So, the dealership cleaned them out yesterday and said that they use a can of compressed air with an 8 to 10 inch tube attachment that they stick into the holes and blasts out the clog.
Anybody heard of this? I'm going to run by the dealership and ask the parts guy about this. He should know.
Didn't know if anybody has used any of the snakes that are for sale on ebay with any luck.
Or, have used air to blow them out.
Thanks.

I'm a Nissan tech and not Infiniti, but if it has the same drain fittings as the Nissan line (which I strongly suspect it does), neither air nor snakes will prevent the problem from recurring. See post #16 here for why:
