It wouldn't surprise me...it's got a nine quart capacity.

 

Not true

He isn't. All engine are "cold run" at the factory before leaving, meaning that they roll them over, but no fuel or spark. The only engines that are ran i believe, are the LS7's, and possibly the LS9's Anyways, an engine's rings will not properly seat until the engine is ran under a load, causing the rings to fully expand and seat/wear-in with the cylinder wall. This is accomplished with some...i said....some spirited driving, but that is accomplished with the normal acceleration followed by the break-in procedure, and the occasional full throttle blip we all know will occur.

 

wrong answer. Please tell me your source of this rhetoric?

 

In the new GM hardcover book about the development of the 2010 Camaro ("A Legend is Born"), it is stated that the cars are run on rollers up to 5000 RPM right off the assembly line. As part of the same process, the cars are driven over a simulated bumpy road to check for squeaks and rattles, and then blasted with high-pressure water to check for leaks.
It seems that GM violates their own break-in guidelines when the cars are as green as can be.
My plan is to drive the car for about 200 miles, then change the oil and let it eat.

 

good plan. change early. change again at 1000 or 2000 miles...I have not been gentle on my car during break in. Runs great...

 

don't worry, you'll have a hundred other minor and major problems to fix other than your piston rings and bearings over the next 175,000 miles.

 

how are you so sure?

rings to fully expand? you make this up on your own? the ring is fully expanded when it is in the box!

stop picking fights... internet commando.

 

Since i have obviously struck a nerve, and you feel the need to be an internet toughguy yourself, here are a few instances to back up my experience working as both an engine builder, and a dyno test technician for your U.S. Army that sees these things every day. I could produce government studies and paperwork to bury you with data, but most of the same data is readily available online, so here ya go....Internet Commando returning fire. I'm Not trying to pick fights, just trying to inform theose who believe everything they read online. An engine needs some "spirited" driving during initial break-in to properly seat the rings. And yes, all rings are under tension when installed, but not proper tension/wear-in to properly mate with the cylinder wall for a tight seal long-term. Feel free to contact any engine builder worth his salt, and they will agree that to baby an engine during break-in isn't the best idea, but then again, don't beat the hell out of it. Try contacing Pat Musi, Nelson Racing, or any other well known builders, hell even a GM engineer or two, we have several former auto industry engineers working for us in my building that worked in various design and testing departments.


Just a few examples below for your reading pleasure.

Aerospace/Plane related, but still relative, many of the race engines we built were still broken in using mineral oil due to it's lower lubricity to allow parts to wear-in or properly seat.
