Almost every owner of the Lada car has encountered a leak of oil from under the valve cover. This is certainly not a critical moment, but attention should still be paid, because the oil falls on the collector, injectors and, in general, in combination with dust, pollutes the engine. Replacement of the standard gasket with silicone is the optimal solution. With proper performance of work, the gasket will create a tight connection through which the oil will no longer ooze. Also to the attention of the owners of VAZ 2123, in addition to the gasket, oil can ooze from under the studs of the intake manifold,
it is necessary to unscrew the studs and treat them with a sealant. It may be necessary to treat the seam of the oil neck of the valve cover with cold welding (oil also oozes from there).
