i have a 00 gt with a s-trim vortech supercharger, well lately the motor was smoking like crazy!. then it started misfiring too. so i pulled the plugs, and two of the electrodes were broken off. now before this i had a lower end knock, now i did a compression test on it and cylinder 4 has a dead miss. so im almost done getting the engine out,. any ideas on the timing chain, do i need a special tool? looks like its pressed in.
