My vehicle had too much oil and it was burning it through the exhaust, throwing out an excessive amount of black smoke. The mechanic told me the rings needed to be replaced; but he changed them and now the car does not even start. He is now telling me that this happens because the tappets need to discharged, but I really do not know whether to believe him or not. What do you think?

Cars hard to start. Also exhaust fumes sell like the dpf constantly on regen its not I've checked smokes like hell in 4th to 6th with high revs checked my torsion valves 0.30 and fuel at 0.9lh what I personally think should be 0.4ish lph bought the henz manual absolutely no mention of it

Three years ago, the engine indicator appeared on the dashboard and, when taking the car to the agency, I was told the turbo had broken down. However, it was so expensive I did not replace it, and actually the turbo was working. The car jerked and pulled and the indicator appeared every now and then, causing a significant power loss. I went to other mechanics who told me the problem was an excess of pressure on the turbo and decided to cancel the EGR. The light continued appearing and, after a year, I returned to the agency. This time, they cleaned the turbos properly and connected the EGR and the problem was solved. I was so disappointed they hadn't done exactly that a year before. I wanted to share my experience in case someone has my same problem.

A year ago, the front right bearing needed to be replaced because it was damaged. Three months ago, one day the car could not be opened and it was because the battery had broken down. This morning, I was going to work when, suddenly, the engine failure indicator turned on and the emergency mode is set. I have been told that the EGR valve is damaged but it is quite expensive to replace it. On Monday, I'm taking the vehicle to the agency to see what is wrong with it that so many failures appeared in only one year.
