Glad that was all it was. Yes, they do sound good, like a small block version of an E9. Mine has just a little lope at idle if it is not in 4 or 5th gear and the splitter in neutral, just a little drag and it smooths right out. I like the slow lope only about 50 rpm's difference but noticeable. I didn't have leaking injectors but I have had to weld a few leaking injector lines, no new ones from Mack anymore. They make a mess in a hurry only way I knew was it was loping a little more than nornal... and the big puddle under it... LOL

Put that old V8 to work.... just baby it, parts aren't around like they use to be.
