- 1994 Explorer Sport
I've had to pull down my 94 Explorer to the block because she popped a coolant channel in the driver side head gasket (no power drop). But I've been cleaning the heads today and I've noticed a white buildup around the middle exhaust valves on both sides. I was wondering if anyone would be familiar with this condition.
Edit: I measured the heads for warpage, found approximately 3 thousandths in the middle. I have a working theory that old gaskets+slightly warped heads= slight coolant leak into combustion chamber.
