Jose was able to determine that my Blazer's issue WAS related to my engine [as my original mechanic suspected]. That means that the initial mechanic, whom I scheduled through "Your Mechanic," misdiagnosed. He insisted it was the A/C compressor, leaving me hopeful [and paying for a second inspection for work that won't be economical for me to complete].
Jose examined my Blazer like a medical clinician would examine a person. He checked various areas under the hood, using a tool to listen & feel with, while the engine was running. He also had me do the same, so I could understand how he was able to quickly rule out where the problem WASN'T coming from. He determined it was coming from the back of the engine [what I was afraid of, from the start].
So, basically, the first inspection was a bust....which didn't leave me with much confidence in my pre-purchase inspection of the Subaru, done by the same mechanic. It's a shame, because I found him likable and he seemed honest. But I don't feel encouraged to use him again.
Additionally, in discussing my friend's Subaru, that I am currently driving, I learned, from Jose, that the timing belt should be given a greater priority status than either of us were giving it. I will have to check with my friend, to be certain; but I will likely want to schedule maintenance with Jose soon. I work nights, but I could schedule in the morning....better yet, on a Thursday or Friday. But, again, I will wait have to wait for approval from the car's true owner [even though I was intending to pay for it, myself].
