At the time I was totally gutted and thought I'de never see Myself behind the wheel of another Porsche, but alas having since owned an Audi Quattro TT that came along at the right price I always hankered after owning another Boxster and decided to sell the TT and search for another Porsche, but this time the Boxster 3.2S.
I took my time and looked at a lot around the country and finally found one in a Basingstoke dealers that I was looking for with the right spec.
Everything seemed fine, yes there were a few things that needed doing to bring it up to my standard but apart from maintenance items all seemed very good and I was happy.
I picked it up and travelled home to Weston super mare being followed by my wife in her car, all was perfect until i got about 5 miles from home on the M5 and decided to put my foot down just to give it a blast and noticed that over certain speed plumes of smoke were exiting from the rear of the car up until then there was no smoke at all and on dropping the speed the smoke cleared.
I've run the car since and on start up there's no smoke, driving along the motorway theres no smoke, hit 90 and smoke is exiting from the back end slow down and its clear,
could this be a gasket thats failing and pushing oil onto the exhaust manifold/system, has anyone come across this before?
Any help or ideas would be much appreciated, I hope i haven't bought a lemon as i have no warranty as the mileage was over 90,000,

Regards, wilky.
More likely an AOS reaching the end of its life; you need to check two things: Your oil level (excessive oil level will sometimes cause this), and the vacuum level (in inches of water) at your oil fill cap with the engine idling.
