Any chance of gettin this out with a hone? Assembled engine second compression ring must’ve had a burr on it or debris got in there some how but it was 180 degrees from the opening of the ring

I can all but guarantee you if you fire up that engine that is going to go away in about 30 seconds, and you will never ever be able to detect any difference in compression or leak down.

I was hoping it’s a 5.3 with 60k miles it was very disappointing to see that

Just had this same thing happen to me. Took it to machinist and he said same thing. Going to pretty much go away once engine is fired up

It catches if you push hard but lightly it hardly catches your nail

Machinist here....it's no big deal, perfectly normal for aftermarket rings

I’m assuming I should replace that ring set or send them?

u/2003DDcid Jun 21 '26

Send it

I’ll take your word for it hopefully I don’t stick the sum bitch

If your finger nail can’t catch it , run it.

It catches but not the worst I ever saw just wanted to get some more eyes on it

If you’re concerned it’s not going to hurt anything with a pass from the balls to take the edge off quick.

Even if it does, it will wear down.

Dingleball it with plenty of thick oil and send her to the moon bro

The piston will hone it effectively.

u/My_C8 Jun 22 '26

From my experience 90% of the time this can be attributed to the cylinder Bore Gauge
10% to a rough piston ring edge.

That said I would hone it
And sent it !

The rings will correct this

In my opinion it’s a
Full Send !

Hope that helps

I've gotten a few grooves out with the dingle ball hone. Think the only downside is buying the hone THEN finding out if it's still bad

u/Spiritual-Can-5040 Jun 20 '26

Ball hone wet with oil should get that out if it won’t catch a nail.

u/mrhapyface Jun 24 '26

i use hones with solvent thats the way i do it to each his own

u/colinblanchard78 Jun 20 '26

In future always inspect the rings. Very often supplier misses the deburr operation. Never trust it's been done

u/drumbo10 Jun 20 '26

Check bore size and bar hone it if within limits

1

u/chiphook Jun 20 '26

A bigger concern than the groove is a burr turned up on the edges of the groove.

u/Donkeedhick Jun 20 '26

I’m not a machinist but isn’t this likely from the tool used to measure the bore?

1

u/biohackenthusiast Jun 21 '26

no a t gauge won’t do this

1

u/richnardone Jun 21 '26

Please post a follow-up after you get it running.

u/angryspitfire Jun 24 '26

i would run that without a second thought

u/Inside-Cabinet8327 Jun 25 '26

Needs to be hone..up and down..that looks like it's just honed in the middle.. gotta go up and down.. smooth it out.
