At least I'm not alone having a bad turbo.. :-)

The company that sells the turbos had this as an option for about
$100. At least it is a bit better than the regular bearing. :-)

I don't know so much more, but with a chipped 20vt running close to
the K24 max boost, such a bearing will make the turbo last a lot
longer. On a non-chipped 20vt or a 10v, it doesn't matter, the
relatively low boost on those cars doesn't put that much stress on the
turbo, especially the 10v with K26..

I'm running 5W-50. The only Mobil 1 we can get here in Norway
(probably the rest of Europe too) is 5W-50 and 0W-40..
