In my opinion, it depends on mileage. If the engine has less than 100k miles on it, then doing a repair instead of a full rebuild is sufficient. Otherwise, I would lean towards a full rebuild, depending on the other metrics of the engine - oil pressure and compression.

So, this sounds like rings. My question to rest of the vanagon people
is about general rebuilds.
First, I was surprised to see symptoms that look like rings, when
there are so many other things that can go wrong with the waterboxer.
In my own situation, my first engine had severely worn main bearings.
I believe this is fairly common. I've also heard conflicting reports
on the effectiveness of bore-aligning the case and installating new
main bearings.
My own situation was that I had low oil-pressure on my first engine.
I cracked the case to check out the problem, verified that the main
bearings were really worn, then priced out the cost of the bore-align
and parts. I'm thinking that it was a bit over $400. Yikes... since
other parts of the engine were questionable, I bought a complete used
engine on the ebay for $150. I installed that and have been using it
for a year with good reliability and good power. However, one of the
cylinders if firing funny.
I suspect that one of my rings on engine #2 might be messed up and
causing this odd sound and misfiring problems. I've tried to isolate
the problem with stethoscope and have changed the lifters. However, I
think that I'll eventually need to crack the case to check it out. I
already have a spare engine seal kit. However, I'm reluctant to open
the case of my working engine #2 and check things out.
My question as relates to Blake, is it really cost-effective to do
only a ring change on a waterboxer? Or, does he have to go in there
and bore-align the case, put in near bearings... basically do a full
rebuild. The answer for Blake's situation will give me info on how to
deal with my own situation and help me decide when/if I should crack
the case on engine #2 to change only the rings, or just go ahead with
the rebuild on engine #1 with a full bore-align. I have a 1.9L
waterboxer, both engines.
