Today I spoke to the owner of No. 158, he was busy getting his engine running again. He succeeded partially, with a lot of smoke and water leaking into the oil. Time to do things thoroughly and take the engine apart. His question was if several parts are still available and if I had pictures of parts of the engine. Yes, I do! During the disassembly of No. 473's engine I took several pictures.
We'll discuss the seals and gaskets later on, first a peek into the engine.
