Yes, unfortunately, my research shows no aluminum alternative manufactured for the 4.2 at this time. I was finally able to track down a used OEM. The AJ89486 shows as discontinued so an aftermarket one is likely in works. I didn't have patience to wait around

 

Did anyone come up with a workaround I have a seeping t-stat column could I take the column piece from a 4,0 and use that

 

Have you tried ebay?

 

I just called Jabbits and ordered the part

 

I hope it's not the same one listed on ebay for $86. Please let us know if it's a genuine Jag part.

 

I bought one at jagbits. All the other sellers have the wrong description

 

The link takes me to an Exhaust Gas Valve for a Volvo.(?)

 

I have a 2005 xk8. I am replacing the Coolant system hoses etc I finally called jagbits they reported they have the Correct housing. It arrives tomorrow
