This occurred to me. I "tested" the crankcase ventilation yesterday by
blowing through the hose connected to the smog canister. It seemed to flow
freely. At first I gave up on this idea but then I started thinking about
the intermittent nature of my leak and figured maybe at times the
ventilation connection isn't flowing freely.
The two wires on the solenoid on the output of the canister are not
connected. In general I'd say the crankcase vent system is suspect.
Perhaps I'll disconnect the hose on the canister and try running it around
that way for a while and see what happens. I'll either find a filter for
the end of the hose or use the catch can method.
