If anybody finds their pcv elbow on the back of their intake is bad, I found one in the "Help!" section at the parts store. It's just the elbow and is about 10 bucks. Cheaper than buying the whole tube assembly from Ford. The Help part number is 46017.

 

Ford also offers the elbow alone.

F65Z-6762-BB. Cost is about the same.

It's always good to have choices.

Additionally, others have reported using a 90 degree spark plug boot as a replacement.

Good find

 

Yea , good find! BUT, you can order just the elbow, like Steve said..

 

If this elbow is bad what will it cause the truck to do?

nutshell'd, run crappy and make you mad.

 

trying to trace down my vaccuuum leak and it's getting my nothing but pissed lol

 

It will throw codes P0171 and P0174.

 

lol forgot about that one, i have both... but why fix that when i got a whole 5.4 with lightning intake sittin on a engine stand

 

my truck just through those codes and they told me when i throw those 2 codes together mean
#1 is replace the o2's
#2 Replace/clean MAF and now i see this.
When this ice storm clears up i will take a look at it.

Would this cause the truck to idle funny once it heats up because my truck only dose it when it heats up.

 

It's NOT the O2's..

 

lol wait i dont remember my codes very well but 171 and 174 is lean and rich? cant be!

 

Crap!! Your right!! I didn't notice that . Mannn, that's one f'ed up truck

 

yeah mine said bank 1 and bank 2 o2's lean codes P0171 and P0174

 

That means the O2's are DETECTING a lean condition that is beyond correction parameters - the O2's are doing EXACTLY what they are supposed to do. This is usually caused by a vacuum leak that is sucking unmetered air into the intake system.
