According to the recommendations of the factory, the alternator belt should be replaced after 15 thousand km

Usually, the camshaft oil seal is replaced when the engine is being repaired and when oil is leaking.

Leaking oil, splashing, falls on the timing belt, which deteriorates as a result

We remove the oil receiver when repairing the engine or when the oil receiver mesh is clogged, and the engine is starved of oil

If there are signs of oil leakage through the camshaft seals, first check if the crankcase ventilation system is clogged and if its hoses are pinched, repair if necessary
