Just need the dimensions of the crush washers that attach the oil cooler lines to the oil cooler. i'd like to replace them as I seem to have a leak coming from there (not the lines but where they attach).

 

I had crushwasher problems with my turbo oil lines. Couldn't figure out the sizes, where to buy them, all that crap. Even my dealer (idiots) kept ordering me the wrong ones. In the end, I brought it to a different dealer and told him I needed "four of these" he brought them out after about 90 seconds. I suggest going that route first. Pull them go to the parts dept and hand it to him. If they special order them they will probably be wrong.
