Hey there. I know that my o ring is leaking on my 7mgte cps. I was just wondering if I could use any o-ring lol or is there like a special kind. It's just that my Dad has a whole assortment of o rings he uses for random plumbing related things. He is a plumber. So is it a good idea to try one of his o-rings as a replacement? Or is it smarter to buy one from Toyota. Just trying to save myself a couple bucks here and there.
