I’m here in California, took the 85 ram charger down for smog and failed. Apparently the port on the intake where the EGR valve goes is totally clogged with carbon. They just called and said they want to take the intake off in order to clean it out properly. I’m wondering how difficult this is or if it’s just cheaper to buy a new intake manifold and if so which one I should get? I’m definitely familiar with the engines so taking the intake off would not be a problem however if a new intake manifold would be better I would rather do that.
