    Intake gasket thickness

    im curious if anyone knows how thick a new, or uncrushed intake gasket actually is....i have a crushed one on mine, but looking at the rest of my intake gaskets their all maybe a 32nd of an inch taller than my intake itself....and i dont think that is near enough to seal

    Easiest way is going to be to replace them. Its fairly cheap, and you wont have to play the guessing game on whether or not they are still usable.

    well i have the intake gaskets on order....and should be here tomorrow...but im just curious if i actually have more than 1 intake gasket thats not useable. one of them is actually flat and even with the intake manifold itself, and the others are about 1/32'nd of a inch taller than the intake itself. so i was just curious how much a new intake gasket sticks out of the manifold

    Ive had my intake off more times then I like to remember, they all seemed to stick out every so slightly. Pretty much what your describing. They are supposed to stick out slightly and your probably making a wise choice on replacing them. Maybe someone has a measurement for you, I do not. Other then that, I would say your about to find oout how much new gaskets stick out

    They will be like that after torquing. I should probably replace my gaskets next time I have my intake off as well. What was the total price for the gaskets?

    29.99....felpro set from autozone

    yeah i just hope that the new gaskets will fix my intake/vacuum leak im having. they all are smashed like i said, and i had to intall/remove my intake 4 times in a week, so im just hoping this is insurance against a leak again

    Well its a start.

    I saw you think you MAP sensor is moving? What intake? That can cause a vacuum leak very easily and was my number one complaint on the FAST intake. They have no provision for any kind of lock for the MAP sensor. BS for such a high dollar intake.

    stock ls1 intake...the block that snaps into the intake wobbles, and so does the map sensor itself. i removed the map sensor cleaned it, and stuck it back in, and it has a really good seal, but am curious bout that whole block that goes into the intake itself

    got my intake back on, torqued down and started....shut it off and restarted, back to its popping, and sputtering. pulled a code p0107...which is low voltage from the map sensor....got the volt meter out i have 5v at the harness. so the sensor is dead
