Engine Break-in

I used 15w-40 Rotella and BG products MOA and as soon as it started took it up to 1800 and let it run there for 25 minutes while monitoring temp & oil pressure. No cam problems. The worst thing you can do on a fresh engine is let it sit and idle, and I see people do it all the time.

I build detroit diesel engines and allison transmissions as part of my job. And even though I have been doing this a long time, I still refer to the book because somethings are too important and expensive to rely on memory alone. If I blow up an engine or trans, it's $20,000.00 and my job. So yes, I do read the instructions.
