    Intake R&R

     



    Hi guys,

    Stupid questions but I haven't done it before...

    I'm going to pull my intake to check lifters and want to know how much and where to put sealant (planning to use black RTV, is this right?) when I put it back on. Same sealant for the bolts? How much to torque the bolts? What is the correct torque pattern?

    Aluminum Holley Strip Dominator intake and aluminum TrickFlow Oval heads... Going to use Fel-Pro 1212 gaskets.

    Anything else I need to look out for? As for checking the lifters, I figure rotate the crank to pull each rocker when fully closed

    Thanks,

    -Chris

    wipe with thinner till dry and i put a 1/8 or so bead on the intake and a 1/4 to 5/16 bead on the block then it sealed take your finger wet it and just wipe the inside the dist hole just a wee bit when the intake is down so the dist will not get in the way of the rvt . just hit the threads with a small amount of rtv to hold down any oil wicking thru the bolts .i have the snap on built in tq wrench arm start in the center work your way out in two steps then get it hot and give them a 1/4 turn should be 15 or so i stop when my arm clicks on the bbc main bolts my back go s out them i know there at 110 for bolts

    thanks, pat... i got a ways to go to earn my calibrated arms and back
    the bead on the intake and block are these at the front and rear? do I use any rtv on the sides between intake and heads? do you put the 1/8" bead on the intake same places as the 1/4-5/16" bead on the block?

    thanks again

    i like to make a small bead on the intake i feel it works better that way so it stick better. then a bead on the block rails in about the same spot you can set the intake down and draw a line with a sharpy marker before you put down the RTV i like on put some around the water ports as well then beded the intake gaskets in to the RTV i use tape to hold the intake gaskets from moving put it were the intake will not get in the way so you can get the tape off when done. i like some slip on the intake .i use a thin coat on permatex form a gasket on the port side i like this for that but that just the way i do it
