I know the 3800 series 2 engines had a lot of problems with the intake leaking but what about the series one?
I have a 94 regal with the series one and was just wondering if these engines were prone to the same problem?
I believe that the series 2 problems centered around the use of a composite material intake manifold. Series 1 did not have that.

The series 1 did not suffer the same problems because the EGR tubes enter the upper plenum differently, that said, the series 1 do sometimes suffer coolant leaks from warping where the throttle body bolts on.
Some of the Series 1 engines do use an upper composite intake plenum...but as another poster pointed out, the difference is how the EGR gases are plumbed into the upper plenum.

Ummm, hate to tell you this but, all of those are for a different engine; 3.1 and 3.4 liter Chevrolet built and they apply to 96 and newer. The OP was asking about a 94 Buick built 3.8...
Oops !!! Sorry for the mistake ...
