I purchased a new painted and ported Intake manifold on the bottom theres hex head plugs that need to be installed, does anyone know what they should be torqued to? I want to make sure there nice and tight so they don't leak or fall out after installed. Thanks

 

I'd say 20 ft. lbs. would be plenty. There should be a heat shield over those hex plugs, so even if they DID fall out, they would be contained. The plugs block off internal EGR passages.

 

I got the heat shield also but i need to reuse my old bolts for that. i just want to make sure i don't over tighten them.

 

Takes more than 20ft lbs to get them out..... they are a tappered thread I think so just tighten them down hard.

What are you thinking.... Hand tight with a 3/8 rachet or should i use a impact? Also should it go down flush or should i still be able to see threads on the plugs? Im also worried about potentialy cracking the intake.

 

Just crank them down good with a ratched. I don't mean to twist them to within an inch of their lives, I mean just crank them down to where it feels "right".
And if it were me, I'd use anti-seize. Lightly.

 

Just screw them down tight by hand with the allen wrench. If you're worried about them rattling loose, use some non-hardening sealer on the threads. They're not that of a big deal.

 

Ok thanks for the help guys, i just want to be sure they will be tight enough
