View Full Version : Smoke at startup?

10-09-06, 10:44 AM
My DTS has about 60k miles on it. Ever since I got it (about 46k) I've noticed that I get a puff of blue smoke (oil) at startup, but only when the car sits for a long period of time (more than a few days). Does the Northstar have traditional 'valve guide seals'? What else could be causing this (I have no intention of fixing it, but I am curious as to the cause).

MIne does the same thing, 2000 N* 90K
it started a few thousand miles ago, or maybe that is when I noticed it, because it has been burning 1 quart about 1 thousand miles..
go figure..

Sure does sounds like valve guide seals to me.

You would think so, wouldn't you.

Hard to get valve guide dialogue going around here. Not sure why??
