A fair bit of time yesterday was spent prepping the Ducks original engine ready for rebuild(draining of fluids, cleaning and removing old gasket material). Today, I went to advance to removing everything that didn’t need to be on there (heads and such like) only to find cylinder no 4 has a severe wear groove in the cylinder wall. I now have two choices. Get a new liner fitted which means crank and pistons out which is something we wanted to avoid or start the procedure all over again with another engine. The next engine is on the bench waiting for me to finish my (very much needed) cup of tea. Here’s hoping this motor doesn’t have the same damage.
