It's Brent again here, I finally replaced my valve seals on both cylinder heads, they were basically shot and came apart in little pieces in my hands.
We cannot blame Auto-Rx because I started using this product at 343,000 miles and my valve seals were probably done. There were a few seals that hardly had any material on them.
The good news is that since I am running a Maintenance Dose of Auto-Rx the seals will stay soft and pliable and not deteriorate, this statement was made by someone over at BITOG who has a lot of knowledge about Auto-Rx and engine oil's and always tells me the truth.
I am just happy that I will not have to replace valve seals again and I am happy that I am using Frank's product on my 2004 Mercury Marauder and on that vehicle the engine is running fantastic, and the credit goes to the Maintenance Dose of Auto-Rx.
I am wondering if my oil filter issues on my El Camino that now has 365,000 miles was partly because my valve seals were shot, I do not know, all I know is that I will continue with the Maintenance Dose for my El Camino and Mercury Marauder.
