"These build journal entries are part of a Special Series on the S65 VANOS covers failures, the available preventive solutions, and my unboxing & installation notes of the Snap-In Covers.

In this entry, I document my unboxing notes and the technical features of these VANOS covers."

They're light. 

This is arguably the first thing I noticed when unboxing the covers. They are CNC machined from 6061 aluminum as to not add drag to the engine. 

If you throw these outside, the wind will catch them. 

They're thin. 

This is another obvious aspect of the covers once you see them in real life. The covers as there to hold the cam bolt into the VANOS gear.

It doesn't need to be any thicker, and I don't think you can get them much thinner without drastically increasing risks of bending them during installation. 

Nothing more, nothing less. 

The tabs are obvious. 

There are 6x tabs across the cover. 

The alignment tabs have a different design.


The alignment hole. 

I'll touch on why this matters in my installation notes. 

The edges are sharp. 

You're going to get your fingers caught once as you probe the tabs yourself.
