1977 Aztec F- Port engine- front nose cowl turns brown from heat of exhaust pipe. we have installed a metal plate to act as a heat shield, but still burns thru to the fiberglass cowl. Has anyone else experianced this issue. We have new engine mounts, so the engine is not sagging but aligned properly.
