exhaust burbling noise and PCV 120-130 1967

It finally got warm enough in my garage to add a PCV valve, from the dealer, and stick the other end into the carb. It works!

But when I rev the engine up to about 2K, the hose from the air cleaner to the oil filler cap starts to lift up at the cap. At about 2500+ rpm, the hose goes back down. There is no clamp, and it does easily come off. Is this right? Or am I missing something?

The second question is a little strange. Regardless of timing changes, the exhaust burbles with an occasional putt. I adjusted the valves to spec and they appear to be good. Plugs are new, gapped correctly, but not resistor type. I tanked up with 89 octane last October, but it did that with 87 octane.

Otherwise, if the roads weren't grey with salt, I would be out driving it! I can't wait until April :)

    Klaus,
    I'd czech the valve lift. Li'l Red did that when #4 exhaust lobe was doing a disappearing
    act.
    ¿CA?
    Thanks,

      I'll check them again. One was real bad when I gapped them the first time.

      It is so much more fun working on this little 4 banger than the 6 cyl 164. A lot more simple than the 'new' stuff. I am creating a substantial list of needed parts for Spring.

      It is supposed to get back to winter tomorrow, so I guess the frost on the inside of the garage door will stick around a bit. I am tired of chipping the ice off of the garage floor.
