Ford 2C3Z 9G804 AB High Pressure Ring Review

could have been chosen if there had been an oil leak between the engine and gearbox and it was found that they and the base gaskets were leaking into the engine valley. The filled cavity then drained through the trance into a drain hole behind the cavity, giving me a false indication of a main seal leak. I put my hand in the valley and my fingers were covered with oil.

O-ring kit delivered quickly and as advertised. Well packaged and in original Ford packaging. for your specific year. Makes work a lot easier

Received a day early. The o-ring on the 18mm bolt on the back of the HPOP was defective and oil was leaking into the valley. Received 3 o-rings, a tube of blue Loctite and detailed instructions. If you have 7.3, take them and leave them in the glove box. Can save you days of downtime if you have a factory HPOP with factory o-rings.
