04 4.6 Where's the PCV valve? Thanks
 

Working on the truck now.
Up next is the PCV valve....But I'm not sure where it is?
There's a hose that runs to each valve cover; Do I have two PCV's, one at the end of each hose?
Thanks

left side,

You should tell us driver or passenger side - "left" side depends on your viewpoint...................................

i figure most people would find that "left side" would mean standing at the front of the truck, sorry............................................. .................................................. ..

WRONG..:rolleyes: :ll:

:lol:

The front of the truck is the same as the front of yourself lol - Look staight ahead, what's R/L ? The vehicle has a front and back, so the same applies.

Now you know what most people know lol.

BTW - The 04 heated PCV would be on the drivers side back by the firewall. :thumbsup:


Gotcha :D

:wave:

Thanks JBrew,
Why is the PCV valve heated?
The replacement one (Standard #V341) is just a normal rattler type.
Is the mount heated?

FYI, yest. I changed oil, Cleaned the MAF sensor,discovered that the throttle body was covered with an oily coating on the inside. I opened the butterfly and the top was coated with blackness. A good deusching with Gumout carb cleaner helped. I thought about removing it to clean it, but took the lazy way out.
I also replaced the fuel filter and serp belt.
I've got the plugs and di-elec grease but that (and radiator flushing) are going to be another day.
Thanks for the help.:thumbsup:

duh, stupid me, didnt realize its a 2004

Do you have an oiled air filter such as a K&N?

Brew, I looked in the Rock Auto catalog, and I don't see a heated PCV valve for a 04 4.6. To the OP - if you decide to replace it, do NOT use anything but a genuine Motorcraft PCV valve.

Didn't all drive by wire models get upgraded PCV systems? - I thought ?

mjb should know be be able to tell us by now lol.

This is probably a 3 valve diagram, I don't have it marked. Yea, I thought the 04's -4six and 5four "wire" set ups were the same.. ??

I won't be getting back to the truck maintenance till next Sat.
I'll post any findings....
Thanks again.
GLC, I don't have a K&N....And what's wrong with using the "Standard" PCV valve?
FWIW,-The trucks running great after the MAF and throttle cleaning:thumbsup:

Aftermarket PCV valves often do not have the correct tolerances. This can cause excessive oil consumption. Genuine Motorcraft valves aren't that expensive.
