I have answered this question in this forum several times and I will answer again the same way. The only answer to your question that has any meaning comes from the person willing to do the job. Count on $300 or so in parts from Subaru, less if you want to use after-market. I have seen labor prices from around $600 to well over $2000. Same answer goes for the price on any other service.
Yes.

YES! Replace the head gasket or destroy the engine if you continue to drive it.

Yes you can!

Just had it done on my 1998 Venture - It cost about 900.00
Likely a head gasket issue, especially if this is a 2.5L DOHC. The head gaskets on the 1998 Phase 1 Subaru 2.5L DOHC engines have a high failure rate.
