305k miles is impressive, thank you for the detailed information, I will be doing a CCV replacement next because of what seems to me to be excessive oil consumption. I some say it is normal to burn 1qt every 1000 to 1500 miles but that just seems high to me. also because of the fact I'm not sure when or if it has been replaced before. I just did the intake boot this weekend (dreaded cracked elbow whistling noise). I drive 37 miles to work one way 45mins or so 5 days a week so I'm sure the oil temp is reaching the proper levels and so far she seems to be rock solid running and shifting very nice. looking forward to keeping her on the road for a long time.
