If you aren't light checking your piston rings, not only are you leaving power on the table, the engine might never even work right! Light checking is just one of the many automotive machine services we offer and is something that we do on every Flat 6 Innovations and Aircooled Technology engine. The difference is in the details.

Not all oils and fuel additives are created equal. We stand behind Driven's DT, DI, and Defender products as we helped with their development and know 100% they are what our Porsche and other high performance engines need. Don't understand why? For over 20 years, LN has been trusted as an expert in lubrication.

If you don't own a profilometer or precision measurement devices, how do you know a cylinder has been honed properly? Even those with proper gaging don't know what they are looking at! We regularly field calls from individuals and shops alike that have had fresh rebuilds fail. When checked, we often find Nikasil cylinders that were incorrectly honed. That's why Porsche experts trust us for both new cylinders and reconditioning of blocks and original cylinders. That's value added service where it counts.

There aren't many people who take apart a perfect good engine to figure out what makes them tick. This engine became what was to be known as Cayman X, with the first 4.2 liter MA1 engine. What's important about this picture is that you can see the healthy, stock Alusil cylinder bore, shown here with about 15,000 miles and dozens of hours of track use.

Of note is with Alusil and similar Al-Si cylinders, there is no visible cross-hatch. It's only under a microscope that you can see the exposed silicon particles that support the oil film that allows the pistons and rings to function properly.

We recently had a customer want to block off his air injection but didn't like the way people just put in a brass plug, leaving a blind hole in the port. We decided to make up some aluminum ones that could then be blended into the port. Simple but clean solution.
