Steel Seal Works
HUOSTON, TEXAS -- 2006 4.2 V-6 Ford F-150
I bought a truck for next to nothing. The prior owner would not pay to have the head gasket repaired or replace the motor.
I used Steel Seal with little beyond instructions ie extra flushing removed thermostat ran with distilled water. It worked like a charm. The engine codes were gone without reset, leak free, compression back, this stuff kicked butt.
