If you do the "Hard" way shouldnt you also do an oil change real soon around 600miles/1000km to get the metal out?
Thanks
That applies to a new or rebuilt, never rotated engine.
In this case, what Ive done and always worked for me:
1. Its good to keep it idling for a few hours a day for a couple of days, check for noises, oil pressure and water temps;
2. Check and change oil. Rev it up to 3k for a couple of seconds and lsiten to clapping noises (rod knock, cams, etc)
3. After that, drive it normally but dont rev higher than 3K rpms for the first few days, then 4k rpms for a week and change oil. Start spooling the turbo, a couple of psi's will do fine.
4. Drive normally for a month. Boosting and stuff, change oil only if necesary. Do a leak test on cylinders, inspect sparks and stuff.
5. Drive hard...done
Always use premium gas to prevent ping, always checking for noises, pressure, temps, etc.
And thats true about the ring seals, you will have blowby gases in the first hours of the engine life, but rings are not everything. I do all of this because of the oil seals, bearing and cam clearance.
