Break-in for bearings?

Re: Break-in for bearings? (servion)
the break in is usually for the rings only.......allthough it probably wouldent be a bad idea to take it easy on the engine for a couple hundred miles anyway just to be safe.....

Re: Break-in for bearings? (non-VTEC)
That's what I've always thought.
I've got a good friend who spun a bearing BAD (its torn up, twisted into an s-shape) in his d16z6. He paid them to assemble it with eagle rods, SRP pistons and new OEM oil and water pumps (as well as all required machine work). Now, they're tellng him that they won't cover their work because he didn't wait to get on it until 1500 miles. I call major BS on that one, and I want to make sure you fellow h-t'ers will back me up

Theres a site on breaking in motors, the theory is about ring wear, the bearings arent a factor if the bottom end assembly is balanced which most are if put together right.
But the theory is drive it hard to break the rings in smoother, and change the oil after 20 miles to get rid of the ring shavings from the break in.

Re: (zensoku207)
I agree with that method, too... that's what I've done with the motors I've built myself..... and I've alwyas thought that if clearances are right and assembly is done properly, bearings will not be a problem, regardless of how hard you beat on it.
