[B]Hi I would want your opinion on this post at rcu
I think he does not make any really false statments. Break-in IS about heat cycling. Although I usually never allow my engines to go to WOT in the first couple of tanks, I don't idle them either. Bring them up to temp, let it run for a while then cool down (with piston at BDC). Way to go. I hear about a lot or airplane guys that break-in their engines using the WOT method, and controlling rpm with the HSN, but I always felt more cofortable using a slightly rich setting and staying at, say 1/2 throttle and checking the temps at minimum 200-220 degrees. Simply letting an engine idle through a couple of tanks will do nothing but harming it (for the reasons described in the post).
