1998 Chevrolet Silverado Repair Question
in the oil cap if you have brown andyellow stuff then you are probably leaking the intake gaskets which these are famous for. when you replace the gaskets, put a bead of silicone on the china walls front and back and a little on the edge of the gasket in the corners. make sure you mark the distributor andreset it to the same spot otherwise the engine light may come on due to that being the cam sensor and they can get out of whack with the cranks sensor.
