1 /5 Albert Hamalian: A few years ago, I brought my 84 Prelude in to replace a heater hose because it was in a tight spot. When I came to pick it up, the short, chubby guy (owner- I think) told me that for some reason, its running rough and when I started it...indeed it was. I suspected foul play from then on because Im aware of such practices. That is one reason I always work on my own vehicles, another reason would be, cost. I had the part (heater hose) so I paid the $100 of labor, just for the convenience.
I took it home and began inspecting -primarily the emission hoses. After a few minutes, I noticed a clean spot on a hose port which looked as though the hose has been removed. The only nearby emission hose long enough to make this ports connection was attached to a diaphragm close by. I searched around the diaphragm and found a disconnected hose tucked under the diaphragm. He disconnected the hose from the dust free port-that I first noticed- and hooked it to the diaphragm while tucking the diaphragm hose out of sight. When I made the necessary corrections... the car was fine and shortly thereafter, passed smog.
I want to also point out that the heater hose was on the other side of the car and that no access would be provided from the area of my discoveries. The port ITSELF with the missing hose was clear across the other side next to the fender. Been working on my vehicles and reading service manuals since my first car and there is no way it was accidental.
I didnt bother to call him to complain. I was just glad I found the problem. These type of malpractice exists folks. This incident reminded me of a 20/20 OR 60 minutes undercover report my father and I were watching back in the early 80s when I was about 12 years. I never forgot it. Use caution when going to a mechanic. Bring someone with you if youre not savvy.
