I've tried searching but been unsucessful, is there anyway to make particle smokerings?

You could create a texture with transparency, a textured ring sort of viewed from a side angle like a squashed oval to give forced perspective.

Upload that, get the uuid and use it in your particle script. Here's parameters that will make them float upwards and expand larger as they go:
CODE

[PSYS_PART_START_SCALE,< 0.1,0.1,0.0 >,
PSYS_PART_END_SCALE,<0.25,0.25,0.0>,
PSYS_PART_START_COLOR,<1.0,1.0,1.0>,
PSYS_PART_START_ALPHA,1.0,
PSYS_SRC_TEXTURE, "uuid of your texture",
PSYS_SRC_BURST_PART_COUNT,3,
PSYS_SRC_BURST_RATE,2.0,
PSYS_PART_MAX_AGE,2.0,
PSYS_SRC_PATTERN,PSYS_SRC_PATTERN_DROP,
PSYS_SRC_ACCEL,<0.0,0.0,2.5>,
PSYS_PART_FLAGS, PSYS_PART_INTERP_COLOR_MASK | PSYS_PART_INTERP_SCALE_MASK]


You'll probably have to play around with that to get it just right.

I just put this together tonight (with negative z accelleration) and a water-drop texture to make a leaky fire hydrant.
