 Bob- I had the same problem getting a early turbo engine apart- I used 2 or 3 cans of pb blaster on it makingsure to hose down everything that could possibly be frozen, including the base of the cylinders. After each spray downsession, I lightly tapped the pistions and barrels with a hammer- the ringing from the hammer taps helps the oil seepinto the stuck parts. After a couple of weeks of spraying and banging (NEVER hitting anything hard enough to dent orchip anything) the cylinders finally un-stuck them selves from the block, and was able to remove the rods. If you trythis, remember, its the ringing of the metal that does the work, not the force of the hit!Kevin Nash
