Anyone know what that is a sign of Just wondering, because I noticed I was leaking coolant from there so I replaced the gaskets... (Speaking of which when I seperated the TB and EGR a few OZs. of coolant came out) Is that normal?

Thanks

Are you sure its not carbon build up?

As for coolant... the EGR is kept cool by pumping coolant through it.

you are probably running the EGR system, it takes exhaust fumes and re-routes it to the intake, exhaust has lots of oily crap in it. The hot gases hit the relatively cool intake tract and the oily stuff gets deposited....

just like in your bong!
