Hi Chuck!!
Just run the AOS. I sat on the original rules committee that put BoxsterSpec together. I have traveled the country running the 2.5 cars since Nov. of 2005. I have replaced a total of 2 AOS at track events since then.
The 2.5 car's have close to NO issues. A forum member here "Topless" has his OE 1997-98 horizontal AOS still in his car!! The very first versions had a horizontal diaphragm, the newer versions have a vertical diaphragm. Topless hits at least 10-12 events a year and is by no means what we deem "a back marker"
The real issue with our AOS? (on 3.2 and up engines) they cannot drain the oil back into the engine fast enough as they fill up. This is why it gets through the diaphragm. Porsche solved the issue several years back on the 996 3.6 engine, then a newer fix for the CaymanS engines.
Are you the new owner of Goodies?
