So I am in the process of swapping my motor out for the y8, and I can't really figure out what the little plate is on the manifold. I don't really know what this is for. It looks like there is one little hole for each runner on the manifold, but I don't know what the purpose of it is. The whole section is before the injectors, so I don't know what would be mixing or whatever it is. Any help is appreciated. I mainly want to know if gas gets in there to know if it is safe to just use hondabond rather than buying a new gasket. Thanks.

 

You're not referring to the heatshield are you? Maybe my perception of your description is off but that's kinda what it seems like to me.

 

no, it's not heatshielding. I wish I could find a picture of it. It's right before the fuel rail and it crosses all four runners, but the heat shielding would not have holes that pentrate the runners I thought. Maybe it is something to do with cooling? I don't know

 

bump, cause i really need an answer

 

bump for a quick answer

 

Just a suggestion, maybe vacuum lines? I deffinitely think it'd help to have some pics. Can you upload a few or maybe get a friend to do it if you don't have a camera?

 

There's the whole manifold


A close-up of the area in question


And that is the bottom of the 'plate' that goes over it

Maybe now people will know what i am talking about....

 

You have an HX manifold, that is the EGR chamber

part number 11

 

hondapartshero is my hero! Always helping me out. Now, can you tell me what the EGR chamber does exactly?

 

EGR stands for Exhaust Gas Recirculation, it puts some exhaust gas back into the intake during light load cruising conditions to reduce NOx emissions. It's strictly an emission control. You'll have the EGR valve that actually controls the flow of gas into that chamber, and that chamber distributes it to each cylinder.

 

so it's all gases, that's what i wanted to hear

 

Good job! Glad to hear you got some help. Sorry I couldn't be of more assistance though

 

it's all good. i didn't really provide you with as much detail (pictures)
