How many People have actually had the Valve Stem Seals Changed? I have seen 1 DYI on here, but I think it is a common job on this car? Maybe 20% of engines over 100K miles.

Here are the symptoms (I have it too)

No problem at start up.
After car has warmed up, it produces a big puff of smoke after idling for a few minutes.
(Mine just produces the smoke from the driver side exhaust only.... (Is this the common, or do people see it on both sides?))

Repairs I have done.
Lower Oil Pan gasket
Both valve covers with upper timing covers
Alternator gasket
Vacuum Pump
Crank Case Valves PCV, and new hoses
(I also tried to pour Seafoam into the crankcase PCV, did nothing)

$1000 for this repair job is a deal!!! Most shops dont even want to talk about the work around, anyone know where to get a loaner cam adjusting tool set?
