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. iPhone X ?
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. iPhone X ?
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 iPhone X ?
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.
Where was that illustration located. It’s not shown in my cylinder head info thru my Alldatadiy subscription. iPhone X ?
