I've owned my 98 over a year now and this is my third oil change and I've noticed some leaks which I was told by my dealer was the valve covers (I've also confirmed myself with being under there).
There was a theory from my BMW days where people who started using fully synthetic oil (after years of base oil) had leaks like mine. This seems to make sense but I don't know what type of oil the P/O used.
Has anyone else ever experienced this? Another reason I like to DIY oil changes so I can are what's going on. Car has 143,000 so I'm not surprised it has some leaks and feels like it needs motor & transmissions mounts. Can't wait for warm weather!
