My car has 47k original miles and last year it developed a slight by annoying exhaust leak. It is leaking where the shaft of the heat riser valve comes thru the exhaust manifold. Is there a sleeve that is cut to go over the shaft and into the manifold or any other ideas......Thanks

P.S. the heat riser still works

 

i hope so mine will need the same thing .it's leaking at the seal so bad i can't tell if the shaft is leaking.
