The new to me 02 Xterra with 130k has an apparent RMS leak so my take-possession OC was Napa Gold, 5w-30 Maxlife, and 1/2 bottle of AT-205 (because of the 3.5qt sump). At 3000 I changed oil (same) and added the other 1/2 bottle of AT-205 but on advice here kept the NAPA Gold filter for another 3000. At around 5000 on the oil filter I started to hear a bit of cold start clatter that wasn't there at all. Not loud and in 2-3 seconds it stops. The leak has slowed considerably but not stopped. Cold start right now means 70f morning temp. What's going on in there?
