The collapse of the GRM in Lachetti in most cases leads to the bent valves and, as a consequence, their replacement, and sometimes to the need to replace the cylinder head.
According to the passport of the model, it is necessary to change the belt of the gas distribution mechanism after every 60,000 km of mileage. However, the specialists and experienced Lachet owners recommend replacing more often-after every 45,000-50,000 kilometers. Along with the belt, as a rule, the roller skates and the water are changing.
It is also recommended that you change the pap. Its resource is larger than the GRM-belt, but not much-about 70,000 kilometers of mileage. Therefore, in order not to pay for the same work, pump can be replaced with belts and rollers.
