You can replace it with hose from a auto parts store.

    And, the hose doesn't have to be a solid hose; flexible is fine as long as fits tightly.

You can get pretty much any hose from the auto parts store. They usually have reels of hose, just bring in the old one, have them measure it out for you and cut you a new one. Probably won't cost more than a few bucks.

2006 750li passenger defrost not working

BMW defroster works on vacumm so if you have air blowing from the dash vents when the seclector is on A/C and when on bi-leval the air comes out of the dash vents and the floor vents then you have a vacumm leak most likely a vacumm hose is off, Or due to the age of the car the engine heat causes the hoses to crack and break. the BMW V-8 engine has a problem with the rubber holder for the PCV valves cracking and leaking that causes very low vacumm pressure also check all of the vacumm lines that go through the fire wall most likely your problem is just a disconnected or broken vacumm hose or the PCV valve holders.

Check engine light on OBD 2 reads PO 2189, want to know how to repair l

This error indicates too lean a fuel mixture is being delivered to Bank2 (bank of cylinders closest to the front of the car.
This could be caused by a defective IAC valve ( Idle Air Control) but more likely is bad vacuum hose or PCV valve
Check and double check then redouble check all hoses for cracks or leaks. Replace the PCV valve ( about $10)

2005 ford escape problem. Check engines light on. With a hissing and thumping noise around the intake manafold and pcv valve.

Check the hose the connects to the PCV valve. It sounds like it may have a crack in the hose. The heat generated from the engine will cause these hoses to break down and become brittle. Also, check the other hoses around that intake area, there could be a hose off. You can try using a soapy water mixture and spray it on the hoses and it should bubble. The crack very well may not be seen by just looking at it. If it's cracked near the end, you may have enough of room to cut the bad off and use the hose until you can get another. Good Luck.

Changed plugs,plugwires,discap,rotorbutton. and engine still does not run smooth/please help,,

is your check engine light ON? Has your timing belt been changed? have your intake cleaned, including the IAC valve. Inspect your intake hose for crackes and leaks(this is very typical. If your intake hose is cracked or leaking, this will cause hesitation and rough idling/running. post comments or questions...hopefully this helps

Where is the pcv valve located on a 2003 ford ranger

  • The PCV valve can be located in several places. The most common location is in a rubber grommet in the valve cover. It can be installed in the middle of the hose connections, as well as installed directly in the intake manifold.
  • Once the PCV valve is located, make sure all the PCV system hoses are properly connected and that they have no breaks or cracks.
  • Remove the air cleaner and inspect the air and crankcase filters. Crankcase blowby can clog these with oil. Clean or replace such filters.
  • Oil in the air cleaner assembly indicates that the PCV valve or hoses are plugged.
  • Make sure you check these and replace the valve and clean the hoses and air cleaner assembly.
  • When the PCV valve and hose are in satisfactory condition and there is oil in the air cleaner assembly, perform a cylinder compression test to check for worn cylinders and piston rings.

    Check engine light

    O.k. This is generally caused by the mass air flow sensor, that's always first. There is a small belt driven air pump that has a couple of hoses that come off of it and route to the intake (or to the top of the engine) and the exhaust, there are in line check valves on the hoses. This system directs air either to the heads or the cats (catylatic converters). Check to see if the pump has gone out, a check valve is stuck, a hose has collapsed or is cracked/broken allowing air to escape, or if a vacuum hose, that runs to it, is cracked/broken or come loose, and sucking air. This is just an emissions requirement, and when this happens it generally doesn't make the car run any differently, it just throws a code. CHeck these and let me know
