    Hi

    Is anyone running the new Inlet Manifold Gaskets - Aluminium Replacement for the plastic OEM ones.

    I am in the process of refurnishing my engine and I suggested to my mechanic that he considered the new Mace Aluminium ones. See link below for details.

    Inlet Manifold Gaskets - Mace Engineering Group

    My mechanic is prepared to give these a go however he some reservations regarding Aluminium being able to "crack" and get a good seal like the OEM plastic ones. He did acknowledge the some OEM ones can fail after 150000kms.

    Anyone had these for a sufficient length of time and distance on their vehicle to confirm performance and durability.

    I've had them in for 20,00 k's/16 months. No problems yet.

    The aluminium gaskets are OEM, they are supplied by GM and supercede the plastic type gasket.

    Plastic gets brittle with age and fails, alloy doesn't. Being the same metal as the intake manifold thermal expansion/contractions rates will be the same which should also be better.

    The Alloy gaskets aren't made from sheet metal. They're a formed soft compound (yet stronger than ACL/ OEM plastic style) that lives well in even a F/I environment

    Isn't it the recommended Holden Coolant that destroys the plastic gaskets? (Dexcool). Use a silicate based coolant and there aren't the problems?

    I didn't think so, rather just plastic becoming brittle with age and all the heating/cooling cycles.

    These gaskets have been used on the Holden V6 engines since 1988, and this problem has plagued these gaskets since the VN model which I think is before this Dex-cool came into use.

    I've not had any other issues on my VN other than intake gaskets.

    Maybe the stuff used in the US is different to what we use here?

    So are you saying that the problem with the inlet manifold gasket is due to a gasket malfunction post the VN series 3.8?

    These gaskets are a must as oem gasket gets older the antifreeze degrades the seal and they start to leak causing a hole array of problems as coolant wicks down gasket into the cylinder casing high Temps cracked heads and head gaskets it also has a negative pressure affect on the pcv and possible oil pressure problems from oil vapour any 3800 over 10yrsold should be upgraded with the alloy gaskets above in my opinion.

    Assuming that our Aluminium inlet replacement gaskets are fitted properly and quality coolant is used, these gaskets will last many many times over the plastic versions.
