[s-cars] White/Grey Smoke on Startup

[Brian Powell]

Sean,

Thank you for the reply. When I do drive the S6, it is for longer
periods and the oil temps always get to at least 100C. That being
said, it will sit for a few days to a week (it is driven on the
weekends).

There was a good bit of water coming out this morning. My 90q20v
(another 20v I5) did this for a short period a few years ago, but, has
never done it since. It is driven every day, but, rarely gets up to
temperature. Poor little beater car... :)
