Try not to breath vapors, and be careful it's very easy to spill it,it melts(leaves residue)on some types of plastic.

Thats right it was. The 2005 3.5 iVTEC can develop issues with the VTEC actuation system because of a plugged screen in the actuator on the back of the rear head (R) near the throttle body.
Honda modified the rubber sealing gasket in the oil filter housing to include a screen that wasn't there in the early 05's to help prevent too much junk getting up to the actuator screen.
The oil filter housing is very easy to remove(4 small bolts), it may be worthwhile popping it just to get a better idea if you have a serious deposit problem. If it does some thick deposits will ooze out on the pre filter side.
If its relatively clean then its a good bet the bottom end is clean enough and you have just a minor varnish issue.
Get a new gasket from Honda, it will have a screen in it.
This job is 30 min with normal hand tools and oil, spark plug changing skill level.
One thing you don't want to see with these iVTEC's is a CEL for misfire and a illuminated VSA light. This combination more often than not is a good sign of a sludge issue that is out of control and has found its way into the iVEC system.
The reason i recommend a higher weight oil is as someone pointed out Kreen is a solvent and will lower viscosity.
These 3.5 Honda engines run high temps in the cylinder head area, short trips are murder on the oil but on these it seems to start a chain of events that leads to deposits and gets out of control quickly.
Add the iVEC into the mix and the head temp on the front head (L) rises dramatically as it does all the work in eco mode.
This is the head where you will find most of the deposits if there are any, it also houses the PCV in its valve cover, you already changed it so no issue there but they do clog quicker than most.

Our Ody is an 05 EX, not an EXL or touring so it does not have VCM but it's a VTEC (or iVTEC...idunno sitting here on the couch).
I will post some picts if I can get the camera to flash at the correct angle to show anything tomorrow in the Sun. I saw another picture of a Saturn view with a bunch of miles on it with the same 3.5 that looked great with regular OCI's.

Yep not all of these have a problem it seems to effect a few and then only under certain circumstance. Once they are clean shorter OCI seems to keep them clean.
Right its an EX it does not have iVTEC so you wont have any cylinder actuator issues. This maybe an easy clean up. Still i would probably still pop the oil filter pad for a look.

Picture I promised. Like I said, not too bad. This was prior to the last change (I ended up taking pictures to use to see if what I was doing was making any difference).
Like I said, it's yellow everywhere, but I don't think it's bad. I just want it silver.
The engine cover says vtec, not ivtec.

Well, the picture upload / link process isn't working for me. This might work...

i think kreen will make short work of it. be sure to get some after pics!!
it actually looks like what ever varnish you had is starting to get soft and dissipate. the syn you have been running is doing its job...

now what is this pic? it looks a little dirtier...
you should try and take your pics in the same position that way its easy to reference
one thing about it, you can see some sludge formation on that bolt head....

Yeah, sorry. The first set was with our Camera, the second was with my Cell phone. Sorry about the difference in angle. That was the best I coud get with my Cell's light.
The Edge has not stopped it and will be changed just as soon as the Kreen shows up. Ugh.
The bolt with the sludge on it was on the top of the first pict (but was clean then).

bob are you sure it was clean or was the whole top of the bolt black and now just starting to clean up and show the gold underneath? hard to tell from the pics becuase its not well lit in the 1st one, and it really just doesnt make sense! you shouldnt be forming more varnish and sludge with good oil and short ocis
The first picture was from two months ago or so. It was when I did change #2 to Castrol Edge (I wanted to see time lapsed pictures of the varnish going away). Then my wife did a trip from Indy to the South East Michigan (Brighton), then the U.P in Michigan, then to Columbus, OH, then back to Indy along with some other misc runs. I just changed the oil with Edge again two weeks ago and that picture was from minutes ago.
I changed the PCV when I went to change #1 on the Edge.

It's hard to say. I would think I would have noticed. This pict is from the first run of photo's as well. It sheds a little more light on the top bolt.

From the others i have seen it doesn't look anywhere near as bad as they did. You may have nipped this one in the bud.
I think Kreen will clean it up nicely.

It doesn't look bad, but in my car, right side, near oil fill hole looked 4 times better than left side near oil return hole,which was all sludged up. So consider worst case scenario, I would use couple short runs on dino with quart of MMO(like 1000 miles), then 2 short runs on Kreen, and piston soak if possible, change pcv valve, clean plugs(during piston soak), and than continue using of MMO for future full time ocis, and forget about it. MMO is like 3$-$4 at walmart, so not a big deal to add it every OCI, and to gas tank.
As I know in Europe, engine flush is done before every oil change,by lots of people, by flush oil(thin oil) or chemicals. Maybe that's why there is more 20,30 year old cars on the roads?

Just wondering, since many thing are done cheapest and quickest way in US. But it doesn't mean best way...
Save for those questionable deposits on the bolt head, the color looks just like mine. A slight gold tinge, but really, nothing out of the ordinary for the miles. I personally would stick with quality synthetic oil without any solvent adds, but will defer to those with more experience for that recommendation.
