    Hi Guys,

    I will be swapping out the intake manifold gasket on my 2008 tomorrow and just wanted to get your feedback on how to prep the gasket. I have a factory OEM replacement gasket, which is made of metal with a coating on it. I was wondering if the proper way to install one of these gaskets is to run a very light very thin coating of RTV around it on both the head and manifold sides, or if I should run a little oil around it, or if I am good to just put it on and go?

    Thanks in advance,

    Fried

    Can you post a close up photo of the new gasket?

    Just curious what you paid for the gasket? List price from toyota is $225 (ridiculous)

    Btw, the their is a maximum warpage spec on the manifold of 0.0039.

    I have access to factory service info, but for some ODD reason. I was not able to find any procedures or torque specs for the intake manifold installation.

    Exhaust, yes
    Head, yes
    Intake, no
    Throttle assembly, yes

    Weird.

    I would not put anything on that gasket.

    Correction: intake gasket $7.20 from toyota

    The $225 was the manifold itself.

    The Beaded steel gasket is not meant to have any other compound on it.

    I dug pretty deep, nothing is listed for Intake to cylinder head. I found the stud installation driving torque of 7.1 ftlb. It likely just falls under general torque specifications for the stud size class and thread pitch in combination with nut classification.

    I don’t know the stud size. M6 x 1.00 or M8 x 1.25

    OK, thanks.
    I know you have been around here for quite a while but I had not seen enough of your postings to determine your attention to detail. Thank you for your help here.
