Just because an engine rebuild advertisement says “LN Engineering” or “Nickies” doesn’t mean the shop is affiliated with, approved or endorsed by LN Engineering. Certainly not an IMS Retrofit or IMS Solution either.

This video from Lake Speed Jr., The Motor Oil Geek, explores the science of solid lubricants, contrasting them with traditional lubricating oils, through examples ranging from Pinewood Derby cars to advanced aerospace and motorsport applications. Featuring expert insights from Dr. Peter Lee of Southwest Research Institute, the discussion centers on graphite powder, diamond-like carbon (DLC) coatings like those used by Porsche on valvetrain components, and innovative variable hardness coatings, highlighting their roles in reducing friction and wear in mechanical systems.

Everyone knows oil is a lubricant—but not every lubricant is an oil...

The goal of a proper Porsche M96/M97 rebuild is not simply to replace rings, bearings, seals, and head gaskets. The goal is to identify what failed, correct the cylinder problem, inspect the supporting systems, replace known weak points, and prepare the engine so it can be assembled, installed, broken in, and maintained successfully.

Another great podcast from Derek at Eleven After Nine—this time with Lake Speed Jr., The Motor Oil Geek.

Even after years of working with Porsche engines, I learned something new from this one, and I think most Porsche owners will too.

They dig into bore scoring, used oil analysis, engine wear, and why looking at trends over multiple oil changes can tell you far more than a single sample. Lake also explains what elevated iron, aluminum, and silicon can reveal about what is happening inside an engine.

Rich on facts. Light on opinion. Definitely worth a listen if you own, service, or simply want to better understand a Porsche.

So why do you need to replace your water pump as part of preventative maintenance? The bearing's balls actually ride on the shaft, not a hardened bearing race. That's why they fail in your M96/M97 engine and you have to replace them every 4-6 years or at most 75k miles.
