2003 grand am used engine is different!
2003 Grand Am 4.3
I am replacing this motor for a friend, and her son who works at a salvage yard provided me with a motor. He never said what year, but its identical except for one thing.
this motor has 2 additional (EGR possibly?) rails, one on the front and one on the back, each with its own valve attached to it. They has 2 spots on each rail where they tap into the head. it is looked above the exhaust manifold and runs the length of the motor on each bank.
What i am wondering is this a CA emission motor? and if so can I do anything to make it work. I assume you might be able to just plug the holes in the head and remove the rails, but i want some advice before I replace the intake gasket and drop the motor back in
