If you find an additive that works, you rich! I dont know of any but then i have not tried any either. WTH, wort a shot! -
Answer 2
I know this is a post from last year, but I just had mine quoted at a local reputable shop. $3,500 for new valve guide seals on a 2006 550i. Problem is the labor. I was told it takes about 30 hours plus parts. Still, Ouch! -
