We have an older 590Turbo with a Cummins 4T390 engine that died while we were using it a while back. In trying to diagnose the problem, I pulled the front valve cover and it looks like the camshaft isn't turning though the starter does crank the engine.
How hosed is it? Is that a zero clearance engine or is there a chance that it isn't going to require a major overhaul. It has 6450 hours on it, it had 6356 when we bought it, they told us it had an in-frame overhaul at about 5000 hours.
I'm not an experienced mechanic but can handle most things with good instructions and manual. I have the Service Manual and Parts Manual for the backhoe.
Any insights, help, or advice will be much appreciated.
