I bought a Prothe engine gasket kit and a timing belt tensioner (didn't buy his timing belt) before I knew any better. This was 3 years ago when I bought the Eco diesel. I threw the tensioner in the trash but still have the gasket kit which has all the seals and gaskets except the head gasket. I am putting the head back on and was wondering if the inlet and exh manifold gaskets and the cam seal are of good enough quality or should I buy new ones? Anyone with actual experience with that gasket kit want to comment?
