I had the same problem.

The replacement valve had two connections on top. Turns out there is a small plug attached to the valve that goes over the top (Smaller) nipple if your truck doesn't use it.

I argued with the parts guy for about 10 minutes until he took it out of my hand, put the little plug on it and handed it back to me....

" OH.... thank You" :ebharrased:

 

Yup, sorry about the misinfo, I forgot the smaller plug was on top.

 

how do you remove the PCV valve from the crankcase?

 

It just lifts up and out

 

It has always been suggested to me to get a PCV valve from the dealer. The aftermarket valves are pretty much one size fits all, and can cause increased oil consumption.

 

LOL (at myself) THANKS, that "extra" nipple really had me confused! I was just about to go back to Advance Auto myself and chew the parts man out that sold me the PCV valve for giving me the wrong one!

I even ordered the "CD" Chiltons to see if I could get a better description of the location than Haynes or you guys were giving me. All of you (including the guy at Advance Auto who sold me the PCV valve replacement) were telling me the same thing - but I was so thrown off by that extra nipple I couldn't believe I was really looking at the same thing! ROFLMAO!

OK, now, in the Chilton's section on "PCV Valve Removal & Installation" they have a statement "Some models require the removal of the upper intake manifold in order to remove the PCV Valve."

Any thoughts, observations, comments? It does seem very difficult to reach and get enough pressure/leverage to pull it out of that "L shaped grommet" - would using a pair of plyers be unwise?

Also, there seems to be a hose clamp that has been left loose and sort of dangling by some past "mechanic" (or owner as dumb as myself) from the top line - should there be a hose clamp anywhere on the PCV Valve connections?

Thanks again for all your help.

 

I really don't seem to be able to get that bloody thing out. Any of you have to remove the uper intake manifold in order to remove the PCV Valve? This seems excessive so I don't want to start doing that if it isn't needed.

 

There's enough room to get it out without taking the manifold off.

 

After you get it out go to the salvage and find a truck (92 or 93) and use those fittings and connections.

My 92 351w just has a grommet in the valve cover, plastic fitting with L shaped hose coming off that, fits into the grommet in the valve cover, PCV valve fits into that which sits it just to the outside of the plenum then a short piece of hose from the top of the PCV to the plenum.

Still not real easy to get to but not bad at all and definitely not under the plenum. As a matter of fact the plastic piece that fits into the valve cover can be worked out and in pretty easy too once you have the hose fittings lose.

 

On the EFI V-8's you cannot see it. Just reach back under the intake at the rear of the passenger side valve cover. Pull it up and out of the grommet. I do not like the original Motorcraft ones because they are plastic and mine broke into pieces when I removed it. Purolator makes an exact replacement from metal with the correct single fitting.

Disconnect the hose first and then try turn/pull the PCV to get it out.

 

Got it! Thanks guys. It is a Motorcraft and looks nothing like the Purolator PV68C in that not only does it have only one nipple comming off at a right angle, but that seems to be part plastic part VERY short rubber hose which slides over a metal nipple on a metal tube. However, it does read Motorcraft EV-68 - which seems to be the correct number for a Motorcraft PCV for my vehicle, so I guess I pulled the right thing out!

I really was just afraid of using enough "umph" on it, not being certain of what I had my hands on. Thanks for all of ya'lls patience and help.

 

if the pcv valve is non functional, could this cause the filter in the air box for the oil tube vent to become foamy?

 

I was told that I should check / change my PCV valve because my breather filter was oily. I don't know what could make it foamy! But I'd love to find out in case it ever happens to me!

 

Does the use of synthetic oil prevent or preclude the clogging of the PCV?
