Sons 300m and I need help please!

Sorry for the delay
Due to the need for a vehicle NOW with school and work (my son is in college at the local community and works 25+ hrs / week) we bought a 2003 Grand Am to fill his needs.
In the meantime, the 300 has been pulled into the garage and is waiting for me to pull the intake / valve covers to see whats going on in the top side.
I will update when I get it apart.
First, time for me to update my Yukon Denali. Mine is getting pretty worn and I do not want to be nickel and dimed to death on it.
It will be gone before Christmas.
