An engine overhaul today is undoubtedly an event for the wealthy, no matter what car you have. It is expensive even on the old Zhiguli. But how else, if the engine should already stop at age and condition? It turns out that there is a tool and it was developed in the USSR. Details – on the portal “AvtoVzglyad”
Years take their toll and sooner or later every combustion engine starts to grumble. And the worse he was served, the sooner this hour will come. Judging by the condition of the whole car, our design Mitsubishi Lancer knew specialized craftsmen only in his youth, and the second owner did not spoil him with high-quality spare parts and professional repairmen. Served whenever and wherever they could, then fully locked in the garage for years. Of course, such exploitation cannot remain without consequences. As a result, the engine, the most expensive part of a car, began to emit distress signals: diesel, hard to start, ticking and tinkling. Meanwhile, Mitsubishi is not the cheapest brand to maintain, and now it is just expensive. Even if you do the engine overhaul yourself, an intelligent set of necessary spare parts will cost 100,000-120,000 rubles. And go find them for such an old car.
However, the 4g63 engine is known for its reliability and unpretentiousness, so the general editorial decision was to try fate and give it a second chance: to use the old Soviet technology, which made it possible to significantly, by 50 or more thousand kilometers, postpone operation.
The principle is simple and, by the way, is used today on new German motorcycles: cermet. Simply put, a durable ceramic layer is applied to friction pairs, for example a piston and a cylinder, which significantly improves sliding and helps protect iron from further increased wear. It is curious that today this is already done directly in the car factory and has been used on German engines from the beginning, replacing a cast iron sleeve in an aluminum block. But they came up with a method in our USSR, where they have been practicing applying ceramics to iron parts since 1982. A ready-made solution for a broad market, as it were, saw the light of day in 1991, but remained “under the curtain” for a long time. But then the development fell into the right hands, was improved and refined many times, the composition of more than ten generations, and presented to the public.
Meet Forsan from Nanoprom. Initially, the technology was applied and tested on expensive industrial equipment and heavy equipment – Kamatsu, BelAZ and many others – but gradually it came to the most ordinary, civilian vehicles. Let’s try and maybe this way we can avoid a shot at our Lancer?
To begin with, it is worth noting that Forsan is not an additive at all, it does not mix with engine oil and does not affect it, therefore it does not cause precipitation. Here it is not chemistry that comes into play, but physics, according to the laws of which the process of forming cermets takes place. Second, no drug in the world can build pistons, straighten connecting rods, rejuvenate valves, or regenerate valve stem seals: these miracles only happen through replacement. Ah and ah. But many signs of use (read, wear) of the engine can and should be removed with the help of this home remedy. By the way, you can keep it in a wear-free condition for quite a long time, carry out an operation every 50,000 km, until fatigue processes take over and the axles and connecting rods begin to break, to which the car usually does not even live .
In total, there are two types of Forsan from the company Nanoprom: for self-treatment of the engine and for professional, which is done at certified service stations. The pro version is more expensive, more complicated, but also more functional, so in our case we prefer it. At the same time, the technology does not require disassembly of units and the composition is introduced through standard oil filling holes. The engine is running, so we immediately go in a big circle – so the chance of success is higher.
First of all, we measure the compression: if the rings fell apart or lay, and only the stumps remained from the valves, then it is too late to pour Forsan. However, at the first stage we are lucky, the engine shows decent compression in all “boilers”, so we start processing. We also know that for 1000 km our engine “misuses” about 250 grams of oil and, to top it off, a hundred liters of gasoline. It’s in the city cycle. At the same time, the motor does not overheat, the cooling works on time, does not rattle and does not play tricks. We solved the oil leak by replacing the crankcase, drain and fill plugs, camshaft seals and hydraulic chain tensioner. Gaskets do not leak, including gaskets for candle tubes. There is no smoke, the vibrations are within acceptable range for a used car from the 1990s. Everything is ready for the experiment.
We warm up the engine to approximately operating temperature, after which we mix the composition, which is presented in syringes, in a special container with the oil currently being used (the retail version is already completely ready for use). It takes about seventy milliliters of lubricant – we certainly will not pour it, no seals will be squeezed out. After that, you should let the engine idle for an hour.
Then you have to run in the engine as if it were new: a hundred kilometers in a quiet run-in mode, then another nine hundred (1000 km in total), gradually increasing the speed and putting it into normal operation. After treatment with Forsan, we will measure the compression again and expect the results of this product.
Equally curious and a little uncomfortable: what if it were really possible to save countless engines, with which we were familiar by the nature of our work in motoring journalism, by delaying their shot for a long time – the alleged effect of the drug is more than 50,000 km, after which the ceramics are erased ?
Is it really that simple, in the yard, that a car owner can get nearly two years of deferral from a major investment? We will receive answers to these and many other questions shortly.
