What to consider with new cylinder

Servus.https://youtube.com/shorts/pt90Lz5Z0_M?si=fmeDGFsz44-zaj9a Have a Koblenfress, which was to be expected if you offroaded 1000km without air filter. I took my whole engine apart and cleaned it up. But because a lot of the engine has to be cleaned especially with the crankshaft. My plan would now be to tip diesel in and let it work on and then blow out with brake cleaner. I ordered a new cylinder so that it will run again. What so I’ll pay attention to the installation? So I’d like to lubricate it with motor oil and then install it. Anything else?
