Really? Bone cold motor? Hmmm. Here's my routine now that I think of it. Go for ride, park it. Grab chain lube, spray and walk. Grab tin foil, touch header, still warm, crack oil pan bolt, let it drain, crack filter, watch it drain, walk away and get yelled at by my wife for stealing her tin foil, come back and fill.
So your pan probably works great, would save me an earful from the wife to boot. I'll have to try that next time.
I may not have a lot to say but it doesn't mean I don't listen.
