Hey, fellow brickers!

I just picked up my freshly rebuilt (still in pieces haha) b230ft with slightly oversized pistons. After I assemble it, I don't really know how to break in the rings to the bores. I have seen some really elaborate schemes for breaking it in involving a dozen oil changes, and some others that were more like "keep it under redline for a while".

Also, the machine shop mentioned using high-zinc oil, which is a big deal for the older "flat tappet" engines, but I don't think the b230s are. Break-in oil, I imagine, should be a little thinner than normal running oil, but I don't know specifics.

On the topic of oil, I had been running 15w-40 diesel oil for the cost and because it works well in turbocharged engines and their increased blowby. I need to look at the table in the manual, but I believe it lists 15w-40 for weather over 32F.

Cheers!
