Are these filters clean-able? I see some degreaser and conditioner for my air filters, and they look to be about the same material, so I am assuming they can be cleaned. I have positive pressure in the crankcase on my port CAT 3196, identified in the survey, but the oil analysis is great, so he suspected it could be a clogged filter. While bringing the boat home, I had massive oil seapage from the port engine, so I am thinking that this might be the problem. There is also some oil residue under the port side filter. Any help would be appreciated. Thanks.

OK, so I cleaned it, but it was not very clogged. Are there any other things I should look into that could cause excess crankcase pressure. The survey indicated 2 p.s.i.
