We just finished getting the engine back together on my sons 1994 Buick Regal with a 3.8 series 1 engine.
There are 3 gaskets left over in the fel-pro complete head gasket kit. The larger one on the left is for the EGR valve but we didn't take it lose from the mounting bracket.
The two smaller gaskets, I have no clue what they go to. Does anyone know what they are for?
Thanks

Those go under the 4 port vacuum block next to where it says 3800 (or 3300 in my pic). Rather difficult place to detect a leak when failed.

I would pull the ERG and use the new gasket and also the manifold for the vacuum should be done as well.

Thanks for the reply! Good then they do not apply to our 1994 3.8..
Our'* has the vacuum port that uses a O-ring and twist locks into the upper plenum.

Thanks!
The EGR valve mounts to a bracket that bolts to the end of the cylinder head. It is the same bracket that has the ERG tube that goes the upper intake.
Is there any chance of breaking something by taking it loose? WE only had to remove the tube from the bracket when we took the engine apart. WE left the EGR valve bolted to the bracket. There is a tube that comes out the bottom of the EGR and connects to the exhaust manifold. When taking the engine apart, we couldn't get the nut loose that holds the EGR tube to the exhaust manifold so we just took the bracket loose from the cylinder head leaving the EGR valve on the bracket and connected to the exhaust manifold.
Thanks

OK...If it was never taken off and the seal broke it should be fine. I would let it go.
