I have decided to do major work to both my engines (Caterpillar 3208TAs) this Winter. They are almost 29 years old and have almost 2000 hours. I'll be replacing head gaskets, rebuilding the injection pumps, having all the injectors tested (and rebuilt if needed) replacing all the hoses and belts, and replacing all the gaskets and seals I can get to without pulling the engines out. Will also clean and re-seal the oil coolers, heat exchangers, and after coolers, repaint everything I can, and will be adding Walker Airseps (PCV systems that collect and condense oil vapor and re-route oil back to the crankcase instead of into the engine air inlet where it can clog the after coolers). I got the heads off engine 1 yesterday and it's in great shape. My goal is to have the engines operating trouble-free for the next decade or longer.
