on my old 1980 bus, when they told me how much that tiny little valve was
going to cost, i backed out and rethought this process. finally i  decided
to just block it off. i made a flat plate that cover the valve position
and bolt it in place with a gasket. for the exhaust pipe end of the little
pipe, i had it welded closed.  that was back in about 1985. although i sold
the bus (weep, sniff, boohoo), it's still running around town here. total
cost? about $20.

now that is in Alabama, which has virtually NO pollution laws, and absolutely
NO pollution tests (if your smokes really badly, the cops figure you are
killing mosquitos and leave you alone).

i never noticed any rise in temperatures of the engine or the exhaust or
any more rapid wearing-out of the exhaust pipes or mufflers. but then i
only put about 70,000 miles on it after i made that change (before i sold
it).

probably doesn't have anything to do with anything, but i told i'd tell ya.
