I have an 85 that is totally stock, with 90,xxx miles. Since I have had it I have had to fix a few minor interior glitches, did an oil and filter change, new plugs, wires etc. The car has always ran good, now all of a sudden it has what could be described as a "howling" noise from the PCV valve.
I have replaced the valve and the hose. Checked for leaks, found none. If I pull the line it reads 17# of vacuum at idle. If I disconnect the line that goes to solenoid for the cannister and read vacuum there it is still 17#, but the howling lessens. It appears to be too much pull at the PCV, but why?, and from where? Any ideas anyone?
Thanks,
Bill
