Hey guys, well the other day when it was cold out i was fixing some things and well in the process i happen to break something. However i have no clue what it is. It runs into that blue bubble(refer to picture). I think it might be something for my EGT? It is some kind of vacuum.

Also i pulled the plugs today, they look a little lean? What do you think(had a misfire and my engine just has not seemed right lately. Maybe because it just hit 70 grand on Christmas.

BTW: as you can see in the pictures i had to make a new tube(runs across the engine where can i get a replacement for that so i don't have that big ugly yellow silicone tube.

Pictures: its the little broken tube---

Plugs do look lean to me, but just seeing for your opinion, Also flash was on so everything does look a little iffy.

That part you rigged with the silicone tube is the "Corrugated vent tube". Basically a breather for your valve covers/PCV system. IIRC they're ~$50 and I don't think aftermarket places can get them.

Those plugs look fine, they may be the incorrect heat range for your car though, as they do look like they were running a hair hot.
