When I broke mine in I let it come up to temp then hit it a couple times with full boost. The engine turned 100 miles while on the dyno.
New Engine....scored cylinder walls, need diagnosis help

Sorry to hear this Jason. I am not a fan of SS rings because they are so hard to get seated correctly. As stated, you have an extremely narrow window to have them seat and if you don't get it right the will never seat.

Yea I almost wish I had just bought the 326 stroker from Brenspeed or the 5.0 stroker from Ford. There are so many people that have gotten them to work though. Sucks that it had to happen to me. I thought I was doing myself a favor by not skimping out on anything.....wroonggg!

What other type of rings are there that are more forgiving when seating?
What are the advantages of running SS rings?
I went through this with my first built motor, I had to pull it out after a few months and get it totally rebuilt. sigh
I just went through this... I also had wished I would have bought a Ford Racing crate motor...would have been 100 times cheaper when all was said and done.

when you say totally rebuilt you mean new everything or just got resized pistons and rebalanced with a rebore?
It was my understanding that SS rings were best at holding boost when pushing past about 14 psi??

I drove the motor for 10K miles before I gave up and decided I had to pull it.
So I had to totally rebuild the shortblock; rings, new pistons, full bearing set, balance, rework the block (the cylinder walls), etc. My cylinder walls were like glass...polished to a mirror finish.

Yea at this point, I think I'm just going to drive it on low boost and enjoy it while I can. I'll keep an eye on everything and I'll probably send the oil that is in there now off to blackstone and see what they say.
I'm a big fan of Sealed Power Hellfire rings.
Im not a fan of steel for a street car. I'm using moly.

Just a warning, since I drove my motor for 10K miles, I had more damage to the cylinder walls than if I would have pulled the motor asap.
The pistons were totally scored (the skirts)... The longer you run the motor the more you polish the walls. At least that was my case.

Livernois motor i bought never sealed, had similar issues you are talking about. You should fix it now and don't wait like i did. I was in denial about it being a big problem. ended up destroying the pistons. its not good to have oil in the combustion chamber, lowers your octane. My tune was good, rich even, and i busted a ring land eventually.

Did livernois cover the engine? If oil is in fact in the combustion chamber, I'd see that on the plugs no? They all looked pretty good when pulled for leak down on Saturday.
Today engine was almost up to temp before driving and puffed till I drove about 3 miles, not bad though.

Unfortunately that's a common thought. Sometimes the cheaper parts are better suited for the application. I don't think that most realize what's involved with having a race car motor in their street car. It sounds cool and costs a lot but isn't usually the right choice imo.
At least you are smart enough to learn from your experiences.

No, my motor was rebuilt by a idiot, and I was a bigger idiot by trusting the idiot! Oil will burn off the plugs, my leak down test passed with flying colors just a few weeks prior to my ring lands imploding.
My motor always had a ton of blow by
Would lose 1 Quart of oil in less than 1000 miles
After just 2k miles my oil looked like complete shit, black and the viscosity was broken down
New motor has none of these issues and with 3k miles between oil changes the oil still looks great! SS Modmax rings, broken in hard and fast.

You built your most recent motor right?
Bruce I understand what you are saying, but as far as my motor is concerned I was after building a real stout motor that could hold power, not necessarily a race motor per say. So I guess I'm not sure what I did to not be the best choice. I don't see what having SS rings would hurt. I guess in my case it was just a combination of things that caused it to fail, not necessarily the parts fault.

Yes, most recent (2 years ago) motor i assembled. I have all the specs for the motor to the machine shop, had them file fit the rings and bore the cylinders to match the pistons and do a 10k rpm balance. I just put it all together like a puzzle.

Whenever someone has trouble with break in or ring sealing it involves ss rings. What I wonder is why ss unless you are running a huge amount of boost? If you are running a huge amount of boost then you should probably oring the block, go with studs, race bearings, and plan to do a tear down every so often.
If you aren't going after a huge amount of boost then there isn't a reason for all the other parts imo. Don't need ss rings, don't need studs or oring, don't need race bearings, and don't need to do routine tear downs.
I think about this stuff differently than most do. I realize my thoughts aren't what all the experts advise. All too often it's made too complicated by well meaning people who think you are building a sbc that needs a whole bunch of crap because it's made with substandard parts and engineering from the get go. A mod motor uses some fairly good, high quality parts imo. They are designed and manufactured well.
Whenever you see a story of bad luck with motors it's usually the rods in a stock block or a high dollar, brand name, "race motor" that the owner buys or has built with the best of intentions.

What do you consider high boost? When I spoke with Diamond abouty goals they suggested the AP SS ring. Which I haven't had a problem with. But I didn't break them in easy.

Me? I go by what has worked for people. I've seen motors up to 25psi without ss rings do just fine.
I'm not Diamond. Just a guy on a forum. And I didn't say that everyone will have an issue with ss. What I'm getting at is if there is a break in problem it always involves ss rings.

I didn't mean for that to sound like an attack. I was genuinely curious what you consider high boost.
Funny enough 25psi is what I told Diamond the engine will eventually see.
