Is it possible for you to post a pic of the area you are talking about?

If its one of those tubes that goes through the TB, its a PITA to repair, and you may snap one of those tubes... Lucklily for me GM still had the tube I broke

Yup he has the alluminum one piece...

Its starting to sound like the intake gaskets are going...

But a picture would be worth a thousand words

Yes UIM.Cant find daughters camera but I am going to do the UIM gasket as it is def seeping so I was looking for tips as I am going to use the HAYNES, I know get the chiltons but haynes will do as I also have the BC family if I run into trouble.
I am going to get UIM and front valve cover.I will go to dealer for UIM gasket I guess or check part source, but I have a valve cover gasket can any one verify part #25532619 for my 1990.
TIPS TIPS TIPS please

While you are there..it would be an injustice if we didn't beat you into doing the lower intake gaskets as well. Just for peace of mind.

see if any of the local parts stores sells Fel Pro gaskets... You will be able to get the valve cover gaskets and the intake gaskets... Both are very good quality
