Can i vacuum out oil from spark plug wells with wet dry shop vac on a 1999 pontiac sunfire?

On the face of it, this sounds like a pretty good idea. But I'm not so sure it really is. You might end up sucking oil out of the cylinders, leaving them dry at the next start-up. Granted, the oil in the cylinders would be replaced quickly, but it just sounds risky to me. It's one of those ideas that just sounds wrong, but you're not sure why.
I guess I'd just try to poke a rag down there and sop it up.

Answer

Yes. Just leave the plugs in. Although you would find it easier to just manually suck it up a clear narrow bore tube, making sure you don't swallow any.
