Something as simple as improper surface texture can cause an otherwise awesome engine build fail in spectacular fashion.

Here, Lake Speed, Jr. and Mark Malburg dive into what caused $1B in recalls for GM.

We usually check cylinder wall finish numbers before and after honing.

What if we checked after assembling the engine, and again after breaking it in?

Sitting idly in a corner for two decades can't be good for an engine, right?

Well, after not rotating in 20 years, these dyno results might — no, WILL — surprise you.

Total Seal has brought advanced metrology to the masses once again, with this insane cylinder wall surface measurement tool.

This kit will allow an average user to measure like they are in a professional lab.

Modern piston rings require modern honing processes in order to take full advantage of their technology.

Here, Greg Anderson and Lake Speed, Jr go through the what and why of modern honing.

We wanted to see what a ball hone was actually capable of doing to a cylinder wall that was in need of honing.

We availed ourselves of a profilometer and tested before and after, as well as the OEM cylinder finish

A profilometer can really elevate your honing game, giving you the ability to actually measure your surface finish.

If you aren't measuring your cylinder finish, you're just guessing.
