I have a 2006 Subaru Legacy 2.5i (183,000 miles) that is leaking some oil around the spark plug wires. The mechanic said I should replace the gaskets and spark plug seals. He said something about one side being fairly easy to get to and the other side on certain Subarus requiring one side of the engine to be lifted to access the valve cover. Does anyone have experience with the 2.5 engine in a Legacy and know if it can be accessed for DIY without lifting the engine? I don't want to start it if I can't finish the entire job. My dad and I have done about everything else on a Subaru, but neither have done this before. Thanks.
OR another question: I'm not losing any oil between changes. I didn't even know they were leaking until he told me. Should I even bother with them at this point or wait until it's a real problem? I keep a good eye on oil levels and I would see any changes.
