Do you mean this ? Since mine is transverse layout, by right it should be easy to spot, however there are too many shit hoses in between, so its hard to look at. Do all 4 bangers have this half moon seal and it it quite close to bell housing ?The pic below is the same engine in my pajero which is running timing chain. Notice the black piece where the cam cover meets the engine head. It got that seal at both end.

Below is the same engine in my waja which uses timing belt. At the bottom right view angle u can see 2 round black (one bigger than the other )seal/plug at the top portion of the engine. Its to be removed so that the camshaft can be held in place during timing belt replacement.
