So I was finally able to take the TB off, (first Time) thanks to a link I found on here. The front was pretty clean but the back was a little nasty. I've seen worse on here. But got it all cleaned up.
So my question is this. When I took the TB off, right behind where the TB sits (not the TB itself, but behind it) I wanna say intake manifold but I'm drawing a blank, there is a nickel size port on the bottom that loops around to the back. That hole was all gunked up and I couldn't really seem to get it all that clean. Mostly I was afraid of using a brush or something, didn't want anything falling down there. So what is that hole and should I take it all apart again and get it clean? And if so what's a good way to clean in.
I'm trying to get some engine work over the next couple of weeks done before I start a new job. Any extra advice would be welcomed.
Yeah, its on the bottom of the UIM. Its not a rubber tube but a casted metal tube. It looks like it goes up the back of the engine a couple of inches to the bottome of what I beleive is the EGR. If someone posts a pick of the UIM with the TB off I could point to it. I'll see if I can find one 'til then.
