Yes, you overpaid. I see that this is not your first post, and you have looked for advice, but it appears that you did not heed to some of it. Chalk it up as a lesson learned. To say the shop burned you, that is a tough call. To do the job, they had to peel the front of the motor apart, change the oil and the coolant. Maybe they looked at the oil after it came out, most likely this went right into a catch basin and was never looked at. If this was your daily driver and the work needed to be done, i could see paying more than usual, but not that high. Please don't tell me someone you know from this board recommended the shop. Odds are the shop thought they were doing a good job, and it might be true on the imports that they work on, but always do your research. Working on these trucks is easier than making a cake, and if you don't know something someone has already done it and can give you the rights and wrongs.
