PVC vacuum lines sucking closed

[dany10boy]

Anyone know why vacuum lines to pcv would be sucking themselves closed..... Vacuum leak??? My car sounds like a tea pot!!!!!(boom01)

Are you getting oil out your crankcase breather hose.

Ive got a honda with that problem. Its got 360,xxx miles.

Excesive blowby closes the valve, and the intake manifold sucks the hose flat.

you probably just need a new valve tho.

if you put your thumb over the pcv opening (engine running/teapot mode) and it stops - replace the pcv

Looks like the pos hoses just got soft. Have to find some decent line somewhere.
