First, this may sound like a silly question to ask, but I have to ask to know.
I currently have a '96 Ranger 2.3 / 5spd that was purchased new, and have been driving it for 337,000 miles. Today, I went to look at and test drive a 2008 B2300 5spd that is for sale.
On startup of the 2008 23NS, the first thing I noticed under the hood was how loud the engine was compared to my '96 2.3. The 2008 sounds like a loud fan and valvetrain noise at idle, where-as my '96 is a soft quiet idle.
I know these are two completely different engines, but has anyone else ever owned both the Lima 2.3 and the newer 23NS that can give me their description of audible differences between the two while listening to the engine run with the hood up? I don't know enough about the 23NS to know if this is how they sound normally, but I can pick out the sound of a good running 2.3 Lima any day.
On the test drive of the 2008, it sounded like a typical 4cyl from inside the cab, and felt like it ran smooth. Didn't smoke, and had a little more power than my tired Lima 2.3. I held off on purchasing it today until I looked into the engine sound. It could be just the way these engines sound, but I also don't want to buy a truck that needs a new top end.
Short Version: Are the 23NS's normally louder than the 2.3 Lima's at idle?
