03-07 Spool Valve (VTEC Solenoid) Replacement *Help Needed*

Was wondering if anybody had any info on replacing the Spool Valve Assembly which houses the VTEC Solenoid on an 03-07 Accord.. I have the part already but I'm not sure if I am going to run into any issues when I jump into this. Can't seem to find any info or videos on a newer accord, only a youtube video for a 95 Accord. Any info would be greatly appreciated..

Well I changed the valve this weekend, was a piece of cake!!
I removed the hood to make things easier for myself... had to put the new hood that I had on anyway so it worked out nicely.

The Spool Valve assembly replacement took me all of 25 minutes to complete start to finish.

Turns out there was a sliver of rubber gasket material in the strainer which I think was causing my problem and possibly why it only happened intermittently but time will tell..

I've only put about 35 miles on the new assembly so far, will let you know if I have any further issues

Yup, had a harder time getting the clips that hold the wires onto the valve assembly off then I did removing the actual part You cant really see whats going on back there, gotta kind of just feel for the bolt, get the socket on and loosen/tighten it blind. I used a regular 10MM deep socket and 3/8 ratchet with ease.. So much room back there compared to the video I saw on the 95 accord!!

CEL was throwing code P2647: Rocker Arm Oil Pressure Switch (VTEC Oil Pressure Switch) Circuit High Voltage
The car would get to 2500-3000 RPM and under ANY type of gas applied would bog and shake violently almost like a rev limiter being hit at 3K rpm..

Did some research and since my oil was at a normal level, next step was replacing the vtec solenoid. Seemed easier and a little more sensible to replace the entire spool valve assembly which houses the solenoid. I could have just replaced the gasket, but the guy at the dealership told me that the VTEC solenoid was $80+ and the new entire spool valve assembly was $111. I wanted to see what the screen inside the old assembly looked like anyway so I just went for it.. Lucky for me that I did decide to replace the entire assembly though as I mentioned I found a big piece of gasket in there which I think was causing my issue.

I've been looking into replacing my vtec solenoid, I cannot find a diagram/picture as to where is located in my 03 v6. Anyone can point me in the right direction? Also once I take it off, is it going to leak oil?

I replaced the gaskets on mine, recently. Not sure if V6 will be the same, but on my i4, it was facing the upper passenger side firewall, way above the oil filter. I had to lay across the engine to get to it.

Get under your car and look up. Also hold a phone or mirror back there.

Lastly does this leak oil when I take it off? Meaning, would need to do an oil change or no?

The spool valve for the V6 is together with the oil feed pipe/filter as one assembly. I'm looking to do this myself soon because it's leaking oil. I heard from the TL guys that you don't have to drain the oil in order to do it, but since I'm going to do an oil change soon, I'll just do it at the same time. There is one oil pressure sensor you need to unplug in order to take the spool valve + oil feed pipe/filter off.
