Advice on hose from air box to engine.

[TallPaul]

I need to replace this hose. It was too short and cracked on both ends. I wrapped it with emergency heater/radiator hose tape for now and used hose clamps to secure it, but in the long run it should be replaced. I think plain old heater hose would work though there is a 1.5" off set between the two ends. However there is what seems like a restrictor in the engine side of the hose (see upper left inset photo). I don't see that the restrictor matters though. Should I just put in a length of heater hose? Actually it may function fine as is for many years, eh? Also the right side of the hose connects to a box that is second in line from the air filter box. The air flow is below the stuff in my picture. The hose in question is behind the throttle body. Not sure where it goes to on the engine side but the intake manifold must be on the back side as the exhaust manifold is on the front side.

A 'mechanic' told me that there are little 'button-like air filters' that you can put on the end of a hose that is supposed to go somewhere but for whatever reason is hanging free, and will act as an air filter.. is this true? I have never seen, and if so, what is it called?

The problem is not a dangling hose like that. The hose is too short, but seems workable with the clamps, but is rotted and cracked, hence the tape.

Is that a PCV hose? If yes, the restrictor may be important to regulate ventilation flow and may cause a funky idle if removed. Can you check what an OEM replacement will cost online?

You might be able to make heater hose work, if you dissected the old line and re-used that restrictor, but hard part would be getting the bends in it without it kinking on you.

RockAuto maybe?

Heater hose will likely deteriorate in the presence of hot gasses and hydrocarbons. Emissions hose can be bought in bulk.

My goof above. The intake is on the front of the enginenot the back.

Anyway, that hose goes to the valve cover, so must be part of the PCV system. I'll look on line maybe the replacement part is longer. There is plenty of time to get the part as my fix will hold for quite a while now.
