Not doubting you were cleaning off the reservoir, but they can't leak through glass. Trust me on this.

Your zealous defense of the Ampco oilers is...unusual. Are you selling them by chance?

Please, tell is your experience (hands on) with the Ampco oilers. When you do, you'll find that I won't call you a liar...gentleman don't do that, especially to folks they don't even know. But hey, that's just how I was raised.
