okay give me a second, i am looking at the pic.

okay, sorry i assumed you had a v-6. By the looks of it, kinda hard to tell by the pics but looks like they didn't clean out the ports. The egr ports are under like a little tray on the intake manifold, that or they are freeze caps. I can't tell if somebody has touched them. Do anything on the intake manifold like new or like a socket has been put on them
