I just installed my new 14cm turbo housing and Pacbrake, everything is ready for the new custom 4" exhaust but I can not find out how to change the flippin' exhaust springs. I have done it twice on gas engines, pull the spark plug, apply air, and use a spring compresser. Easy enough. Can anyone tell me how to do it on my Cummins, please? I can't wait to get this thing running. Just a note. On the Pacbrake they say to put the vacuum switch on the intake horn, I didn't like the hoses running up and over the middle of the engine so I put mine on the wiper motor bolt. Looks MUCHO better and really fits nicely.
