I had a run away in my truck and ended up replacing 2 injectors. It was dripping oil before out of the flex pipe for the stacks and I thought the injectors would fix that. Now it is pouring oil out of the flex pipe. Could I have a bad turbo? Or what else would cause this. Also, now the truck take a lot longer to start? Bad oil pressure? Where could i be losing the oil and how should I go about fixing it.

 

Sure sounds like the turbo is leaking the oil...Here is a rebuild kit from RiffRaff
I'd rebuild the turbo, then see how the starts are. If still slow to start you might want to check glow plugs, glow plug relay, oil level when cold in the high-pressure oil pump (HPOP), and the low pressure oil pump (LPOP). If you decide to check the LPOP, you might as well just change it out with a Melling pump and be done with it. When cold, the oil level should be within 3/4" of the top of the HPOP.

 

Yup bad turbo seal. You can R & R it or rebuild if you have the tools for the turbo seal.
