yes i swapped all gauge components from the 91 motor to the 94. there is no oil/water transfer, the grounds are good, ive got 3 22RE trucks and none of them sputter or pull a vacum when the oil cap is off. its been raining all day and havent been able to go out and fiddle. but my plans are to pull the valve cover and run something down the head through the oil ports to see if they are clogged or blocked off by te head gasket.
