Last time I was in my engine bay my AOS had a film of oil on it so it may be on its way out. Do any feel the motorsports version is worth the additional cost?
I had an oil leak after a track day and thought (or hoped) it was the AOS.....but then the drip moved into the centre....gulp....track weekend over
I had partially dislodged a new 997 RMS. Could undue crankcase pressure via the AOS be part of the problem?
