I had been thinking about the sea foam for a good while and I guess it might be best option at this point - don't own a leaf blower lol but that sounds interesting. However I'm getting increasingly worried about that LIM leak and really need to prioritize that as well...usually when I get home from work and turn it off, I can find a bit of orange popped up in one of the crevices along the front edge base of the s/c, and I remember in fall there was coolant pooled around injector #3 too. I'd show a pic but...photo buckets a you-know-what lately and I need to make an account elsewhere. Probably imgur.
