You definitely can do most of that other work yourself for *significantly* less than quoted - just takes your time...

Cracking open the engine maybe best left to a pro - I can't comment on cost - but from what I've seen, if it really does need a full rebuild that is not out of the range. Real question is does it really need the full rebuild as others have noted...

I got lucky with mine - I also bought without a PPI .. I could have gotten away without doing any work on it for a while.. I refreshed a lot just because I wanted to, not because it had to be done..
