PCV rattle 98 JGC 5.2
I noticed a strange rattle under the hood today, the PCV was vibrating
a million miles an hour. It still runs good but sounds a bit different
(other than the rattle). I just replace the PCV a week or so ago. Any
ideas?
Thanks in advance, JK

Re: PCV rattle 98 JGC 5.2
I've never seen it, it's designed to be closed against a spring
with usually a very small orifice allowing what is predicted to be the
idle blow-by to keep a vacuum of clean fresh air in the crankcase. And
opening at full throttle to reburned that larger amount of blow-by. Is
the valve very close to an intake port?

The factory likely forgot to put in the spring or the wrong spring or
something like that. Things 'do' come broken right out of the box.....
