Hi so i have an 87 Jaguar xjs i bout about a year ago and it has a hole in one of the hoses. I want to replace it but don't know what it does or what its called. Please help. (Not my photo or my car, just the best i could find)

 

That is the extra air valve. Helps maintain idle speed on cold start. The elbow hose is part #EAC 2655 if that's the one with the hole.

 

Baxtor is right, of course, but it's commonly known as the Auxiliary Air Valve....or "AAV".

The Extra Air Valve-- EAV-- fits into the back side of the RH air filter housing. Although, actually, I think there might be an alternate name for that one as well!

A rose by any other name is still a rose hey, but Jaguar do call it extra air valve and the solonoiod valve on RH air cleaner is called supplimentary air valve.

 

that's it! that's it!

Awesome thank you all, sorry it took awhile to post, I've been pretty busy. I hope once I replace it that the problem goes with it. Have a good one😄✌️
