LS3 Intake Manifold Gaskets?
Can someone please tell me where I can buy the new 2011 LS3 camaro intake manifold gaskets?
When I took the plastic and rubber gasket assembly that came off of the car to the dealer they could not find the part number nor the correct gaskets. Does anyone know why or have you experienced this before? What is the correct part number for the assembly? The dealer says the part number on the gasket is not a GM number and google is no help. I have owned the car with 0 miles on it so no one has changed it. Can anyone help? Paul |

How could the dealer not find the gaskets? Makes no sense.

I didn't look very long but couldn't find the GM part number. When I replaced mine, I used FAST brand as they were cheaper than the GM ones. |

Plastic and rubber assembly? The gaskets are just o-rings in the intake manifold on an LS3/L99. Only the truck intake manifolds use a plastic and rubber assembly.

Intake manifold gaskets
This is what I mean, no one really knows.
In the Magnuson supercharger installation manual it shows you removing them from the factory intake and snapping them on to the supercharger. They are not like an LS1. see image. Can someone help? |

Also there is plastic on the inside (runner) of the silicone gasket meaning if you can replace the orings i would need 16, one on each side of the plastic.
I have built lots of LS motors and this one has me stumped... |

The only number on the assembly is 28104494 which is not in the GM system.
Again please help. |

The GM part number for the LS3 intake gaskets is 89017585. It comes as a set of 8.

Unfortunately you would be wrong...
2011 is different than 2010. No recesses in the intake to hold the gaskets in place... The GM techs have looked at the possibilities to use these and they will not work per the dealer but they still could not find the right part. Still looking for the answer... |

GM part number you want is 89060434.
According to this engine build link, this gasket is used for a 2009 Escalade 6.2. It is in GM's system, just not for the Camaro. It is only used on trucks. WTF Evidently GM is substituting parts but doesn't know it. I would let your GM dealer know what you found. Maybe they can get it fixed. I have a 2011 GM service manual and it clearly shows the intake gasket as 89017585 which is the 8 piece set. I would call Magnuson. Maybe they can shed some light on this. At least now you can get a new gasket.

Actually I am not wrong. Let's be clear on what exactly you are trying to accomplish. Are you saying that you removed your Stock LS3 Intake Manifold and it had the plastic snap-on type gaskets and not the rubber inserts that fit into the groove on the intake? I don't care what Magnusson uses or the Escalade. You asked for a part number for LS3 intake gaskets. |
