This has turned into the topic from he!!
Bon Ami // Ajax .. .. Maybe I can use steel wool to re-hone the block ? Just cut it up and pour the shavings into the cyl through the spark plug hole. Then crank it over for a few minutes before I re attach coil and fire her up ? ? ?
Has any one tried this ?

...I tried the AJAX yesterday and it worked perfect. The entire engine and engine bay is clean as a whistle. The trick is to use different size brushes and rags to get in around the engine mounts. Thanks for the tip

The Bon Ami Trick
Yes, higher cylinder pressures will break in compression rings faster but the oil rings have to break in on their own. As my compression rings had broken in but my oil rings didn't I had to resort to the "Bon Ami Trick" to cure my oil consumption problem.

Do you have this as a documented procedure from any maker of engines and ill even accept those made in 1815 to present . Steam or otherwise .

Oil is not the issue,
Have the engine builder explain what in the synthetic oil will prevent the rings from seating,
synthetics have a more uniform molecular structure along with fewer additives, the ability to handle temp swings to the extreme better than dino's and less volatility.
what about this will cause rings not to seat?
the only true way to find the problem is to take it apart and inspect it.
a leak down will tell you to some extent what condition the compression ring is in but will not tell you anything about the oil control ring

this is the corvette forum. we don't listen to logic and science. despite the fact that synthetic is in from the initial factory fill on many high perf. engines, we prefer to believe it is too slippery and that it will make the seals leak. oh, also it is so good it makes more HP and can go 75,000 miles between changes...as a matter of fact, synthetic oil is so good it is worth paying 5x as much as dino oil, even though all synthetic oil has at least some (if not most) of the base oil being dino...
For Paul's case it looks like it was rebuilt and ran in with synthetic oil producing a lousy piston ring to cylinder wall mating, clear as mud to me.
Hope you get it figured out and doesn't cost you.

No worries, you'll soon have another opportunity to get it right after the "bon ami" does it's job on the rest of the engine.
I wouldn't want to tell a 50 year mechanic how to do a break in on his engine though.

Once again, who here knows what oil is used for the first fire up of any engine from any manufacturer? Does anyone really think the oil in their engine in the car they just bought off the dealership is the same and only oil ever used in that engine ?

100%.. If synthetic was the only oil you need from breakin to junkyard, Why would EVERY oil maker, AMSOIL, Royal Purple and all the respected performance oil makers, recommend and sell BREAK-IN OIL for proper ring seating ?..And Every engine builder, Blue Print, Pace Performance , all the rest, recommend BREAK-In oil again, for proper ring seating?..I cannot understand why some here deny or just chose to ignore the facts..And to compare rings designed for a 2016 Fuel Injection engine to rings for a 1960 s engine is ludicrious.. in My opinion

Are the so-called "break in" oils a lighter weight non-detergent single grade? Just curious.
Also, how many of you guys have used the "ball" hones to break the glaze? I have always used my old Lisle 3-stone glaze breaker but have considered buying one of the ball styles just to try it out.

Anyway.... Did not pull the plugs today due to the "red headed bitch" as my wife calls her, ... Work on her ran overtime due to bleeding the brakes a thousand times... But that's in another thread I have running today ....
Tomorrow morning I will attack the plug issue

I try to post armed with all the facts I know 99% from personal experience. Never from second hand experience and never from what is on the internet.
I wonder if I went down to watch my 2016 Corvette getting built whether or not I would ask what type of oil they are using at first startup.
I would probably ask what type and grade of oil it uses under normal conditions. I think the question of what type and grade of break in oil would be far from my mind as other more important questions would come up first.
So do you know someone who can say for a fact what oil is used on first startup of a new Corvette ? I would like to hear what they use.

No ill intent ment just posting what is specifically from the Amsoil site;
this is from the Frequently Asked Question section,
Must new cars be broken in using petroleum oil?
Answer: No. AMSOIL synthetic motor oils can be safely used during break-in. In fact, many vehicles, including the Dodge Viper and Chevrolet Corvette, are factory-filled with synthetic oil.

New cars, yes. But new cars are different from a rebuilt engine in two ways:
1) We don't know what was done at the factory. They may have done initial break-in using a special oil.
2) Although a new car is delivered with synthetic oil, the factory may have added a break-in additive.
