Default How to get rings to re-seat?

Iv been driving my ol buick for a while now, and its got alot of blow-by. The motor only has bout 50k on it, so i highly doubt that the bore is worn that much. The motor sat for a long long time as well, so im thinkin that the rings might be eithor stuck, or not seating.

Any tricks to make old rings seat again?

its a 320 inline 8.

You can try a little Marvel Mystery oil in the crankcase, and then give it some exercise to see if they'll un-stick themselves. If they're not seating the cheap-o way is a teaspoon of Bon-Ami down the carb while the engine is running.

Marvel Mystery Oil, or ATF, down each spark plug hole, let sit overnight, push outside before starting, start, after huge smoke cloud covers neighborhood, pull out before neighbors can identify the source of the smoke and head for the highway, a nice 40-50 mile trip at varying speeds should fix you right up. It did the flat six in my old 48 Plymouth Woodie Wagon that had been sitting for about 20 years.

Yeah, don't put the Marvel Mystery oil in the crankcase, that won't help your situation and will just thin out the oil. In the spark plug holes is the ticket.
I once has a Porsche that wouldn't seat the rings after a rebuild so as a last ditch effort before pulling it back down, we poured Ajax down each barrel of the Weber's and damn if it didn't work! Don't know if it would help for stuck rings though, probably not.

I once got an (ACK!) Pinto for free that had a stuck motor. I really needed a beater. I poured a liberal amount of liquid wrench in each plug hole, then, the next day, I dragged it around the block in gear for a while, popping the clutch occasionally and it freed-up. I then changed the oil to 10W30, put in the plugs and battery, and it fired up!. I got it hot, and it smoked like hell. I changed the oil to 70W Valvoline nitro oil and drove it for 18 months, 'til the body broke from rust. Try that on a modern car.

My Grandfather was a Ford mechanic for 34 years, and also worked on friends and neighbors cars on the weekends.

His old trick was to pull the plugs and saturate the rings with Liquid Wrench and let sit overnight.

He'd change the plugs and oil the next day and fire it up outside. The smoke cloud looked like one of those old mosquito spray trucks was in the driveway, but after it warmed up and ran for an hour, those rings would pop out and the compression would come back like it was new.

Great minds think alike!

Liquid wrench, MMO, and or kerosene in each cylinder. Let it soak overnight, and then give it an italian tune-up... Should do the trick.

Repeat if nessecary.

Over the years we've had customers buy the small bottle of GM posi-track additive (#1052358) to add to their motor oil to help free up sticky lifters and piston rings. It's a detergent additive designed to clean the varnish and glaze off the posi clutch plates that makes the diff pop and chatter when making turns at low speeds. Seems to perform a similar function in the crankcase, at least some of the time.

I second the Bon-ami. I heard that back in about 56 chevy had a prob with the rings not seating on the new cars, they brought them back in and gave them the Bon-ami treatment. Poured it down the carb with the motor running.

Although Bon Ami has been known to work, before resorting to that I'd try some G.M. Top Engine Cleaner. The old style pour can part number is 1050002; I don't have the part number for the newer style spray can in my head. I've had good luck with it as far as unsticking rings from the ring lands goes. It'll also do a good job of decarbonizing the combustion chambers and piston tops---not that a Buick straight eight would ever have such problems!

I have a 392 Hemi new build seems like the rings never seated right
how much Ajax ,would you pour down each carb ,while it was running
also will it hurt the carb

The Bon-Ami will do it as we gave an engine a pretty heavy cocktail of this,, like 2 inches in a pop bottle and fill the rest with gasoline,, Shakin Not Stirred,, and pour it down the throat. We then ripped the engine apart and there wasn't even as much as a scratch in any of the cylinders but the rings had a fresh look. We did this test just to see if it would rip up the cylinders >>>>.

MMO is great! In the spark plug holes to un-stick rings, (whether they're stuck in their grooves or to the cyl. wall), down the carb for valves, in the crank case for sticky lifters and valves. As suggested above I've used kerosene to un-stick stuck stuff too. 2 qts of kersene and 3 qts of oil at oil change time makes a pretty good wash for the inside of an envine too.

I have an OT car out back I'm going to try the BonAmi thing on. Will it work on a fuel injected 4 cyl?

A note of caution to everyone listening.

The title of this thread, "How to get rings to re-seat?" is in contrast to the question being posed by the OP, which is how to get the rings un-stuck, presumably from excess carbon or gunk buildup inside the engine.

Using bon-ami will score the cylinder walls, basically put 20,000 miles worth of wear and tear on an otherwise new or "not yet broke in" cylinder bore.

Yes, the bon-ami trick will work to seat new rings... Or even old rings in an old engine that have never seated in the first place, but it will do absolutely nothing to "un-stick" gummed up or frozen rings... Except maybe make the problem even worse!

I would advise everyone reading, or considering this to use some common sense!!!!!!

One piece of info.

Bon Ami = yes

Ajax = no

for what it's worth, the only 'approved' stuff is Bon Ami. Ajax and generics are a no-no. the bad stuff either just dont work, or can do bad things to your motor. I unfortunately do not have a good explanation for why this is so.
