Ok, here is the issue.

The 95 850 Turbo my son's are driving has roughly 228,000 miles. The last couple of weeks I have noticed that after sitting for a couple or three days, it has started to puff out some light blue smoke at idle just after starting, and noticeably (as in a nice sized cloud) more when it is revved. This lasts for about 15-30 seconds then diminishes as the car warms up. Once it reaches operating temperature no smoke at all.

It has not used a drop of oil in the 2500 miles since the last oil change, there is no oil in the coolant, and it runs strong and smooth (turbo pulls hard and steady)

Tonight, at idle with a warm engine, I pulled the dipstick and got a steady stream of bluish smoke out of the dipstick tube. This tells me it is most likely time for some PCV system work.....Correct?? I'm also assuming that would be a likely cause of the oil smoke at startup.....Also correct??

Finally, I am due for another timing belt change in about 10,000 miles. Can I let this go until then and do it all at once, or is the smoke issue the cars way of telling me to do the job now!

Thanks for any advice.

Have you ever changed the valve guide seals?
Thats what it sounds like to me..

 

I agree with Matt. However, if you have smoke out of the PCV it's past time to do that job. Waiting may cause you more trouble and start blowing seals.

The timing belt has nothing to do with the PCV job, unless you let the clogged PCV blow your front cam seals. Then you can do the cam seals with the timing belt.

 

Valve guide seals were done about 80,000 or 90,000 miles ago by a PO. Might be time to do them again? I'm going to do the PCV system first

 

Do the PCV first and go from there.
