At first Werner thought I would need a new set of pistons and sleeves but after he started working on them he mentioned that it might not be necessary after all. He cleaned all the pistons and sleeves and then he honed the sleeves. Werner then opened the engine and as was feared, the lobes on the cam was worn off.
Except for the sludge in the engine caused by the water everything else looked fine. Werner said that this was the first time in his life where something that looked like a lost cause when he started on it, turned out to be a success.
I left the engine with Werner and he called me a day later to say that he has finished assembling the engine. I took all the tin pieces, generator, replacement exhaust etc. to him so that it can be fitted.
Fast forward a week later. Today 23 February 2015. Oupa's engine is finished and to crown it all off...Werner started it for me. I took a video of the event, the master has done it again. I am overjoyed ....
