It cost me $165 for a new OEM chain, 4 OEM guides and an OEM guide rail - shipped. The whole thing took about 8 hours, but that's because I spent 75% of my time cleaning off 24 years of engine gunk (my PS pump went from black to silver).

There's a very good DIY article on rolling in a new chain (if your guides aren't dark brown). If all I had to do was the chain, it probably would've taken 20 minutes, tops - you only have to remove 1 valve cover. I decided to replace all 3 head-mounted guides and the guide rail as well, which adds a bit of time.


Oh, and yes, since this is an interference engine, it is definately worth replacing unless you know for a fact it's been replaced within the last 100K miles.
