Hi,
 
Recently my 1985 Vanagon started = idling rough (that is an understatement).  I bought a compression tester and = checked the cylinders.  It turns out cylinder 4 has a compression of 75 while = the others are >130.  After dumping some oil into the spark plug = hole, the compression jumped to 175 then slowly fell back down.  So I want to = remove the engine and take a look.
 
Here is a few questions about the = removal of the engine:
 
1.  How heavy is the = engine.  Once I get it off the van, is it staying put?  Or can I move it around?
 
2.  What type of jack(s) should I use to remove = the engine.  I have a hydraulic jack with a 6 inch plate on top.  = Will that work or should I buy something else?
 
3. Once I remove the engine, does it take any = special skill or expensive tools to rebuild an engine?  Is it something I should be = able to do with a copy of the Bentley Manual?  Any ideas on where to buy replacement parts?
 
Thanks,
