OK, got tired of not fully understanding this birds nest of of a PCV, so I dug into it today (was doing the heater valve replacement and was in the neighborhood, so why not?).

Now i understand the 'heated' valve. Heated with coolant. It yanked right out, pulled the 3 hoses (on a 2000 V10) and sprayed her out with some carb cleaner. Works like a charm (worked ok before cleaning too).

Some pic's below. No, mpg benefit expected.

Really does this need to be heated with coolant???

Does it freeze up on a cold morning? and all hell breaks loose?

YOU HAVE TO BUY A NEW VALVE COVER!!!!

That is unreal......

Thanks,

To get the hose off, You need to reach around it and there is a yellow tab sticking out. catch it with your fingernail and pull it away sideways about 1/4 inch from the connector. Do this while you are pulling them apart lightly.

To get the PCV valve out, it is sort of camlocked into the valve cover. Grab it firmly and twist counter clockwise about half a turn. It will come right out.


I wanted to post this since it is so different from the 2000-2003 models, and it took a bit for me to figure out without buggering up the connector or anything else.

You can get them from Rockauto or your dealer. Napa, Autozone, Advanced, and Pep Boys all said the same thing. No reference for it. Even when I gave them the ford part number off the side.

Here is a pick of the valve:

^ The fitting on the opposite valve cover attaches to the hose that allows fresh air into the crankcase. The circulation of air throughout the crankcase, or "ventilation", wouldn't be possible unless air was admitted somewhere. In addition, under conditions of low engine vacuum (large throttle openings) the blow-by gases that are not being cleared from the engine by the PCV valve are free to enter the intake tract through that fitting and hose on the opposite valve cover. They can then be pulled through the throttle body with the rushing intake air and into the intake manifold, ultimately to be burned in the engine. Regardless of whether we have vacuum or not, the blow-by gases will be burned in the combustion chambers, rather than released to the atmosphere.

housedad's instructions for removal were spot on and the job took only minutes start to finish. Currently Oreiley Auto Parts has the Motorcraft electrically heated PVC for $23.

My oil consumption was pretty significant and when I removed the old PCV, I could still shake it and hear the ball move around but it definately sounded encumbered and not clean like the new one.

I will report back afer a few thousand miles to see if consumption has reduced with just the change.

I usually burn about a quart and a half of oil on my round trips to TN. from FL. (round trip and local cruising about 2500 miles). Highway speeds 70-80mph.

I cant believe I only used up about half a quart on this last trip.

The only engine related part I replaced before this trip was the PCV and the vacuum hoses that touch it.

WOW! Great Info Here!

I was burning so much oil i was getting quotes for an engine replacement !!!!

I had already checked the PCV - it passed the rattle test - but decided to replace anyways as it was $3.90 vs $7000

Guess what - oil consumption dropped to an acceptable level

So I would recommend everyone to swap it at the next service - just in case - what's $3.90.

BTW this is the heated one on a 2001 V10

Yeah, I was sold two smaller, bare metal pcv valves, and told "there are two on that model." Last time I will FULLY rely on the parts guy at a retailer to inform me of what my parts are. I found the valve mentioned above (the larger, blue plastic, twist type), and found that O'Reilly's carries the part for $23.00. I'll go pick one up today. Thanks for the conformation here.

Rock Auto shows the PCV for less than $4. What does O'Reilley's include for $23? Some of the hoses?
