Gave my 2003 V70 NA to my sister for a few weeks while her car was being repaired. She called in a panic that it started making noise and the check engine went on. Had it towed to a kind of recommended service station near her and here is the bad news.

It was/is a rod bearing and the mechanic feels that it the bottom end was that starved for oil there is most likely some top (cam, etc) damage that might show up latter. Recommends not rebuilding this engines (too costly) but getting a used engine and installing, with new timing belt (and related parts) new clutch and throw out bearing. This will have some type of warranty (12 months) and all this will be about 4K. What do you guys think?

Would I need to get the same year 2003, engine? This is a NA engine, can I get a turbo installed? The car itself is in great shape and I'm kinda debating on what to do.
