it just presses in.  There is a ridge about 1 1/2 inches up from the end of the dipstick housing---the housing is the male end and slides into the block part and stops at the ridge.

Is this a big block we're talking about?

It bolts to the header on mine

i guess i should've asked what it was going in, but, this is what mine looks like.  some have a clip that will bolt to the engine as well....but like this, mine just is tapped into place....
