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

Anyone have any tried and true tricks of the trade, other than tearing it down

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.

Bon Ami was for chrome rings back in 1960. I never tried it tho'

Modern rings either break in during the first few minutes, or they don't. It depends on the quality of the cylinder wall hone as far as I am concerned.

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.

The first thing they do on a dyno is run the engine for about 15 minutes with a slight load on it at about 2500. this gets everything up to temp, fluid leaks checked, timing set, cam break in if flat tappet.

After that its an all out assault. After that, the rings are broken in (or not if there was a problem)

was always told that if you break a motor in like a wuss it will run like a wuss....lol

i always break the cam in. make sure there are no leaks and or problems. then i drive it kinda easy to the main road which is maybe 2 miles away then its hammer down.


It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

I agree that proper cylinder wall prep is the single most important factor. By proper I mean that besides the obvious ie. perfectly round with no taper that the finish should be appropriate for the type of rings used. Most modern moly filled rings like a pretty smooth finish. Excessive oiling of the rings and/or too gentile a break in can cause glazing and excessive oil consumption. Putting the engine under a brief load in the higher gears and then letting off the gas quickly can help seat the rings. Sometimes the use of a non-detergent oil for the first 100 miles or so can help with rings that are slow to seat. Regarding compression and oil consumption, I have seen engines with good leak down and compression #s that used oil. I've also seen just the opposite, very little oil consumption, but poor test results. Good luck.

WHICH grits ? ... what brand and price?

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.

Use a real hone...if you want your rings to seat correctly.

Built many race engines for the roundy round guys. Break the glaze with a dingle berry (i like that name) hone. Start the engine, break in the cam and lifters and go racing. Everytime breakin an engine low and slow they ran that way. The only real problem is that on a fresh engine built to stock specs the bearing clearances are usually tighter and you really need a good oil for the first hour, then drain and go.

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.

Don't recall exact grit, they were right off the tool truck, but seemed to be on heavy grit side.

Nope...it comes from getting up everyday at 5:30 AM everyday for 26 years now and making sure 5-10 guys have work for the day. And then working smart all day long for a long time. That's where it come from.

I'm at work right now, wrenching on dirty greasy trucks so I don't have to pay someone else to do it, That's how I work smart to make money.

Where you at? you making at money today?
