If the hose is starting to collapse from your oil breather then you should
replace it with either oil resistant hose or with heater hose (heater hose
will last about 2-3 years, oil resistant is better but harder to find).
There are, I think is was, valves or something in the oil breather that
helps it to maintain lower air pollution, etc. to be in tune with EPA
regulations, but I can't remember the details.   Check the archives because
I just read some info. on what is inside of the oil breather from the
mailing list.  Lost power could be the result of a variety of problems, you
need to do some diagnostics.  Could be vanagon syndrome, could be fuel
injection problems, could be oxygen sensor problems, etc.  I'm having some
similar problems right now, and I'm about to clean out my fuel injectors to
see if that remedies the problem - trial and error.  Hope this helps.
