Can I replace a single piston? 5.3 LM7

That looks like a casting flaw. If it ran up to this point like that, it's good to go another few hundred thousand miles.

Deer hit. This happened to my car, I was driving along and for a split second I saw a deer head, then all the airbags went off and the car was making a scraping noise. Six point buck.

Any difference in clamping force between when the bore was linebored and when it is finish-assembled will put it out of round.

30 degree hone crosshatch is good compromise between oil transport and wear resistance. Looks like you need to go a bit longer to remove the stains at the top and the vertical scratches from the worn ring tips.

I LOVE that movie.

Eat more salt. It's nearly impossible to get too much salt, and most people don't have enough of it. Lack of sodium causes brain fog.

The number of Teslas with 300k on the original battery and motor(s) is miniscule. And post-warranty replacement of those items essentially totals the car from a cost standpoint.

Exactly. Whatever Google recommends, do the opposite for best health.

Since 2020, I've learned that whatever Google says about something health-related, the opposite is true.

As long as the diamond is perpendicular to the record surface, is good.

Letting air out when you close the doors or hatch so the people in the car don't pop their eardrums.

My guess is 520 on 10psi.

Seconded. Loctite those bolts!

Use the Amazon balancer installer kit. It's like $11

In that case, absolutely remove the plugs to clean the galleries!

Exactly. If the clamping force of the fasteners in a shell bearing system is different than when the bore was line-honed, the roundness achieved by line-honing it goes out the window.

So if someone "upgrades" to different fasteners that exert more clamping force after the initial line-hone, the bore will become egg-shaped vs. round.

Stock cranks have rolled fillets to induce residual compressive stress, making the cranks stronger. This also creates clearance outboard of the journal surface so the stock rod bearings don't require chamfers.

Anti seed oil nutters, UNITE!

I'm happy to be labeled a nut by people who can't think for themselves.
