Is this Cylinder Wall Scoring an Issue? Opinions Please

[VT_4G63]

Hello Everyone,

I am in the midst of refreshing my short block and building my head with the engine out of my Spyder GST. I am starting to get toward the end of the process.

I just found these scratches on the wall of cylinder #4. I am looking for opinions as to whether these are an issue or not. I realize they are not ideal no matter how you look at it.

The worst of the few pictured doesn't "catch" a fingernail, but I can feel it a little when I pass my nail over it. Also, I can "hear" it too.

I have added a video where you can "hear" my fingernail passing over the worst of the scratches.

I would like to avoid honing these cylinders if possible. I would say these scratches are probably as minor as they could be while still causing me to question them.

Opinions please, am I worrying about nothing or is this a major no-go?

Thank you

Rings get deburred on the ends??? But yeah, as stated, keep on going, you should be OK.

Thanks for the replies/opinions. That’s the direction I was leaning, too.

I haven’t ever removed the pistons/altered the rings since I purchased the car and there has definitely been nothing else to suggest anyone else has since it left the factory in 95/96.

I’m thinking this happened as a side effect of me cleaning the tops of the pistons/cleaning the deck/replacing the freeze plugs and blowing out the block. Some debris must have gotten in the cylinder and scored the cylinder walls when I turned the motor over. I tried to keep that from happening, but I’ve had the motor open longer than I initially intended due to my life’s other obligations.

Thank you guys for the opinions I asked for. I’m going to keep going with this build.

I've seen cars run 9's on much worse

Hone scratches are still very strong.
On paper, any vertical scoring would cause an issue, but for that minor SEND IT

While not optimal that will run without major issues.

The biggest issue I see in 4g blocks is warping of the deck surface. Make sure to check the flatness.

Yup. Once you get a proper deck surface, the headgasket leaks disappear for moderate power level builds.
