In part 4 of my Cosmo restoration, I continue cleaning the engine components, a task which was started in the last video. It is actually quite involved to clean and inspect the internal engine parts and it can easily take more time then it does to disassemble and build the engine. While I did clean all the parts from the 4 port Cosmo 13B, I will only be using the housings, oil pan and a few other components. The rest of the engine will be the irons and rotating assembly from a GSL-SE 13B.
