Faust Posted December 24, 2009 Report Share Posted December 24, 2009 I have been looking at a '01 STS at a local delaership. Mileage is high, 160K, so I am wary. The only defect I have noticed is a fairly heavy oil film on the front valve cover. This is heavy enough that I had to wipe it down to read the lettering. I know oil leaks in Northstars are common, but is this any particular cause for concern? Is it an easy fix? Link to comment Share on other sites More sharing options...
