340 oil pressure? Help

So then, rings, valve guides, bearing surfaces,timing set and all the rest of the internal engine parts don't need a break in? Since when did I get specific about WHAT was breaking in? I was simply referring to ENGINE break in.

Whether it has a roller or not is really a moot point. It's still a good idea not to let it idle, as you WANT good oil splash on a fresh engine so everything gets lubricated. At least I do.

But I guess that's bad information, too.
