Porsche Motorsports AOS Install in 986S

I’ve installed a Porsche Motorsports Air Oil Separator in my track-dedicated 986S. For reference, the car is a 2004 Boxster S Anniversary Edition. On other posts, you can read about the symptoms I experienced on the track warranting this change. Note number one: The TSB (also can be found in other posts) calls for the removal of the air intake distributors. I did my install without removing them. You will have to decide whether to remove or not depending on your situation. There are two a

Should be merged with this. http://www.renntech.org/forums/index.php?s...mp;#entry112455

When I checked this out with the parts guy all that was in stock was Kluber Syntheso Glep. $28.11 for the tube.


Made in Spain. So I tasted it. Tasted like chicken - I mean like silicon grease that you can buy anywhere.

I was at Marvin's shop today and he had just replaced the oil separator on a 996.

As a 986 owner I never paid much attention to this part on a 996. Thought they were the same. Nope.

What caught my attention to the 996 separator is I saw what looked like dried up coolant on it, and the 2 extra ports.

For some reason coolant is run through a 996 separator. And I guess that is why when you use the Motorsports version on a 986 the TSB says: " The two connections on the oil separator have no function in Boxster vehices and can remain open."

About that expensive Kluber lube.

The coolant connections on the 996 AOS are to prevent icing up of the device in cold weather. The engine compartment of the Boxster runs hotter and thus the coolant does not get routed through the AOS on the Boxster and Cayman. I leave these open when doing 996 engine transplants.
