Ok I pulled the snorkle and removed the honeycomb and looked into the throttle body where the stove pipe comes up...Did not see any coolant signs or signs of leakage,,,I guess this model GM used a smaller stove pipe... I know when my 99 Park Ave burned thru I did this and could see coolant laying inside that the engine was sucking thru the burned hole
Now there is a very slight oil seepage sign where the UIM meets the LIM to the back side right corner of the engine,,but again its slight and the car has just under 80k. I tried to snug up the uim bolts but they are under the fuel rails
