I realize you & bmwoem1 are friends - It's not about highjacking his thread - It's about giving the people reading these threads an alternative to "You need valve stem seals because I (the great bmwoem1) said so" - show me one post that he suggested something other then valve stem seals - He had access to these SIBs a long time ago, why do you think he never posted them - these forums are not his personal advertisement for his side business (it's a little self serving)
