As I stated before I looked the cylinder all over and found no cracks. I have removed the cylinder and valve again an still can find nothing wrong with it. So.....searched the world over and found a manual I could read on-line. By the book there are 27 steps to correctly adjusting the steering. Step 16 states the cylinder should not bottom at either end and steps 25-27 gives the final adjustments. It builds pressure when it bottoms thus my blowing fluid out the end. There should only be 70-80 psi when not bottomed. You find the spot where it bottoms and adjust the stops to prevent it from bottoming out and building that pressure. Thanks to being an old truck I now have a leak in one of the hoses after suffering the greater pressure. Tomorrow I am getting new hoses and will make the final adjustments and problem should be solved. If anyone else has this problem I hope this information will help them too.
