Viltor

Good evening everyone, I own a civic VTI in Portugal, and I noticed the power steering fluid were getting low. My mechanic told me my power steering rack is leaking and I need a new one, the problem is in Portugal a power steering rack is very expensive, its like 600€+. Anyone has an idea if I really need to change my power steering rack or there is something that I can do to fix it ? Wich models ate compatible to swap on my MB6 ? Thanks
