Oil Burning

Have any of you ever experienced start-up oil burning. My wifes Thunderbird 2002 10,000 mi gives the occasional puff of blue at startup

wow....NO for me, not at all. I know black means running too rich

I thought Blue meant bad rings.

Are you using premium fuel?

How often do you start it?

Is it ever driven on the highway, or just short trips?

A blue puff on start-up only used to mean oil was seeping down the valve guides overnight, collecting in the combustion chamber and burned off as soon as it was started. I don't know if that’s a possibility on the 3.9 engine.

I am not having that problem.

Have never noticed anything on bird, but than haven't paid
any attention.

On my Avalanche, this has been a big problem. GM refuses
to acknowledge except something buried in the TSB's.

They are really Horses*** about it. On the AV forum for most
the problem is coming from the PVC valve. Hole is too big
and where it is positioned sucks in too much oil. The TSB
recommend first doing an oil comsumption test. If they
feel consuming over a quart, between changes, they will
go further. Or as many have done is spend $5 out of pocket
and replace with a new PVC valve which has a hole the size of a
pin head, again which is buried in the TSB.

This has helped mine for a year, but starting to come back
so it must be full of oil now. So might check the PVC valve.
