Noticed I had an oil leak in two spots, first being the cam plug which is pretty common on these motors & the second leak formed at the front timing chain cover (driver side). I will admit, I was a bit shocked at 44K & soccer-mom driven to have these 2 leaks. On a positive note, MB of Princeton was just fantastic to work with & a perfect, clean job performed on time.

First I'd heard of this on the 550. Have you provided the data on your repair tohttp://www.truedelta.com/? It is a good idea to do this since all of us then get a truer picture of the failure rates/ problems/ issues, etc.
