Default Re: Break in secrets

The Bonami powder is not a myth. I've also heard the stories from old time mechanics abput using it to seat the rings in large diesel engines in the past.
They would use about a teaspoon's measure dusted into the intake with the engine running.
Also, even today, there are Aircraft engine rebuilding companies in the midwest that pre-seat the rings in engines by mounting the piston and cylinder on a special machine that cycles the piston in the chromed bore with a fine lapping compound, on the bench.
Google it like he said.
