Ahhh yes john_bud, you have last years book. You should get a new one as there's some good stuff not in the older one. But, don't throw away the old one as there's some info not in the new one. As you could guess, the only thing I ever throw away is my underwear after an accident.
Working as a construction mechanic for many years I was many "blisters" on the hyd lines. I do not remember ever having one that had oil in it. I would poke a little hole so that the blister did not grow. I always just figured that it was air in the processing that got trapped between layers.
