Unfortunately, generally (yes there are exceptions) when crankshaft shells wear and eventually cause a crankshaft problem (unless they have copper plating which not every one does), when 996 3.4 cylinders have stretched far enough to imminently crack or when cylinder bore material is about to escalate into a score - none of these will show signs on an oil analysis - as they usually occur in seconds from Ok to damaged.

This is why a more general understanding that these engines usually do not last as long as previous Porsche examples and that there may be a mileage when a rebuild is imminent but there are no concrete signs - is beneficial for those wanting to keep their cars long term.


Sometimes I agree that waiting to see what happens may prove a good move - I suppose unless you have adequate funds to fix one or fancy a more powerful replacement.


Other wear shown up from chains etc will be gradual and non specific in an oil sample but an IMS about to fail will if the test is just before it finally breaks up.
