Break In period?

I've got new rings and rod bearings going into my car. Does anyone know if there is a break in period for these?

 
i assume you honed. if you did:

beat the (@#&@#& out of them for the first few miles or so, then oil change @ 100mi, then baby them for the first thousand.

 
Thanks, I did get it honed. Is there any specific oil, i've read to use regular oil opposed to synthetic. I usually use AMSOIL but I don't feel like throwing away 40 dollars in 100 miles.

regular dino oil works great. When you change the oil @ 100mi, run dino in that as well. I'd say you'd be safe to switch to synth after 1k. I use amsoil as well and it works great for me

To properly seat the rings get the engine running but don't idle it any longer then neccicary. Get it out on the road and drive it in 5th gear at lower speeds to get to zero vaccum, accelerate for a short period at lower rpms at half or more throttle. Then come completly off the gas to get the engine to pull the maximum amount of vaccum on decel. Then repeat the process for at least 20 miles, always changing rpm between zero vaccum and full decel (down a long hill is awesome)

If the rings don't seat properly in the 1st 100 miles, they will never seat because the ridges created by honing will be smoothed over.

I broke my Accord engine in this way and after 3 years of 500 hp rapings on the rev limiter every day it still has 2% leakdown on all cylinders.

 
there is break in oil you can buy. I think Royal Purple makes some. It's pricey if I remember right though. But specifically designed for it though.
