Engatwork,

Thanks for the reply. I did have a brief compression test performed when I was replacing the injectors and every cylinder seemed to pump up to 400+ psi... One of them was a little slower to build than the rest of them but still made it over 400psi... Could it still be a head and/or head gasket problem..? I did see some white looking smoke as I was driving it home but the temp guage seemed normal... It did take a long time to build up any heat in the ACC system...

Thanks,
Marc
