Popping on sky star and orings


I just added and new coil for my aspire revvo sky star kit. The original coil was perfect, but now I changed it every time I start first fire up it pops loudly and shoots liquid through my mouth. I have tried cleaning it and making sure everything is perfect it still does it. The coil is registering as 0.16ohm and I have set at 70watts.

Also can someone tell me what the orings are for and how to install them?

Thanks so much!!
