Just had to replace a 3400 engine in a 2004 Venture
van. While doing so, we noticed that the intake gasket
is a new part number and design. Here are some pictures
that kind of highlight the differences for those that are
interested in the whole intake gasket fiasco.
First, here is a picture of the old gasket side by side
with the "improved" gasket that came out sometime
last year.

Main difference is the two metal pellets in the gasket to allow
for greater torque on the gasket without deforming it.
Here is a closer view of the "improved" gasket at the water
port section. Note how the imbedded rubber gasket is a
single piece design around the port.

Now, here is a picture of the 2004 design gasket. You can
see that it has one imbedded rubber gasket that goes around
the inside section of the water port, and then a completely
separate stand alone imbedded gasket that goes around the
water port. I like this, don’t know how good it will work, but
it appears that they are trying to keep the coolant from leaking
to the inside of the engine. Even if the gasket around the port
fails, the other gasket should keep the coolant from leaking
inward.
Oh yeah, the intake ports are a spiffy green color now. Probably
simply to aid in identification.
