    Hey everyone I'm new to this Forum. I was able to buy back back my 1978 CJ5 258 3 spd. The Wife and I dated in this CJ 30 years ago! The owners put a Mr. Gasket chrome breather in the PCV grommet on the valve cover, I order a OE PCV and it has a "T" at the top, 2 hoses. One goes to the air cleaner, where does the smaller diameter hose go? It's a one barrel Carter.

    5.7 V8 with Whipple Supercharger, TH350 w/B&M Shifter, NP205 TC, Dana 60 front 4.56, GM 14 bolt 10.5 rear 4.56, 4 wheel discs, Bilstein shocks, 6" lift on 37's, Autometer gauges, all led lighting and a few other things.
    I think that the PCV connects to full manifold vacuum below the carburetor throttle plate and T's to the charcoal cannister vacuum. A separate vent line goes from valve cover to the filter housing.
    Hopefully someone with a CJ on the forum can verify the connections, been a while since I've worked on one.
