Not to much has been posted about these, so I went out and bought one and "disassembled" it. Hehe. The construction is solid. The actuator valve is simply a metal plate with a spring and a rubber seal. There is very little chance of it leaking. The only thing that would cause it to leak is a pebble getting stuck between the base and the rubber seal, but I doubt that would happen. All in all, it looks great. I did, however, check the height of the threads on my oil pan for the drain plug during my last oil change, and any quick change valve will stick up about 1/4 inch past the threads, holding oil back. So I'm just going to use my stock heavy duty, very thick rubber drain plug washer in addition to the copper one provided with the sure drain. That will level it out with the threads in the oil pan. So, now I have to go buy another one to actually use, cause I hacked this one up with a dremel to get inside of it
Yes, I have to much time on my hands
