Just had the oil changed with synthetic about a month ago, and now it's leaking oil. Took it in, they thought it was a valve cover, but after digging further they're not sure, so they put some dye in it and sent me home for a few days. I'll bring it back and they'll purportedly be able to tell where the leak is. I've heard of this before, but isn't 64K a little early in its life for oil leaks?
