Is the Subaru H6 3.0 a good engine

*Based on what I've seen at the shop* - the H6 is much more reliable than the 2.5 .. Just don't let that engine overheat and it should be fine. It has a timing chain instead of a belt, which I think is a plus - no inherent head gasket problems like the 4 cylinders - that I have seen. I personally do not like Subaru vehicles - because of the head gasket issues on the 4 cylinder engines, however plenty people obviously love em ... Then again, I guess I see more problems with them than most 'individual owners' would ever see.
