Well, thanks to all the good advice and research about the v8's and e34 I bought a '95 530iA with a newly rebuit eng/head and want some advice about breaking-in the new engine. Any advice/ref info. on break-in for a fresh rebuild on a BMW engine?

As always, thanks for the great info.

Just be nice to it for it's first couple of thousand miles. Rev's quickly to and past 4k RPM are generally hard on it when it's still fresh.

I don't know how necessary it is, but many people like to change the oil after the first 500 miles of a new / newly rebuilt engine.

So gentle drive habits for a couple thousand, huh? I expect highway passing(kickdown) is not preferred or minimize that kinda loading? What about oil change intervals for the first few thousand...any comments on weight & period?

Right, it's been changed in the first 200 miles.

I'd adhere to the break-in procedure for new engines, as described in the owners manual.

That means, go no higher than 4000 rpm, no kickdown, no driving at neckbreaking speeds.

Its ok to rev You just dont want to seat your valves at 6000 RPM Quick shots of throttle ARE ok. The engine should just spend most of its time in normal driving RPMs so all your clearences are set correctlly.

I suggest changing after the first 1000 Miles, and then 3000, followed by 5000 from there on out. That motor is built for it. (why do you think it takes 8 quarts? )
