I took my upper intake off so I can retorque my lower intake bolts. There was some coolant puddled toward the back on the passenger side. The hose that goes from the lower intake to the back of the throttle body looked swelled, so I wanted to replace it while I was at it. Pulled the hose off and the coolant was shooting out of the top of the stem on the fitting that goes into the lower intake. Put my finger over the top and it came out the side of the stem. So now I need to replace that fitting.
Does any one know where I can buy one? It threads into the lower intake on the passenger side rear. Male thread with a stem if that helps. I have the Edelbrock Performer 5.0 EFI intake.
Do you use any type of thread sealer with this fitting?
Also the inside of my upper intake is pretty dirty. What should I use to spray it out? Throttle body cleaner?
Thanks for all the help!

You should be able to find a compatible replacement fitting at any hardware or auto parts store.

Yes... use the white sealer to install it.

You can use brake cleaner, TB cleaner, whatever you like to clean the plenum. I usually use the cheapest brake cleaner I can get my hands on for cleaning parts. Nice thing about brake cleaner vs. others is that it doesn't leave residue.

Well, got it all back together. No leaks yet. Check engine light is on code 31 EGR. Didn't have it before. Any suggestions?
Thanks
