New Engine Being Installed

[FormerTaco]

Went in a few weeks ago for my scope test, I "passed" the official test. I had been going in for the last 6 months or so though, for oil consumption monitoring. My engine was burning oil, so every 1k miles I would go to my dealership, or if traveling, to a local dealership and have them log my oil level, mileage, and top up oil. My dealership service center saw the issues and were awesome, they pushed GM to replace my engine due to oil consumption issues, approved. I was told it may take 2 months to get engine delivered, it arrived 2 weeks later, and a few days after that I dropped my truck off. They gave me a loaner, and the day after I dropped it off they already have it on the lift. Fingers crossed. Anyone have any advice on what is needed to break in these new engines?

Break in = <1000
Wear in = <15000

Break in happens quickly and is mostly over after your first tank of fuel. You only get one chance to get the rings to seat with the cylinder walls. They have a special coating on them intended for break in. Once the coating is gone, you lose the effectiveness This will be more true with 0W40 oil. This may be partly why your motor used oil.

I would run the motor in a spirited fashion (don't lug it or redline it) preferably on an open road and limit idling time. Run it through the gears in auto and manual. Get the rpms up and then back down and vary the throttle inputs. Run it 30-50 miles and let it cool down and repeat a couple more times.. Then you can drive it "normally" for a few weeks. Change the oil early, no more than 1000-1500 miles cause it's filthy. Then do it again at 3000-3500 miles. Now your into wear in and run intervals you like based upon driving habits and conditions.

That's how I did mine. I still get a little consumption, but I use the paddles often and get into higher rpms, so there's bound to be some blow by. I change oil at 3333 miles, so its not down much and I don't worry about it.

After you get past 3k miles you can do oil analysis if you want to see how it progresses.

Good they acted quickly.
Especially as I hear of backorder stories...
