Noticed a few weeks ago truck has oil in antifreeze, just confirmed the other day it's going both ways oil is contaminated as well. From research I've done more than likely oil cooler. I have priced that part, and only comes with o-rings for oil cooler case, and oil cooler itself. Know I will need intake gaskets as well for one thing. I know that there are a few things I would like to replace at the same time, but don't have the money to do the job the way I would like it to be done, and have already been stranded in middle of nowhere for almost 2 mons. At least the truck still runs so hpop and injectors aren't fried yet like I've heard can happen. What do people who have had experience with this think is the minimum parts list I will need for this?
