I second the head gasket. Your setup would be more than enough to pop it.

 

I finally gave up and took the truck in to Hamilton Diesel up in Liberty Hill and had them take a look at everything. We ran it real hard and couldn't find anything outta whack. Guys there said it was probably just from a different fuel spray pattern of the injectors. Anyways, they gave it a clean bill of health, so I'm just gonna chalk it up to me being paranoid. Reading everyone else's posts about blown head gaskets, valve seats taking out turbos and such kinda makes a guy that way! Thanks for everyone's help and I'll let ya'll know if anything turns out differently.
