Problem with 225 in my New Truck

How about you put a vacuum gauge on it first?
Check the idle-vacuum in the manifold, and compare it to the vacuum at the PCV port on the carb.
Then rev it up to 1500ish ,using the fast idle cam, and repeat.The second reading should be much higher, but the comparison should still be the same.
If each comparison is the same, then the port may be clear. Now you need to make a judgement call as to the flow. That PCV does not normally flow a lot of air, as the area of the orifice is quite small. The size of the hose and port is somewhat deceiving, being many many times larger than it actually needs to be.The idling engine should stall if you pull the hose off the port at the carb.
And finally is to prove the hose is clear.'course you could probably do that first,lol.
