i accidentally washed my blaster with the lid off my injector but my seat was on. do you think any water made it past the seat into the injector?

 

I assume that you mean that the lid was off of your oil reservoir. Safest thing to do would be to remove it, drain out the oil & squeeze out that foam thing inside and refill it with fresh oil. That would suck to be injecting water instead of oil; engine probably wouldn't last long like that.
