Hi
Can some tell me when GM started factory installing the redesigned lower intake manifold on the 3800 engine?, the one with the smaller diameter EGR tube to prevent the upper intake from failing.
I think I saw a post in the summer, stating that it was possible that the 2000 models came with the new intake. I have 2001 Buick Lesabre and would like to know if mine has the updated version.
Thanks Ted M
