So I have a manual 05 EX with about 210k on it. Had it for a little over a year and it's been great, and I hope to keep breathing life into her for many years to come. Right now I'm having trouble with a misfire that was caused by tight exhaust valves that have since been returned to factory specs. My mechanic told me to drive it a little longer to see if it got better or not. He mentioned it could be a burnt valve or just excessive carbon build up. I also asked what he would charge in case I did need a valve replacement and he rough quoted me $1200-1500 for a valve replacement. I don't have that kind of money sitting around, so I'm looking to do this myself. I was hoping that I could find some information about removing the head and all the torque specs required for the reinstall but haven't really been able to find much. I don't have a service manual, and I'd like to save as much money as possible to get my baby girl running smoothly again. So if anyone can help me find a thread that I'm missing or give me some information about the whole process of a valve replacement it would be greatly appreciated. Thanks.
