I bought an 07' LE CC 3 weeks ago with timing tensioner problem. And had it fixed under warranty. One week after I got it back while changing the front diff oil I noticed oil running out of the timing chain cover. So I took it back in and they found the leaky seal and fixed it. I haven't had it back a week and guess what its leaking oil out of the timing chain cover again. So I'm taking it back to the dealer in the morning. Is there some weird seal in there that is hard to get seated or does Wilmington Nissan just suck?
