If in fact your external oil cooler seals have shredded (which they will)... you may get some choclate milk in your WATER.

I found that all the major Porsche shops forgot about this... and the dealer couldnt even find the part in his computer... but after insisting the part exists... he found it. cost for 2 seals was less than $5.... and they are the diameter of your thumb

1) Drain water
2) Pull Oil cooler cover. (oil cooler is mounted inside a cover... because the oil cooler is surrounded by engine coolant).
3) Pull of oil cooler. There will also be a spring loaded valve (looks like a thin pencil and a spring on the end of it). There is an update for this part and since you have it out, go ahead and get a new valve). I dont know what it does, but there is definitely an update.
4) 2 small rings (mine were orange) will be mounted to the fittings on the engine. You cannot see them, just have to feel for them.

Note... most of this work you can only feel... i did this all from under the car and my arm was up along side the engine.

5) slip on new rings and (dont forget the spring valve).
6) push on oil cooler and mount the cover.

7) FLUSH the WATER system. A mechanic told me (and it works) to use WISK laundry detergent. For some reason, WISK works very well at breaking down oil... Seal everything up, put water back in (not coolant) and add Wisk. Run car for a couple minutes and drain (using lower hose from radiator).

8) repeat step 7 a couple of times until not sudsy and not oily.

you shouldnt worry that water got into your oil, because the oil is much higher pressure than the water system... and we know physics...
