Exclamation this part squeals

i was tightening my throttle cable a minute ago and noticed this little rubber fitting. it squeals when my engine is running and almost seems like its not supposed to be rubber. looks like air is being sucked through it and it almost closes up b/c of the pressure of sucking air causing it to squeal. can anyone tell me what part this is so i can replace it? thanks
and its the rubber hose my fingers pointing to. and i can get a more broad view picture of it if you cant really tell what it is. just lemme know

Crankcase air intake? I don't know what it's called but the hose you're pointing to is supposed to be a metal tube. On my engine, which should still be similar, it feeds from a rubber elbow in back of the left valve cover to a rubber elbow on the right side of the air intake. So it looks like replacement might be simple. 'Course I'm not a mechanic so verify all that first.

That is the PCV line from what he said above^^^. The PCV is located on the back of the left valve cover and it goes to under the TB. Replace the whole line with rubber heater hose. That is a reason for P0171 and P0172 running lean in bank 1 and bank 2.

Sorry and to answer your question. I would replace the PCV and the whole line with rubber heater hose. Good lick.

Follow the line from the PCV to under the TB. There are three rubber elbows. All these rubber elbows will crack or leak easily. Replace the entire line with heater hose approx 24".

The heater hose replacement was Vrod21's suggestion. I'd do a direct replacement with metal tubing and use a spring type tubing bender to create the curve. The metal tubing has a sleeve of black foam insulation on it OEM (original from the manufacturer) to isolate it from other hoses.

It's your choice. Like I said I'm not a mechanic so maybe this substitute is a 1up from OEM approach. Me I'd just rub the elbows down with a dab of belt dressing if I wanted 'em to last!

I haven't seen a newer 4.0l. I assuming Ford got smart and used a metal tube instead of our plastic tubes. If you search around the internet a little you'll see how many people have had problems with these rubber elbows. Them metal tubing is a fine replacement considering Ford seemed to have went to it in their newer models. The only reason I suggested the rubber heater hose is because 24" of it is about $8 plus two hose clamps for $2. You have yourself a great replacement for $10. Mine has worked flawlessly for 12,000 miles now.

so from my understanding, the PCV line is for the oil and gas that isnt burned in the block to get sucked through? i went to NAPA and the guy said the reason the tube thats on there now is bad is b/c the contaminates in the oil break down the rubber. its heater hose thats on it, so i need to replace it with either metal or PCV hose thats specifically made for that

Napa is a good place. They'll set you straight on this. The part is still made from black PVC plastic as Vrod21 had said. I only assumed it was metal since it is rigid and covered with insulation.

The PVC system directs oil vapors and blowby fuel vapor from the crankase into the intake which elimates unwanted crankcase pressure build-up and burns up possible harmfull emissions. The line doesn't transfer any liquid.
