I replaced the oil filter adapter housing gasket on my mom's 08' non-VCM Odyssey today. probably the most difficult part was fighting the electrical connections off, I used the old trick of spraying them with silicone spray the lower connection came off well enough, put the connection that goes up to a bracket on the back of the engine stumped me, and I was having a hard time figuring out how you get it off, most videos I found are for the VCM version of this engine, which is much simpler, it's just 3 bolts and the adapter comes right off because there's a seperate spool valve for the vtec/vcm stuff, but on the non-VCM model that vtec solenoid is on top of the adapter. I think I found a video of an Accord or something and figured out what I was looking at was a female connector that is clipped on the bracket, so I had to first unhook the male connector up top and then hold down the clip on the female connector and slide it off the bracket. The gasket had a nasty crack in it, and broke into a few pieces when I removed it.
