That's definitely worth it for $1,200, what's the worst case scenario? Get a rebuilt IP for about a grand and you're into it $2,200 for a good truck with a fresh pump and almost new engine!!

That really is nothing for miles, I just tore down a 350k mile cummins, too hot of EGT cooked the #5 piston and took out the bearings, the other five pistons looked absolutely perfect.

good call, forgot about the head gasket. That's a pretty reasonable fix, too, especially if the head doesn't need to be planed. I did my head gasket and got studs ($300 for studs is cheap assurance!!) at about 290-300k miles but I waited until the gasket blew

I was just saying 300 for the studs, nothing for the head gasket or anything else; I just checked the invoice, it was actually 350 for the ARP's I just bought last week for the '00 I'm working on, they're brand new. my bad.
