I just realized that my cat has a part that is hold in place by a piece of laundry wire...

what is this part, what does it do and where can I find it?

 

?? Looks like a luggage label to me. Used to identify luggage. Any stationnery supplier should do.

 

Someone is messing with you, NOT a part number from my Jaguar time is Spare Parts.

 

Interesting... is this piece OEM in the 1994's XJSs? does it help performance?


oh... I'm sorry... I didn't realize I posted in the comedy section of the forums...

Is that the EGR vac?

Thanks

 

Ah sorry about that Rama, EGR vac yes. Can't see how it helps performance but apparently it is used to recycle unburnt fuel back into the system rather than dumping it.

My 92 does not have this system, one less thing to go wrong.

I do suppose that it should be attached with something more than bandage and laundry wire.

Someone will be able to offer a better explanation, I hope.

 

Yup its the EGR. It recirculates unburnt gases from the manifold for better burning of spent fuel, and emissions gubbins. But these do tend to get dirty and it will be most noticeable at idle under 800 rpm. To make your engine idle like its fresh from the factory you can clean the EGR, because it builds up a lot of carbon inside and restricts flow, thus rough idle.

You have to remove it to clean it.

For anyone who wants to know the steps on cleaning the EGR its here:

1. Fill the EGR valve opening with carbon cleaner. Fill up the valve until the cleaner comes out of the top of the valve opening.

2. Let the valve soak in carbon cleaner for at least eight hours. This will loosen the carbon built up on the inside of the valve.

3. Dump the carbon cleaner out into a container approved for solvents.

4. Finish cleaning the rest of the carbon out of the valve with a wire brush. Most of the carbon should come off rather easily at this point

5. Wipe the valve with a shop rag and allow the inside of the valve to air dry.

6. Reinstall and your done! Idling smoothly once again

 

Now I see it, fair dinkum, yep EGR valve. We DONT have them down here, less things to go wrong. Some of the real late V8's have them, but after 2 years they are toast and no-one worries about them. reckon we got it easy in the colonies,mmmmm.
