rev the engine to 5000 rpm before break in period

Please tell us where you get this wrong information. Engines are assembled and installed. The only "testing" they get is as the finished car is moved around under its own power: out the door, to a storage yard, on a transporter, on a ship, in another storage yard or two on a transporter, and around the dealers lot. 20 miles tops.

Not sure if this applies to all engines built.. When I bought my last corvette, I did the museum delivery, flew out to the factory and picked up my car directly from the factory. ALL engines produced are fired up and tested using natural gas. This way they can be shipped without gasoline in them. (Engines made at different plant).
They are run to redline along with some other tests after assembly before being married to the chassis. I'm sure other OEMs use similar practices.

Our engines are also run up on natural gas, it's not a break-in procedure for the entire powertrain, it's just a quick test to QA function.

Car is totaled. I'll give you $1200 and haul it off for you.




J/K, I hit the redline on the test drive in mine. You'll be fine.

Seems strange to me that in America there is a 1000 mile break in necessary and in Europe we can go full throttle from day 1.

It is because America is home of the the lawyers. Lawyers in the company I work for have their hand in everything.

I know for a fact that the engine in an Audi R8 is "tested" at very high rpms prior to insertion into the car. I find it difficult to believe that a company like Toyota doesn't test their motors for QA before it goes out the door. I stand corrected if I am incorrect.

I was told its like this in America because when they ship them overseas, they put a grease/oil on the exhaust that will burn off in higher RPMs emitting a smell. Nothing to worry about, but after 1000 miles the grease/oil should have disappeared and be fine to

I checked the manual (it is the dutch version) in detail today and the break in periode is also mentioned in t he European manual. For the first 1600 km we are not allowed to go above 4000 rpm unless it is an emergency.
I think i had e few emergencies yesterday.

Its mentioned in a part of a the manual where i wouldn't search for it.
Drive procedures/ driving away on a slope.

And on monday i gonna pay my dealer a visit and ask him where he got his information about het break in period..
So it is not an American thing to cover themselfs for any lawsuits.

lol im gunna guess its about 50% of people dont go by the break in period at all and drive there car hard from the lot. its not gunna do anything, i took a silver limited on 3 test drives, redlining it everytime and it had under 50km on it, if the break in period mattered at all, the guy that bought that one would know!

[wbradley]

I drifted my 86 in a wet parking lot the day I got it.

The only way to reset the break in is to bounce the tach needle off the redline a few times.

Well. Good for you... But that proves nothing.. There is also more to a car than its engine. Gears need to be broken in and form a proper wear pattern, brakes need to seat as well.. Just because nothing broke as of yet.. Doesn't mean that tolerances and wear patterns aren't affected by extreme use. These things sometimes show up as too much slack or unexplainable clunks and clangs some miles down the road.. While nothing might not have come apart.. That doesn't mean that all is as it should be and problems might arise at a later time..
It's just common sense to allow thing to seat and get lots of heat cycles before you explore the limits.
Those who ever had an engine rebuilt know to follow a proper breakin procedure for long life... Well.. That goes for a new engine too.. And brakes and gears..
Just about every OEM has a breakin procedure documented.. Seems the OEM engineers might know a thing or two about their products...

[Braces]

If Owners were planning to keep their cars forever .... Maybe they would be more inclined to follow the break-in schedule. How many people actually own their cars for longer than 4-5 years?

Manual? What da hail is that?
