Question on a 2007
I'm looking at a 2007 4x4 with 126K miles. The test drive seemed fine, however afterward I popped the hood & checked the oil. The dip stick shaft has a good rubber seal inside the dip stick tube. When the seal broke as I extracted the dip stick, there was a noticeable release of pressure? The salesman said this was normal, but I've never experienced that on any other engine. Normal? Why would pressure build up in the lower end unless there was a ring problem or something else? I'd appreciate any comments from experienced owners.
