I have had this p0442 code for a while now. I just built a homemade evap smoke tester and used it today. I found smoke coming out from this square shaped canister that is behind the coolant overflow and it has a 2 wire plug and a fairly large hard plastic hose on one side. My question(s) is what is it called and is it supposed to be leaking smoke/vapor?

 

I would like to think that the British would'nt have designed something that is meant to leak but.. Land Rover.

 

You can get the same part off of a Chevy Express Van for 15-20.00. It’s a purge vent. Haven’t smoke tested one before, I have had one fail. I got my replacement from Advance Auto.

 

Do you know if this is the right one? A Dorman 911-074?

 

 

is there a cross reference sticky?

it would be really nice to have that.

as long as someone else does all the work to find the parts and i get profit from their research.
