My 2008 TBSS has 70,000 miles on it and I developed a engine noise . I was told it needed new lifter and paid a shop in Phoenix Arizona to repair it. When I got back it sounded the same as it did when I dropped it off. Before i had the new lifters installed. I was told it most likely was the oil pick up o-ring in the pan. I had a shop in Tempe Arizona do that repair. I am not sure what else it could be now. It have not drove it in 7 month and need to fix it ASAP. Let me know if you have any idea of a shop or person in Phoenix Arizona ( east valley Gilbert, Chandler, Tempe or Mesa ) that could repair it right.
