1200 Miles...FINALLY!!

Pauly

baer, i heard similar info about engines being pre-run at the factories. where could i find information that would validate this theory? dont get me wrong, im sure you have done your homework and are more knowledgeable about this than i am, i only ask because this concerns me greatly, since im picking up a new one next week.

When people refer to "break" in,they are referring to piston rings even if they don't realize it,your rings need to seal as quick as possible to get a hold of oil control issues ,there are other reasons on why engines use oil but I'm talking about "rings" ,the rest of the engine is for the most part broken in.

As far as getting info on factories and their break in procedure you would have to just google it and you will come up with some info ,but as to where to find it I don't know off hand(I busy putting in my SC).

Oh!! and by the way my engine has a little less than 5k miles on it and I'm putting a Stage 1.5 GTM Supercharger on it so I think my motor is broke in.

GM runs LS7's on natural gas to around 2000rpm where they are dynoed, and the numbers extrapolated to ensure that each one makes 505 SAE NET. The engine is then shipped from Wixom to Bowling Green, where it is put in the Z06, and the car is driven through the factory off the line over a rumble-strip to the alignment verification machine, where the engines see on average 3800-4400rpm for a short period of time and the transmissions are run through the gears. Then the car is driven through a massive "car wash" looking setup that tests for leaks, and then onto the test-track out doors where the car is taken over all manner of un-even and rough pavement to test for rattles and squeaks. Then, to the CARE process for final inspection, then onto the trailer to your dealer.

That is the only process I am certain on. I am sure Nissan has a similar process, although I doubt they are that picky about their VQ37's to engine-dyno each one in such a manner.

Dyno an engine is not what he was asking about ,he is asking about break in procedure two different things.

Noone that I am aware of actually breaks and engine in at the factory. Maybe some of the ultra high-end cars, but I wouldn't know.
