Blue Smoke on Start Up

Just wondering what the prognosis may be with blue smoke on start up on my 1.9 DG Water Cooled Wasser?
Is it time to proceed with the EJ25 Subaru I have in the workshop?
Thanks

Blue smoke is not normally good, but only on start up? (ie, not on accelerating or on the over-run?)
Two easy things to do = get a compression test done and check your brake fluid level
(yes, brake fluid can leak from the servo diaphragm, into the servo vac pipe and thence into the inlet manifold - admittedly less likely, especially on a T25 where the servo pipe is very long, but worth a check)

Thanks m8
It is only on start up for a second and then nothing - even under hard acceleration.

OK, bit odd, and if as you say, no need to worry at this time I don't think.
The only time i have come across that symptom is when oil has pooled in the head (when the engine has been sat for a while) and is sucked down the valve guides on start up. Not a common thing to happen to a WBX though, not in my experience anyway.
Anyone else got any thoughts?
