When I installed the BSH can I also installed the BSH Dual Boost Tap in the other (passenger side) PCV outlet.
As stated before, during cold weather you need to check/empty the can often because it will fill up quickly with water in addition to oil due to condensation caused by hot/cold cycling. During warmer weather, I check it when ever I check my oil, in other words, whenever I fill the tank.
I use a large basting injector/syringe. Cut the tip off and plug the holes in the injector portion. You can easily make one using a large syringe and a piece of vacuum tubing. They sell the exact part on line for around ten bucks. I prefer mine with the rigid extractor rather than the flexible hose version. Also because I had one laying around gathering dust. YMMV
