Porsche 912 targa 1969

[pud]

Hi , hoping for some help , when I start, the car I have blue smoke out the exhaust, it will stop after a small amount of time . It drives well , and the smoke stops when driving along , when I stop at junction and pull away I have smoke again , or when stopping at traffic lights , I am hoping it's just the stem valve seals , any input would be great , cheers ,

Check for any gasket leaks and oil seals as well.

Perhaps worn valve guides or missing / hardened valve stem seals
Perhaps running too rich.
