The latest releases of VAZ "tens" engines included rubber valve seals. The kit consisted of an expander spring and a steel bushing. The manufacturer recommends replacing the oil removal part after the car has run 150 thousand kilometers. Many car owners do this within the walls of a car service center. At the same time, they are completely unaware that in a VAZ 2110, replacing the oil seals of 8 valves can be completely done independently.
The main purpose of the valve stem seal is to seal the joint between the rods. This circumstance ensures that engine oil will not flow into the gap.
The engine will operate efficiently only when the components in the gas distribution mechanism are continuously operating. Engine parts are constantly subject to friction. To minimize their wear, they should be lubricated with oil. But it should not enter the combustion chamber. For this purpose, seals are installed.
When they wear out, the oil will end up in the engine cylinders. This will cause a circumstance to arise in which the oil will begin to burn and form carbon deposits on the walls of various elements. The result will be a drop in compression and the valve will not close tightly.
Design of valve stem seals
Content
The valve stem seal has a simple design consisting of three basic elements:
- base . It is represented by a steel bushing. This is a kind of frame to give strength;
- spring _ Thanks to this element, maximum adherence of the edge of the rubber seal to the valve stem is ensured;
- stuffing box . It is made from rubber or recycled rubber. This element removes excess lubricant.
Replacing valve stem seals without removing the head of a VAZ 2112, 16 valves, step-by-step instructions with photos
Dear friends, today we will tell you in detail and with photographs how to independently replace valve stem seals on VAZ-2112, 2111 and 2112 equipped with a 16-valve engine. The beauty of our story is that in order to replace the oil caps we will not remove the head from the engine, and this is a significant saving of time and labor costs, there is no need to drain the antifreeze, unscrew the manifold, etc.
At the same time, we will do this without using an expensive valve depressurizer, which allows us to do this, but will use a regular valve depressurizer for the VAZ-2110, which can be bought on the car market for 200 rubles. Even before starting work, I recommend purchasing this desiccant, if you have little experience in desiccaning and drying, then take a stock of heels of crackers, we will also need an anaerobic (do not use silicone) sealant, unlike conventional silicone, when in contact with oil, it does not clog the channels but dissolves in it, and also buy a key for tensioning the timing pulley for 50 rubles, since the belt will have to be removed and then set according to the marks. By the way, it wouldn’t hurt to replace the timing belt and rollers at the same time, ideally. If you are ready to do it yourself - no problem, if you lack determination - I can recommend contacting the guys in Minsk to replace the timing belt, they will definitely do it well and inexpensively.
Well, if you’re ready to do everything yourself, then let’s get started. First, remove the plastic cover from the engine and gain access to the “intake manifold”
