The distributor Cap and Rotor needs to be replaced as it will wear off, although I cant find the info on what is the service life is like.
|Left: Old, Right: New|
U can see the wear on the rotor and contacts on the old cap and rotor on the left compared to the new ones on the right.
The cap and rotor I got (thanx to Amos again :) are for my distributor TD84U. For the B16 engine, the TD44U and TD84U can be used; the only difference between the two is the size of the housing with TD84U being bigger while the internals seems to be the same. There isnt any difference between the two, other than the size as far as I know.
1) Remove the cables from the cap. Do remember with the position of the cables before removing; clock-wise from the bottom left plug: 1-3-4-2.
2) Remove the three screws around the cap.
Remove the cap and u will see the rotor.
Crank your engine, to get the rotor in the position shown on the left. This is so that u can assess the screw holding the rotor in place.

Once u remove the screw, u will be able to remove the rotor.
Just reverse the process to install the new cap and rotor.
