Review on Fumoto F109SX M12 1 5 Drain Valve by Loud Forrest

I chose this F109SX Fumoto oil drain valve for my 2017 BMW X1 because it was recommended by the manufacturer. However, its installation meant the impossibility of reliably closing the access hatch in the bottom plate. Even in the least constrained position, the oil would have flowed into the bottom plate and not into the standing pan. To prevent accidental opening, the valve has a two-piece latch. First, it's a spring clip that keeps the lever from rotating. It was very tight and difficult to remove until the valve was in place. I think it would be even more difficult under the car. The lever itself had to compress a return spring to force it out of the locking bolt and into position to pivot to open. Again, this was difficult when the valve was not installed. Given these safeguards, the valve is unlikely to open accidentally (resulting in catastrophic engine failure due to oil leakage). However, I'm not sure it would be easy to work with if I *wanted* to open it. Because of these concerns, I only rated it two stars.
