| Can Heat Exchangers be replaced on a 1981 vanagon without removing the engine? |

Till a stud snaps off on the exhaust port. Start soaking all the fasteners with PB blaster.

| If they haven't been off in a long while it would pay to have an Oxy-Act torch on hand. Even a mini Oxy-Act torch would do. You don't need much heat, but it needs to get the nuts to a cherry red. |

| Like Mark says it’s easy until you brake a stud. There only four bolts that hold them to the cylinder head and three they hold them to the rest of the exsust and probably one piece of tin to remove. I would not attempt the job with out heat (oxy-acetylene). So not hard but with out the right tools it would not be easy. John |

^This!! I'm usually just a lurker, but having just finished going through the process of getting the broken nub of a stud off my 81. I do not discourage you from doing it, but patience is your key if things feel stuck.
