I'm having problems with the pcv valve or something relted to it....I'm getting a rattle sound when I turn off my engine from the pcv valve I replaced it and still have the same problem...is there something else causing this problem taking it to the dealer was no help....need some help with this please

 

I own a 1999 f-150 with a 4.6...I would like to know what the problem might be so I can go back to the dealer and have what ever it could be fixed

 

doesn't anyone know what is wrong...where and what does the pcv valve do

 

located on the pass.side valve cover,center,it removes gases from the block which the engine burns off...it operates in conjunction with the vacume of the engine...are you sure it's the valve your hearing?...if the engines off the vacume is too so you should'nt be hearing anything...you may be mistaking the A/C for that noise

 

Positive
Crankcase
Ventilator

It uses engine vacum to purge engine blowby gases and other gaseous impurities from the crankcase and other areas of your motor.

Its suposed to rattle if you shake it w/ the engine off. I'm not sure about it making any noise after shutting off the engine though.

Good luck.

 

LOL!

Ya beat me to the draw Tex !

 

he's getting all kinds of help now Jerzy

 

I put my hand on the pvc valve and had someone shut off the engine and I could fell it rattleing up and down...what happens if it wasn't hooked up at the other end..and I just recently had my a/c redone had to replace the a/c compreeor and orifues tube could something been done wrong?

 

I can think of drawing air back up through the valve would be the power assist on the brakes....check the check valve on the drum and see if it isn't stuck open

 

thanks guy's for your help I'll take it back to the dealer to have it looked at...hope solves the problem...will this damage anything else?

 

Here is some visual stimulation of what a PCV valve looks like.
Please note this picture was taken with a Webcam, and not a digital camera and that is why the quality is poor.
