A 85 Westy 1.9 with auto, a/c & power steering. Is it possible to have  vacuum leaks at the base of ignition distributor and the crankshaft pulley bolt key way? My mechanic did a smoke test for leaks and found them at these areas. He also said the heavy washer that goes between bolt and pulley is missing. I thought a/c & ps pulley bolt didn't have this washer. Anyone have experience with this kind of leak and the lack of washer? Thanks.
