A sewer smell coming from your sink could be caused by a dried-out P-trap, a clog in the drain, or a problem with the sewer vent.
Pour water in it. It could be the "p" trap has dryed up allowing sewer gases to come out.
I have seen this where water has leaked into the ductwork and stagnated.
One of the biggest culprits I have found for sewer gas smell is the floor drain many floor drains are seldom if ever used and if unused long enough the water in the trap will evaporate allowing sewer gas to enter the dwelling. this also applies to any trap which is not used regularly.
Your septic system could be backed up and that is why you are smelling a foul smell. The best thing to do is to call a septic system business and have them come out and take a look at your septic system, if you think that is what is causing the foul smell.
The smell is not dangerous - however, if there is still a smell, there could still be urine, which could cause diseases and infections if you come in contact with it.
A sewer.
No, the sewer gases could come out and fill the attic and the rest of the house.
Fleas may come out of the sewer seeking warmth, food, and shelter. Sewers provide a dark and damp environment that is conducive to flea survival and reproduction.

could be a gasket that has finally gaveway and the smell of oil is the oil burning on the engine.
Only if the trap fell off and it was not properly vented
