i know what it is and where it goes and if you will send
me 100 bucks i will give you the answer... it crucial...
ok, i am just kidding... there are two of those and they go between
the intake and the head. look at the intake gasket and you will see where they go.... i had the exact thing happen to me... one of mine popped out but i saw where the other one was.... so pry your intake over about 1/4 of an inch and put it in....use a long pair of needle nose pliars...
this can be done without taking the head off...
