Wouldnt I have to still remove the entire plenum again even if I did track it down to the leaking oring? Another thing is it possible that one of the coolant lines under the plenum like for the throttle botties got cracked somehow somewhere causing coolant to leak into the intake? Seems like a HUGE amount of smoke for a pinched oring. Plus it went away for a while, ran great, then came back smoking again with a hesitation like situation when revved up. When driven, the higher you rev it up the better it runs.
