P0017 in Engine & Transmission Posted November 20, 2019 Britprius, I found that one of the black guides had broken and one had cracks in it. I've had this car from almost new, so I know it's now been abused. The plunger that takes up the slack was only just touching the guide. So glad I did this much. Mostly rebuilt now, just waiting on the pipe that has a 2 week delivery from Japan.
