Hey Scotty, I recently got a 2001 Toyota Celica with 150,000k miles. Sometimes on start up the exhaust smokes a little too much(in my opinion). I've read that in the 01 Celicas they have oversized piston rings and there isn't the piston holes aren't big enough and it gets gunked up. Could I clear that out with the Gumout cleaner?
Thanks Scotty, I love you channel by the way.
