There should be a 14mm fastener on the left side from the actual OCV solenoid. It is not even a bolt, it's more like a nut (refer to the attached photos).
Maybe you should also try cleaning the OCV solenoid itself. And also take a look inside the engine, since those had some troubles with the oil sludge build-up..
i really appreciate the info. here's a pic of mine, a little different. This looks to be the bolt. Any ideas how to clean the inners let me know. I've changed the oil, PCV, air filter.
Figured I would pull the solenoid and clean it, same for the filter. Couldn't hurt?
It is a bad idea to try cleaning oil filters, those just need to be replaced with each oil change. Part Number for the filter that you need is 90915-20003. It is just $4.34..
If you are going to remove the OCV filter, you might as well remove the solenoid itself and give it a good clean. And remember, there are two sets of OCV solenoids and filters in each of the heads, and they all need to be cleaned.
For now, you can try peeking inside the engine through the oil fill plug. If it is really dirty in there, you will have to remove your valve covers and clean it from there.
Also, I know that there are lots of products meant to clean the insides of the engines, like this one, but I've never actually tried those and cannot say anything definitive about it.. Maybe someone else can chime in.
Since you are taking the OCV's out, might as well check if its operating when voltage is applied. (12v)
Couple of make shift wires and a 12v battery source should be enough to check.
That would mean there are (4) solenoid and filters. They must be on the other side by the PCV valve. Here's a pic of the 2nd one I found, can't see the filter bolt, hidden by the hoses.
Sincere apologies, I thought you were writing about a standard filter..
OCV filters don't need to be replaced unless if they have some physical damage. Otherwise, you can just use a toothbrush and some break clean to clean those out. The same goes for solenoids, and as Nad1370 wrote earlier, connect them to your battery first to verify that they are working.
Just in case, Part Number for both OCV filters is 15678-20010.
[EDIT]: I wasn't able to get pictures of that bolt, it is really hidden there, and I really didn't want to take my intake apart. However, I was able to find this post that shows a step-by-step procedure on how to remove, and then re-install those OCV solenoids and filters. To make your life that much easier though, I would really suggest you to take off the intake box and the hose, since it will give you much more room to work.
Those are your heater core hoses, so I won't recommend disconnecting them without draining the system first. If you will remove an air box, you will have plenty of room to get there..
