I posted both sides of the engine
I’m sorry gents. There is NO PCV valve on this motor. The draft tube was engineered out during WWll. On the pax side is no more than a free flow from the valve cover to the intake manifold. The hose appears to be preformed for the application. The brass elbow is nothing more than just that. A brass elbow. See the link. PCV For the F-134 | Old Jeep Carbs LLC
Thank you scoutpilot for the clarification.
I'm not sure I'm 100% agreed with that- that's kinda a funny looking fitting just to be a hose barb. I will agree that either way there's some thing not stock about the whole setup.
The point is pretty much moot though- it's easy enough to trace the issue as being related to the the pvc/non-pvc dooey simply by unhooking the hose & capping off that fitting to see if there's a difference in how the engine runs.
"Pvc" hose, for lack of proper nomenclature, was disconected from the top thing on the motor. Still surges. This is not the issue. Motor still sputters at idle
You'll need to block that hose to prevent the possible vacuum leak, just tape over the end, clamp it shut with vicegrips or stick a conveniently sized bolt in it.
Please squeeze the hose and then run it.
Pulled out the part on the T. Its all gummed up. Cleaned thouroghly with brake parts cleaner. Should there be a spring in there?
I give, what is that sticking out?
Spring & a ball bearing. it should rattle a bit if you shake it.
No spring. Should just rattle around if you shake it...it basically meters the flow.
At least I think there is no spring. That thing doesn't look complete anyway.
Odd, I could have sworn mine has a spring in there
Carb was loose. FML. thanks for the help, and suggestions. Vacuum gauge on pcv valve is at almost 15.
Ill order a new pcv valve just in case
I could be wrong, I always assumed not by the way the ball rattles.
Why would the carb come loose? Engine vibration?
So you were just testing us were ya!
Not tightened properly to start with?
