There's no timing chain on a Samurai, just a belt, so there's no oil - or there should be no oil - in the timing belt cover, so no issues with leaks.
The covers are not difficult to change - 4~5 bolts on the crank pulley (depending on the year) maybe another 8 or so around the edges - and there are available from Dorman, so your local auto parts chain should be able to get you one - or you can try Amazon.com - should be $30 or less.
One last thing - there's no such thing as a stupid question - there are stupid answers - we learn by asking questions, if the other folks who know give us good answers - would I be stupid because I didn't know if a small block chevy used a belt or a chain, bearing in mind that where I am, there are very few small block chevies? Lots of Suzukis, but very few bowties.
