Woke up to a puddle under my truck!

A couple nights ago in central Texas, I was awaiting my morning delivery appointment, so I decided to camp out in a small town's Wal Mart parking lot. When I woke up the next morning, I smelled very strong diesel fumes and when I got out to do my morning inspection, there was a pretty large puddle of what I figured was oil, fuel, and coolant.

I have had a small oil leak around the oil pan gasket, but this was much worse, as I figure there was about a gallon of liquid on the ground. At the time I saw it, there was no oil leaking, but the coolant reservoir was overflowing, and the pipe behind the turbo looked like it had oil coming from it. I have done a little research and found that the "oil" behind the turbo was likely actually diesel from idling at low RPMs overnight.

I immediately called the boss, who scolded me for not only idling overnight which my trainer said to do, but for not putting it at "high idle" at about 1000 RPM instead of the "low idle" 600 range. Anyway, he advised me to run at high idle, check the gauges, keep an eye on anything else that might be leaking for the next 20 minutes. Nothing else happened.

Anyone care to give their thoughts on this? I've only been driving 3 months and don't really care to blow an engine. Just last week I was commended for being able to save the engine after one of my injectors failed. Here are the main details:

2000 Western Star with a 3406e 14.6L Cat engine. Recently got #4 injector replaced. Check engine light appeared soon after which showed my intake manifold temp sensor was bad, got it replaced. Check engine light returned, can't find a source of the problem this time. Camped out overnight with air temps around 73F. Upon camping, oil temp was roughly 200F, water temp was around 185F, oil pressure range from 50-75 PSI idle to cruise speed. Idled low overnight at around 650 RPM, as I had done every other night since starting to drive, without any issues.

Let me know what you think!

 

Well, soon after this episode, the truck caught fire near San Antonio, so I'm assuming things were related in some way. I think we lost an oil cooler and the oil mixed with the coolant, and spilled out the overflow onto the turbo (the overflow didn't have a drain tube attached). I saved the truck, much to the dismay of my boss, and was out of work for about three weeks waiting for it to be fixed.

It runs pretty good right now, but there seems to be a slight air leak coming from the vicinity of the fan clutch that needs to be looked at.
