Oh, I forgot another test of endurance these seals prevailed through. In 2008 just before the winter when I got my new engine with the seals. The turbo oil seals let loose and all the oil drained out of the motor. I ignored the OEM oil pressure gauge and kept driving. 10 minutes later the car started losing power (I was driving on the highway) and I noticed it was blowing a ton of smoke out the back. Pulled over and long story short most of the engine was toast. Rotors, bearings, side seals, endplates etc. were all junk on a 2,000 km rebuild.
But surprisingly the rotor housings and seals were perfectly fine! This was great news for me since the rotor housing were brand new with 2,000 km on them and same with the seals which are mucho money.
Here's some pics of the destruction if you care to look...
