You can also get blue smoke from bad valve seals and guides. Also from a bad pvc valve. Older transmissions that use a vacuum modulator. When the modulator goes bad. It can suck up transmission fluid. Causing smoke. Older GM's were great for this.

Thank you for explaining this, I am going to have a compression test done anyways just to be safe and make sure the rings aren't ******. Appreciate all of the input guys!

Everything's fine, just a bit of oil slipped in from when the plugs were swimming. It's all burned out of the system now and has been great! Thanks for everyone's help!
