV hose, or an Engine Ventilation hose.
It directs engine crankcase fumes into the carby, air intake system.

99 dodge 1500 p-up-318 block starts fne, warms up and starts to hear air suction sound from under the hood, motor kills and then wont stay started after that...


check all the vacuum lines, and the PCV valve, get a can of carb cleaner, and while the motor is running, spray short bursts of the carb cleaner all around where vacuum lines are located, if the motor rev's up thats where your leak is going to be

Changing PCV valve


you pcv valve should be located on the top or around the intake on top of the engine. It is covered by a little pcv valve rubber hose...it is easy to identify because it is similar to a radiator hose but a lot smaller...no where near the size of a radiator hose...but when located, the pcv valve just pulls out and to check for it being bad, shake it and it should sound like something loose inside the pcv valve (thats a good pcv valve) but what they look like, they should be a silver looking color with a small little neck on it

I am installing a Holley 2818 on my '65 327 and need help with routing the PCV lines. Which line goes to the PCV inlet on the carb? The rear block inlet or the one on the oil filler neck?


On the 2818 holley there is a calibrated elbow on drivers side of carb about centre of the main body.This connects to oil filler stand pipe in front of intake.Fresh air hose goes from air cleaner to back of block where road draft tube used to be before PCV came along.
The calibrated elbow serves as PCV metered orifice.Be sure flame arrester screen is inside of air cleaner on fresh air connection.

Engine pulsates during idle and from second to third gear


Try checking for vaccum leaks, use carb cleaner and spray it around the base of carb, vaccum hoses, edges of intake manifold, take pliers and squeeze the big line to brake power booster & see if it changes, pull the pcv valve out and cover with your finger see if it changes idle.

Engine stalls after cold start-up & release from high speed idle


I had a similar problem.  I found the filter cartridge below the pcv valve had carboned up, and after the crank case pressurized, oil was forced out the pcv supply line to the throttle body.  The idle air control valve solenoid got oil in it and caused my problem, but only when it was cold.  The pcv cartridge is accessed by removing the pcv valve and the rubber fitting that the pcv valve mounts in.  It can then be fished out with a pick set, and it is a pain because you can't see it, but you can get you hand back there.  I hope this helps you.
