Blue Smoke on Start Up

[crazymilk]

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?
