If you find traces of oil leakage through the camshaft seals, first check to see if the crankcase ventilation system is clogged and if its hoses are pinched, and if necessary, repair the faults. If the oil leak continues, replace the seals, otherwise you will be faced with costly cylinder head repairs. Oil getting on the timing belt (gas distribution mechanism) will corrode the belt. The belt will break and bend the valves on the 16-valve Lada Priora engine. Do you need this? Hence the conclusion - no matter how well the engine works, smoothly and without noise. A technical inspection of the engine compartment of a Lada Priora is regularly required for leaks of oil, brake fluid, coolant, etc.
To replace the camshaft oil seal you will need:
Adjust the tension of the timing belt and tension roller, and the generator drive belt.
What else can I add here? Don’t fall for a counterfeit, because now anyone is too lazy to stamp oil seals in garages and utility rooms. Buy from trusted sellers and branded stores. Do not buy so-called silicone seals. Under this name, there is a widespread counterfeit of oil seals; such oil seals are not oil-resistant and spread out in literally a week and will cause quite a lot of trouble. It’s better to buy factory seals (made in Balakovo).
I want to share a little experience, but the photo will mostly not be mine, because I spent two days digging, was cold and very angry, and had no time for photos. The other day I noticed that the plastic timing belt cover in the front middle from the top edge to the crankshaft began to become covered with oil. I unscrewed the casing and found the greatest amount of oil in the area of the intake camshaft pulley. I bought two oil seals in the store (made in Balakovo, that’s what the seller said
