Hey, i'm lookin at doin my timing belt soon and was thinkin bout doin the cam gears as well, but know s**t all bout them. Just wonderin is there any advantage to havin them on or not, and what the difference is between the intake and exhaust one, since most companys have different part numbers for them. I've found some on ebay but dunno wether to go ahead and buy em or not, manly coz of reasons above
