617 Turbo Diesel Loud Engine Rattle Noise

Common problem due the failed air cleaner mounts and mounting bracket

If your 1978 to 1985 turbo diesel 5 cylinder engine has a loud rattle near the valve cover most likely it is coming from a loose air filter housing. Just grab ahold of it and shake or lift up on it. If it moves significantly then something is broken underneath the big round housing (this only applies to those engines that have the air filter mounted on the engine - most 1985 models have it mounted off the engine behind the right headlight).
