oil over fill = engine gone
During an oil change on my 997.1 turbo a local shop drained the oil tank but not the crankcase then proceeded to add 8.5 quarts of oil. The car was driven to the edge of the parking lot where smoke was noticed so I idled back to the shop (probably 200 yards). The oil was drained (10.5 quarts) and the correct amount was added. Car was started and was still smoking so they called the Porsche dealership and was told that the engine was probably toast but we might be lucky and to idle car for several minutes to see if it would quit smoking. After several minutes the smoke seemed to be diminishing so I thought i would drive it around the block to see if it would clean up. As I was pulling out of the parking lot there was tons of smoke and some very bad sounding noises. The car was hauled to the dealership 120 mile away and the diagnosis was that the motor was trashed. After almost 2 weeks I just found out that the local shops insurance is covering 100% of the cost to install a brand new engine (approx. $35,000) and car will be done this week. Lesson learned dealership service only on all 3 porsches from now on.

Unfortunate story, glad it worked out. Make sure you have PCNA and your dealership document WHY the engine was replaced (is it new or "refurbished"), so that you don't take a significant hit if you ever sell your car.
On another note, are you at all handy? The oil change for a 997TT is quite easy:

Glad it worked out for you. If the crankcase was full, how did they possibly get 8.5 quarts in the tank? Does it have 2 quarts of expansion room? Worrisome too that the electronic gauge would have just shown all the bars full - gauge doesn't tell you how much it is overfilled.

My motor ran only a couple of seconds while puffing out white smoke when I over filled. I had my local shop pull the motor, change all my sensors, spark plugs, intercoolers, turbos and she runs great ever since...

oil probly overflowed into the intake side, causing excessive smoking. you could have cleaned it up before restarting. guess it was one bad move after another. glad insurance covered the job.

It was an oil change place that has done the maintenance for several porsche owners over the past few years (the closest dealership is 120 miles away). The manager is an ASE certified master mechanic I have known for 5 years. They have serviced all 3 of my porsches prior to this with no issues so I didn't pay that much attention to what was going on during this one. This was their last time on anything exotic, back to goob and lube only from now on.

The engine is a brand new in the box porsche piece.
When I take the car back to my other home where I have a lift etc. I think thats the way I'll go.

what precisely is the failure mode that requires an entirely new engine? I don't know tt engines (TPC services mine), but I know race bikes and I've blown more than one engine on the track, but its always parts that get replaced, not an entire engine.
