The dealer just replaced it even after i just replaced it. So 2 filters, caps, and o-rings in 1 month and still leaks. I checked aluminum housing and its fine but i still dont like that plastic caps idea and especially a o-ring setup.

now i did notice that they tighted the cap with a wrench and correct me if im wrong but it should only be snugged tight. Because if you over tight a o-ring it way cause it to pinch. Im going to replace the cap 1 more time but other than that im clueless.

Thanks for all the input.
