Smoking from tailpipe

Saabs that have smoke from tailpipe on startup and otherwise:

Some smoke on start up is "normal" and is from oil bypassing in the turbo. If it more than a puff on start up, the pcv system should be checked first. If breather is intact and free flowing and engine still smokes the next step is to remove valve cover and clean breather passages that are built into valve cover. labor should start at 1.3. Depending on how much sludging and build up is found it may require bench time to clean that extends beyond the initial 1.3.
