Maxxforce 13 oil leak

So the final answer on my truck, the oil leak appears to be coming from within the high pressure fuel pump housing. International tells me that that is 12 hours of repair time at $180 an hour. Plus $600 in parts. On top of that starter has fried and while the starter cost 300, they're quoting me another thousand dollars to replace that and degrease the engine.
That'll put me at nearly four grand for minor repairs. That's after spending 1500 on a power steering pump and service last week, and still needing to replace the air conditioning condenser, 8 batteries that cost 300 a shot, and all the other general maintenance that goes with a normal truck.
I'm done.
Thanks for all the advice from everyone.
