I have been reading threads and asking around about the engine break in time for a new 2005 Corolla XRS. People are saying all different types of things. What does everyone suggest? The dealer is telling me 1000km. I read another thread on this forum that mentions 2000km. Others say you should gun it then lets the engine kewl and do it again and again. My 2005 XRS has 350km on it and of course I couldn't wait to take it for a spin. I pushed it a little bit but not too bad. Lets say I was doing around 5K/RPM in 6th gear on a straight away strip ( I did not break more than 4K/RPM until I hit 6 gear when I then went up to 5K/RPM's around 100mph). Do you think I messed anything up? I have not done any off the line racing in it so I never really pushed it beyond 4K/RPM except on that one occasion.
Also, I noticed a clicking sound from the engine that kind of makes like a slight air shooting sound? Is that just the injector?
Usually it is around 2000 KM or so according to the user manual ( you are in US so I would have expected miles from your mouth. )
Although, my Toyota dealership told me not to baby too much and in order to properly break in I should "occassionally" use the full rev range right up to 8300 rpm or so. One thing that you should not do is put cruise control on a highway or drive at the same speed for too long. I am sitting now at 1940 KM or so and I must have hit lift about approx. 20-25 times.

Ok he knows what he's talking about, listen to him.
You'll notice a difference in power at around 5K miles when it frees up a bit, until then I'd just avoid hammering it from a dead stop, or buzzing the revs when cold which I'm sure you know about anyways, otherwise just drive it normal.
When I rebuilt my first engine, I was real easy on it, wasn't until I loaned the car to someone, a couple years later, and they thrashed it HARD, did it finally break in.
I was talking to some motorcycle racers about this; they seemed to have it down to a science. They would go out for a ride, load the engine pretty good, third gear pulls, as the engine was about fully warmed up, but not all the way to normal operating temp.
Then they'd cruise, stop for coffee, let the bikes cool, do it again.
Oh, another thing, my car started life as a rental car, makes pretty decent power now (150K)after some mods, tuning, burns no oil.
I have hit lift about 20 times or so and revved up to 8500 rpm about 20-23 times in the first 1950 KM since I could not resist temptation. What will be the side effects of this??? Will it affect the performance, the refinement or the smoothness of the car??

From what I understand, you won't exactly kill the car accelerating like that not so often. Nevertheless, keep an eye out on your oil, who knows, you may even want to change it a little earlier if you're running it harder then usual. Many times, from teh techs at my dealership, it's the consistency of running the engine hard that just does it in. and our place should know, so many Celica GT-S' come in for new motors.
The techs tell me they check the codes, and some people just run the things so hard ALL the time. Apparently, I found out that the ECU keeps some kind of record when you hit a very high RPM.

I drive the car with great care and do not abuse the tranny or the engine. I do hit the occassional very high rpm, but that is what the engine is built for. To perform at very high revs. I probably hit lift a lot less than most of the other XRS/GT-S owners. My concern is that I have hit lift quite a few times before 2000 KM so I was wondering if I have been hitting high revs prematurely and if it is the case then does it affect the performance or the overall refinement of the car. As a matter of fact, a Toyota Mechanic at the my dealership told me to use full rev range occasionally to break in properly, but I have seeing other XRS owners who baby the XRS a lot till 2000 KM or so. Nevertheless, your point is good that I should get the oil changed soon. Does synthetic oil help in a high performance engine?? and is it ok to use synthetic oil ( I put mobil 1 synthetic in my previous Corolla S) at around 2000 - 2500 KM????

Something to take into consideration is that there is a short time period where the cylinders are still rough enough to help seat the rings. If you waste that precious time then the walls will get smooth and the rings will never seal properly. Result is excessive blowby, lost power, etc.
I'm glad this guy can explain it better than I can:
