just noticed 2 things; first on my 99 PA the plastic end pcs of the LIM gasket are orange, isn't that consistent with the new aluminum style GM gaskets ? I noticed that in the picture showing the new style gasket set.
Also I reread the article an it says "In the later model years (99+), GM went to a smaller diameter (5/8”) EGR pipe that creates a 0.065” air gap between the hot pipe and the plastic EGR bore hole in the upper intake. We are not sure if that is a cure though "
So my car should have the smaller dia stove pipe now correct ? Wondering if the LIM gaskets are already the new style ( note orange end pcs) then maybe I dont need to monkey with the LIM ?
I realize im trying to come up with a way that I dont have to worry about this failing, bear with me my meds will kick in soon !
Never mind first question the orange looks to be silicone not the end pcs
