Hello, you are correct. You do need to start by at least removing the front timing cover. It could be a cam seal or crank seal.In either case, the t belt has to come off. Below is info to see if it is within your comfort level. It can be a bit of a job but not too bad, just a little tight working area. Sliding crank gear off and popping out seal and inserting new is not a problem at all. just getting to it
