On the run…

Buddy has an engine that sat around for a while, while the car was being built. Engine runs fine, just low on compression due to the rings never fully seating. I've heard their are a few tricks to help seat them even after having run the car for 200 + miles. The scariest trick that was told to me was pouring a teaspoon of Ajax into each spark plug hole, then firing it up ![](/ubbthreads/images/graemlins/eeek.gif) Anyone have any tried and true tricks of the trade, other than tearing it down ![](/ubbthreads/images/graemlins/shruggy.gif)
It really doesn't matter whether you win or lose… as long as you look good doing it!

Not Ajax.
Bon Ami, sprinkled down the carb as the engine was running.
At lease that what I used to hear when I first started working on cars, about 50+ years ago!
Never tried it and wouldn't recommend it. Run it hard or tear it down.

Run it hard
X2 and read "breakin secrets" at www.mototuneusa.com (5 minute read) & no bon ami/ajax
I read this link posted by Rapid Robert and first thought... "Easy for THEM to recommend I wail on a fresh motor... Its not THEIR engine." It began to sink in after reading similar arguements elsewhere. I posted a question.. "How long do I have to wait until I can Peel out?" Look it up. NOBODY suggested to baby it for 500 miles like it says in many old school owners manuals. It seemed abusive to me at first. I sold new cars in the 80s and since then, I had the imprint in my brain that new or rebuilt components need to be driven with care. In 2004 when I built the 440/493, I drove it REAL easy during the first 500 miles, then changed the oil. In the next 2500 miles, it used oil, got slower and eventually started smoking . I pulled the motor out to hone it and put in new rings.

buddy told me he does 4-5 burns out to seat the rings. They are either going to seat or not. I burned up the #3 on my supercharged 440 TWICE. Both time I honed the wall real quick then dropped the piston,,, just drove it. Never had any problems. ![](/ubbthreads/images/graemlins/drive.gif)

WHICH grits ? ... what brand and price?
Don't recall exact grit, they were right off the tool truck, but seemed to be on heavy grit side.
I have a MH 413(dished pistons) that I am putting some std bore(flat-top) pistons in-it. NICE bores ...all I think is that the bores need to be scuffed-up a tad.
