If you mean the camshaft seal, yes, you would need to pull the timing belt and sprocket off, and if you are anywhere near the service interval for the belt, replace it and the water pump (unless the water pump is very easy to service, and the tensioner.
You will probably need a (gear/sprocket) puller to get the sprocket off and a another type of (seal) puller to get the seal out. You could probably extract the old seal with a screwdriver, but it's not recommended. Get a Haynes manual (around $20) before you even contemplate doing this youself. If you haven't done this before, are mechanically inclined. and have all the tools, you will spend about 1/2 a day to do either the cam seal by itself, or the seal, timing belt, tensioner and water pump. Once you have it all apart, the last three components will only add an hour to the job, and you won't be stranded when the timing belt breaks.
good luck ..ajm

it could also be the oil pan gasket, or the manifold gasket. if it's the manifold gasket, when you remove the manifold to replace it, take the time to clean out the mixing chamber. it'll be filled with gunk and cleaning will improve gas mileage.

usually an "O" ring where the shaft comes out of the box but if the shaft is worn where the seal runs you may have to replace the shaft

Firstly, make sure the seal you fitted is the correct one, sounds silly but I have been given the wrong seals by parts people. It pays to check. Next, if you have fitted the seal correctly, and made sure that the seal is in flush with the housing, then it may be that the shaft is worn and may have a groove in it which was caused by the old seal. Pull the shaft out again and check for this groove in the shaft. If it does have the groove, you will need to find and purchase a steel sleeve which is fitted over the worn section of the shaft and ensures a nice clean and tight surface for the new seal to run on, thus stopping the leak.. Here in australia these sleeves are called "speedy Sleeves" and are available from any bearing shop and auto parts stores. The sleeve has a removable step on it which is used to tap the sleeve onto the shaft ( with a small hammer) and is then removed by twisting it sideways with pliers or sidecutters. The sleeve has a scored edge to help with this. Once you have removed the step, carefully clean up the edge with very fine grade rubbing paper ( wet and dry or fine emery cloth) with Oil applied to it to remove any sharp edges BEFORE you refit the shaft into the gearbox. This ensures that the new sleeve does not damage the seal. Re-assemble everything and test drive. As long as the seal is correct and fitted correctly and the sleeve is fitted correctly this will stop the leak. Have fun..
