I had cam belt,s kit replaced on range rover sport 2006 on the 02/08/2018 by a garage that is not a L.R.R garage on the 08/01/2019 my car would not star.It was lucky I was at a L.R.R garage for a car wash at the that time they found it was the camshaft sensor was cut in two they said this would not just happen and ask if I had work done on my engine I said I had the belt,s done. They had a look camshaft belt and found bolts in passenger side camshaft pulley were loose and one had come out and ripped a chunk out of the belt cut the sensor and damaged one of the pulley,s.I was told this was caused by the bolts not being tightend properly is this correct,The garage that done the work in the first place said if they had not tightend the bolts properly they would expect it have failed within a week not 5 months and one week later can you please advise me whose is correct in this matter
