im sure they are leaking on bolth sides.but did not bother checking passenger side.figured i will be doing bolth sides as well as a lower intake manifold gasket.might as well. in your opinion will i be better off keeping the thermactor system or will i be better off to do away with it while i have the plentum and intake out of the way. no vac leaks in the system and tab and tad solinoids are good. and i cant seem to find the tab and tad valves new so im guessing they are discontinued.

 

Who me? I'd keep em w/o a doubt. "Give unto Caesar what is his."
In this case "Caesar" is your EEC, & the senor's & actuator's belong to it. Otherwise, you're asking for trouble. Federally mandated to be used as part of the Emissions control system, the EEC there to stay. They can be your worst enemy, or help insure
proper function.
IMHO
