Thanks Glenn. That's all I can think of too, a solvent to dissolve the oil and flush it away. I think at this point the guys in the shop don't know where it sprayed, thus where to focus their cleaning. They did the normal, thinking it had oozed out and dripped, but I'm thinking that it may have sprayed out into the fan air stream and gotten into the hood liner and other absorbent materials under the hood. Kind of like squashing a skunk, the oil goes everywhere!
