Had a laugh on that. Ideally it's true and then I think of the work that happens mostly on bikes in the middle of the Dakar and others, work I and others have had to do on site and the list goes on. Cleanliness is next to G...... as they say, but knowing what needs to be perfect and what doesn't is the key. Many engines run their whole life with swarf without anyone ever knowing. But if you don't scrub the whole block after a hone you're in trouble, do the bores twice.Mɐʇʇ wrote: ↑Wed Apr 21, 2021 9:54 am.......................................
@Tony : As we often do, we've disagreed whilst agreeing.
I view anything properly in the guts of the oil system as a bit like open heart surgery. 1 bit of grit or swarf is enough to ruin the expensive rebuild.
So while I said "clean room", I use those words to highlight that cleanliness is next to godliness when it comes to engine rebuilds, not that specifically, it has to be a hermetically sealed clean room. It's all just risk mitigation to avoid having to do it again and the average mechanics workshop I've been in is not clean enough IMVHO. And since this is the internet and things get quoted, I prefer to overstate rather than understate important things.
Pretty clear that it needs to be a replacement engine to be viable under the circumstances put forward. Worth getting the bearing topic updated though as sooner or later someone will need it.
