    So at some point before i pulled my motor i havd an exhaust leak. I narrowed it down to the heat riser shaft bushing. Mine is gone does anyone know what size it is or where i can get a complete setup. Taking it off all the way is out of the question as it works great otherwise. Thanks.

    That is for a V-8. The repair kit for the slant six, has been discontinued for many years

    No problem. I ordered one for a V-8 several years ago, thinking it would work, for a slant six.

    Try Martin at Arizona auto parts. Maybe Or measure it and find a oil lite bushing that will work. Need to do mine also.

        Just to update if someone ever looks this up in the distant future. On my stock unmodified 63 exhaust manifold the bushing size is 5/16ths I.D X 3/8 O.D fit great just put a little silicone on the outside to hopefully keep it in.

        Yes mine fell out on its own. I was just gonna remove the whole thing but since i drive the car in almost zero degree weather i figured id try and save it.

          That silicone is going to fricker-fry into a cloud of smoke (in the air) and gritty ash (on your manifold) shortly after you start the engine. If you're relying on it to hold your new bushing in placeā€¦it's not going to happen that way.

          Sorry i guess i used the term "silicone" to loosley. It actually rutlands stove gasket cement. Ive used it to repair a crack in an old pot belly stove years ago. Figured if it worked then itll work to hold in a little bushing. Good for up to 2k degrees of roughly 1090c.
