My car had engine oil leaking. I took it to a mechanic who advised that the rocker cover gasket replacement will fix this issue. He did not go under the car at any stage to find if there was any other leakage source. I confirmed with again that only this replacement was required and then I proceed with repair. He started taking off cover in front of me. He broke both cam position sensors which were installed next to front coils due to his attempt to forcefully take off cover. He told me they were already broken and therefore they had come off. He quoted me $220 for used sensors and $230 for gasket replacement. He asked for $250 deposit to purchase sensors which I gave (my biggest mistake). I trusted him because he did engine oil service of my car 4 months ago and I found him reliable.
It was already late in the afternoon so I left car with him as he needed to purchase sensors. He rang me next day to confirm the car was ready and everything was ok with it. When I did test drive, I found that the car was misfiring and he claimed that it could be because of sensors installed by him. He recommended to install brand new sensor and also change coil cables which will cost around $700. I told him that he broke my car as I gave car in normal condition with misfire. He argued that it was an old car so repair of one part could lead to failure of other part which I find absurd. After lot of argument he let me took car as I need to think about sensor and I told him I would pay the remaining money when I come to fix misfiring car.
When I checked car after 10 hours next day, the oil leakage was same as before. When I told mechanic he advised that it could be oil sump or rear main seal. Remember he confirmed that the car was perfect and he also did test drive. It is clearly evident that he did not test drive otherwise he would have picked misfiring and he did not bother going under the car after gasket replacement to ensure there was no further leakage.
When I claimed refund of my money as I was left with vibrating car and oil leakage was not fixed, he is going in circles and also demanding $200 for sensor replacement.
I want your advice what I could do to resolve this matter. He broke sensor so I understand he should be liable for this repair. I paid him for oil leakage repair which he understood to be gasket however it was not. The leakage is still there. He is continually sending messages and demanding $200. I feel I have already been robbed of $250 which I admit was my mistake to hand over.
For your reference, I am yet to receive fully itemised Tax Invoice however some investigation reveals that gasket replacement cost $150 including parts however his supplier has made an invoice of $80 just for gasket.
Please assist.
$220 for used cam shaft sensors? Go to another mechanic. Take the loss and move on IMO.
