Borescope + cylinder pics

Was curious what 175k miles with oil changes every 5k would look like inside the cylinder.

I was kind of surprised and nervous when I saw some of the vertical marks, but they do not appear to interrupt the crosshatching.

I only looked in cylinder 1 and 2 on the driver side and these pics definitely showcase the problem areas, the rest show good crosshatching.

Not an expert, but I'm guessing some level of vertical marking is inevitable after 175k miles, no?

That’s what my mechanic said when I showed him. He was impressed with the amount of cross hatch.

I don’t burn oil, no puffs at startup, and this LC has had 5k oil changes its whole life.

I couldn’t find any other posts like this, so wanted to share should anyone else get curious and shove a camera down in there

Wonder if 5W30 would have prevented that.

Been running 5w30 for the last 25k miles or so

Great post and pics! Did your mechanic say what he thinks about how much life is left in the engine even as a guess? Looks very clean for that mileage.

The other day I was checking out a used LC at loca dealership, and the sales man said about how great the engine is and how they go to 200k miles. I was surprised he was not saying 500k .

No crystal ball predictions. Told me to stay the course / keep doing what I’m doing and not even worry about it. I’m gonna try that approach

These marks align with the piston skirt, so if I took pics of the other parts, I think everyone would be super impressed about the clear and defined cross hatch even close to 200k miles

"problem areas"? I'm not a pro mechanic, but I've had a few engines apart. IMHO those are beautiful looking cylinder walls for that mileage. No scoring, just some light marks from millions of ups and downs. That thing will run forever, so to speak. Nice post and great pics.

Makes me feel better. Thank you!!

My smooth brain understands swirly marks are good , and straight marks are bad.

Definitely validates my 5k oil change interval. Thanks for sharing.

nice pics! Any enterprising fella out there with a borescope, high mileage, and 10k OCI's?

I feel so too. I’ve only owned this from 130k miles. So just 45k miles, but one of the main reasons, besides zero rust, was documented 5k mile oil changes.
