    you might have some air trapped in the heater core. touch both hoses when the engine is warmed up, both should be hot, if ones cold or warm. flush it.

    yes 195 t stat is stock. lots put a 180 in there.

    no the cluster gauge is not accurate. use a obs 2 scanner for true engine temps.

    valve covers leak, take a clean rag and run it under the lip of the valve cover, if it comes up wet with oil, bingo.

    Thanks! He also replaced all of the hoses and elbows, so he (or whoever did the work) may not have burped it properly. There was coolant in the radiator, so I topped off the expansion tank. Took about a quart to get it to the full hot line (though it wasn't really hot - kinda lukewarm).
