Thanks for that, pretty much the same as Machinemart, I think I may be opening a can of worms when the time comes, not because the engine is shot, far from it, but as with anything that's been in there 17 years once disturbed there'll probably be a whole load of bits and pieces that will need or pay me to replace while it's out.
I was going to fit a Shark Vent to cure the problem of embarassing puffs of smoke when you come back on the throttle from the over run but whilst that may or may not cure the symptom I'm told I'm best off to eradicate the cause. A letter to a PO from Porsche informed him that 1.5 litres of oil per 1000km was within tolerance but that sounds excessive to me.
Does anybody know if the excess fumes from the crankcase are pushed back just through one bank of cylinders or both?
