Well it's 5 below right now and I braved the cold and pulled off my oil return line from the block and turbo. The fittings I made were half inch. The stock fittings are 3/4. Now normally that would be fine but the hose I had the local tractor supply store make necked way down by the compression fitting. So back to the drawing board on that. I'm glad i asked the boys on the 22rtetrucks.com board what was going on. they have helped me out a lot. So add that to the top of my list of things to do.
