White Shepherd Rear Main Sealer (8 oz.)
2002 Ford Excursion 7.3 TD Had a leak behind the motor. I put in 2 bottles of the leak sealer and 1 bottle of the rear main sealer. Took about 3 weeks then the leak started to stop. now it is 95% gone and getting better
works like a champion
Had rear main leaking, very slow, didn't even leave drips on floor, just stained the bell housing enough for you to notice it. Empty the whole bottle in after oil change , and 800 kilometres later its not leaking. Rebuild done 30,000 kilometres and 2 years before. Can't recommend it highly enough
