had to replace the engine manifold gasket. also replaced some inlet hoses that later leaked again. however the repair shop fixed this for me free of charge. this was a very labor intensive job that was not cheap, i recommend to save on costs check your serpentine belt and supercharger belt because when your engine is torn apart it may be cheaper to replace these then.
