Robert, do you have a picture showing your valve?
I have a Sure Drain on mine, but haven't used it yet. The oil drain points straight down on the 4.0L OHV, so I don't see how it would have a problem completely draining on my truck.
I can see how it might trap a small amount of oil if your drain points to the side because the oriface is small. I bought one for our Toyota PU, but I'm having second thoughts about installing it because the drain points sideways on the Toyota.
