Concerned with mechanicís work on my exhaust
My 2000 Chrysler LHS was making exhaust noise, a mechanic I brought it to said it was the driver side CAT flex pipe.
I bought the new CAT and brought it to another garage who was oil spraying the bottom of the car for me and asked if they could do it. They held the car for 3 days because the V-band clamp bent and they needed a new one from the dealer. Annoying, but whatever, that stuff happens. The mechanic also alerted me that the passenger side flex pipe was rotten too, but the cat was fine.
I picked the car up and it was actually louder than before the driver side CAT was changed and there was a clicking sound coming from the driver side. Thinking it might still have to do with the passenger side flex pipe, I ordered the part and brought the car back.
They held the car for two day to do the repair. When I went to pick it up, they said they had a mishap handling the exhaust and damaged one of my O2 sensors. They said bring it back in a couple days and we will replace it for free.
So now, I am waiting to change the O2 sensor, but there is still a slight ticking from the driver side that lessens when warmed up and when I pop the hood I can smell exhaust fumes around the alternator area. Upon further inspection, as I looked further back I saw that the post-cat driver side O2 sensor wires were all ripped out and gone, which was expected since they have to replace an O2 sensor. However, when they broke this sensor, they were only changing the passenger side flex pipe, how did they end up breaking the driver side O2?
With the noise and exhaust smell, I feel like I might be lucky and that it is just the v-band clamp that is not tightened properly, but another part of me is worried that they were rough when removing and putting in the driver side cat, which broke my O2 sensor and may have in my opinion cracked my manifold. Although the car was loud before, it did not have this ticking and the exhaust fumes were coming out from under the front doors, not the front of the engine compartment.
The car has 104K on it, no rust and is in great shape, but repairing a busted manifold was not in my plans and I feel as if this was their fault if this is the case.
To top it off, the mechanic who did the work was fired at the end of the day when I went to pick the car up.
What would you guys do here? The passenger side is not making any noise and I donít smell any fumes around there.
