I'm trying to help my brother out with his truck. He get a UOL with every OCI. They keep telling him that his silicon is high. We both live in Florida. I told him to check his air filter(Donaldson). He said it looked like it was sealing ok. He had an in-frame o-haul about 80,000 miles ago. Could gasket material still be leaching into the oil? I thought I would post his last UOA numbers to get some feedback.
