I tried to adjust the valves on my 300D over the weekend, but it was only an exercise in futility. I had the two 14mm wrenches bent properly, but holding the large collar nut in place was virtually impossible. What does one use for this? A crescent wrench is out of the question, and channel-locks get just close enough to make me want to punch my head in utter frustration. I considered removing the fuel injectors, but declined for lack of time. Do I need to order a special wrench for this?
I found that most every exhaust valve was too tight, but the intakes were fine.
