Is the metal PCV hose that lead from the back of the intake manifold to the air intake (see photo below) supposed to be hot as hell? I nearly got a second degree burn from the sucker yesterday. It's isolated from the intake manifold via a rubber hose so I'm surprised it's so damn hot.
Speaking of heat...has anyone experimented with removing the hood insulator and/or panels that cover the periphery of the engine bay?
the J32/J35 is known for heat soak.
Engines produce temps upwards of 500 degrees.
all that heat is sitting right there.
and yes, any thing you can do to reduce under hood heat temps, like taking off the hood insulation and the plastic covers will help....
its like you know what to do, you need that push. take off the covers and hood insulation.
Only reason I haven't removed the covers is because the front two have rubber weather stripping on them. Removing them would allow water to be forced in.
If that tube is so hot, that means hot air is being forced into the intake. Could I disconnect it, plug the hole on the intake, and put a filter on the PCV tube?

you can do the throttle body coolant re-route, so that the coolant doesnt circulate in that area...
*edit, thinking about it further, you could put an oil catch can on that line...
I don't see it in your photo, and the 3rd gen tl may not have it, but a lot of honda products have a metal coolant line attached to the pcv and/or breather hose. The heat cuts down on sludge. Some other manufacturers use an electric element inside the hoses. Actually, after a second look I think there's a coolant pipe under it.
If I recall properly, the engine cover, at least the part that is covering the intake, has what looks like air-channels which route the air into/near the intake. I don't know how it would be removing that section of the cover.

That's right. I forgot about that. I wouldn't be adverse to re-routing it or eliminating part of it, such as the resonator, but I heard that's a PITA to do for whatever reason. I have a second vehicle to drive though, so I'd be up for the challenge if it's worth the effort.
The coolant pipe from the engine to the throttle body follows that pipe underneath (smaller diameter hose) to help prevent the TB from freezing in cold weather.
