Great product so far. Watched the video 3 times before installation. Shame theres no 200 video. So after pulling the OM breather off I placed the GSL unit in place, being extra careful not to drop anything into the engine. Guess what, a washer and the bolt fell out of my trembling fat fingers. But not in the engine but outside down into the valley. Why are there so many loose washers that could surely be held insitu by an O ring or something. Anyway that was my fault. I button it up and off I go driving around. Only to see oil dripping under the car the next day. So the next day I pull it all apart and I realize my rookie mistake. The rubber seal that came out with the OEM piece has to be reinstalled into the engine then the GSL unit gets bolted on. Went back together easier the second time. I've done just over 1K klm's since then and no problems, and since it drains the oil back into the engine, I won't have to keep topping up the oil. Another great engineered and built Aussie bit of gear. Congratulations.
