'Sweating on a seek-oil dam' is a terrific line, using a term for a lubrication device on a loom that only a mill worker would know."

From...er..,Brian Peters, in a previous post.

"Sea coil" has nothing to do with mill work. I've also heard the term used with "seek-oil engines" that don't have an oil pump. May be similar, may not. It would make sense to have a dam to collect oil to lubricate machinery.
