I hired a service to change the head gasket, because my car was boiling hot. The mechanic told me that he would also have to change the Timing chain for the service to be good. I agreed, then he invented that he also needed to change the carter, I agreed. In the end I spent 2,000 pounds, the car was there for 3 weeks and when it came back it came back worse than it was before, as the problem persisted and still came back with some loose parts, causing the alternator belt to come loose, causing me more expenses. I strongly recommend that you do not use this service. I wish I had read these reviews sooner. This app does not give you any help, they say that the Mechanic is to blame, and that mechanic will be removed from the system. The mechanic simply ignores your complaints, and you take the loss.
