You mean for the oil filter? If so, I remove the right front tire and the oil filter is right in front of you. I bought some disposable small foil meat loaf pans. Stick one under the filter, being foil I can shape it to fit. It collects the oil, when full slice the bottom with a razor and let it drain into a pan.
There's virtually no reason to bother installing a catch can on the 3.5 DI V6. There are no known carbon issues with any of Honda's DI engines, even the turbos AFAIK. Why risk screwing yourself out of warranty coverage by installing an unnecessary modification with no hard evidence to back up the need?
So far on the Pilot and Ridgeline users with the 3.5 DI V6, catch cans have trapped very little oil. Its just not a problem on the V6. Now if you had a turbo 4 cylinder then most definitely. Passport no.
