Puff of Blue Options

[BC_Celi10]

Any diagnosis or advice would be greatly appreciated

So, i've noticed in the last 4 months or so that when I start my 94 ST, the car will puff out blue/white exhaust I would say once a week. It occurs randomly and I thought it might be because I had let it sit for a 2 days but like I said its random. No idea if its a big deal or not. This only happens once in a while on start-up and not while I am driving.

Thanks
