  I had the same thing happen at about the same hours on my TSIO550E as well.
  My cam and lifters were pitted and flaking.  I too found out about it by
cutting open the filter.  My crank was fine.  Both my turbos were gone too.  I
ended up needing a new cam and decided to go with a Magnum for more power and
also went to Gami's while I was at it.  Gami's should be put in after you fly
it the next time though so you can give them the proper stats of what each
cylinder is doing.  After the rebuild and Gami's it was a great engine.  Just
ask Bryan Burr as he has it now and I now have a Walter in it.
  
  It turns out the problem was diagnosed as intenal corrosion problems from
what the engine buys call improper storage from the previous owner.  I am not
sure where you base your plane, but mine was based in Florida before I bought
it and this is where the problems started as best we can figure.  The biggest
problem is infrequent use in high humidity areas and not using a good oil.
  After this I would not consider using anything other than the new Exon Elite
oil as it is the best at corrosion protection.  Phillips is by far the worst,
even Shell is not very good.  You need to run the engine atleast once_filtered
a week (flying it not just ground running), preferrably twice according to the
experts.  I believe that most IV's do not fly this frequently.
  
  With all the "water" problem you have had, I feel confident that you have 
the
same issue.  So after your rebuild, use Exxon Elite, fly it once_filtered or
twice a week and you should be fine on all counts.
  
  Enjoy,

   My history with this engine is very spotted;
  
   At 0 hrs. the fuel control lever would not move smoothly so the fuel
controller was replaced before engine start up. In service date was Dec. 2001.
  
   At 110 hrs the first Alternator flange broke and caused and oil leak.
  
   At 170 hrs a Right Mag. failed on the preflight runup and was eaten up from
moisture. Replaced with new Mag.
  
   At 215 hrs the Second Alternator flange broke. And the engine failed the
Topcare compression test on 3 cylinders. Checking all six exhaust values
showed out of spec. valve stems and undersized guides. TCM replaced all the
cylinders.
  
   Now at 298 hrs the Right Mag. had moisture in it and both Mags were given
the 500 hr inspection and put back in service for the Ferry flight to Visalia.
Hardened iron chips were found in the filter and determined by TCM to be
Lifters. This led us to the current lifter inspection. I had previously paid
to remove the Mags and Alternator, borescope the gears, overhaul the Mags and
reinstall for the ferry flight.
