GM 4.3L Intake Manifold Gaskets Vortec

GM has upgraded this part from the OE design and the new design should address the intake manifold leakage issues specific to this engine with OE design gaskets.

Pros
  • Replacement Parts
Cons
  • Clarity

The metal is good. The plastic is bad. Do not use plastic in motors.

While the gaskets themselves are a great upgrade from the original OE plastic garbage gaskets, the dowel pins are garbage. My gaskets came with both pins knocked completely out of one of the gaskets. Obviously this has to do with both the quality of the plastic the pins are made of and the fact that the spacers are loose in the pocket with nothing in between. While this may not seem like a big deal, it actually is. if you put the gaskets on the heads and then the bottom intake on the gaskets as

Pros
  • Gaskets
Cons
  • Protection

Locating pins not included

They were supposed to include locating pins for proper gasket positioning, but they were not installed or included with my gaskets. I removed the pins from my old Delco 89017866 AC Gaskets and used them in this replacement. The previous ones contained these pins and I have never seen them missing before. It must have been a production error. These are likely factory seconds sold for full retail.

Pros
  • GM recommended replacement part for your GM vehicle's original factory component
Cons
  • Appearance
