All,
Unfortunately I found out today how they fail. The pump seized when I
was going 60 and it tried to turn my belt to liquid rubber. Lots of
blue smoke for 5 seconds and then the belt snapped. I'm getting a new
pump. I'm sure the old one is mostly trashed. For those of you that
have the new style pump I'm told you CAN add oil even though Peugeot
says it requires no service. That could save you hundreds of $$. Mine
failed at 90k and there has never ever been even a trace of oil on the
outside that would indicate a leak.
