ok befor the big trip last weekend i replaced the injector washers and return line wahsres. it seems the leaks are coming from the return line washers. i noticed when i got the horse shoe return washers from cummins they wernt the copoer color, they looked more like aluminum. would that have any reason for these things not sealing?

 

If all 6 started leaking after you put new washers in, try using the old ones again.

 

got it fixed i had to torque the hell out of the return screws, i tightned them with the truck running so i could tighten them till they stoped leaking, now my turbo drain line has a slight leak now
