Owners of orange engines who believe that “Varnish is normal and does no harm at all, dude, you’re talking nonsense!” Below is an example of a “Typical varnish engine”…
Enter in Yandex Images – Replacing the valve cover gasket Lancer and get a varnish engine right away :)))
I take a photo of my engine from the bc data vietnam account (at that time I hadn’t even wash it with dimexide, the head was clean, but the bottom was shitty – in my case italy numbers was just COKE on the rings, thank the gods – judging by the head – it did without varnish) :))
A clean head doesn’t ask for powder 🙂
Well, guys, this is not normal – Varnish deposits are dangerous for piston rings and they coke them up nicely! Below is an excerpt from the article (you can read it there, he also has good photo proofs) Proofs
» As far as I know, 15-20 years ago such a problem benefits of solar panel kits not exist in principle. Yes, the engines of special economists were cover with a certain layer of soot, which fell out of dead oil and oxidiz oil in the form of a viscous liquid, which was quite easily wash off with ordinary diesel fuel without the use of various chemicals like DMSO. But they had practically no wear and did not contain hard shoe polish, varnish, stone deposits, and no one had ever heard of “marmalade” from oil. But the Bright Future has come.
Oil manufacturers were inventing ways to make lubricants from the cheapest raw materials (useless waste – asphalt fractions of oil). And then a way was found – the implementation of “hydrocracking” technology began everywhere. Then it was introduc as the 3rd basic group of oils. And since then we have been looking for the ideal oil, intervals and modes at which the oil does not die, does not wear out and does not dirty the engine. And most importantly – does not coke or roll rings into the asphalt, which lose mobility.
The peculiarity of hydrocracking is that it is very unstable
At low temperatures, sludge begins to form – combustion products of our “high-quality fuel” and oil oxidation products fall out of the oil (pay attention to the windshield cover, sump and valve cover – they are all terrible at high mileage), hydrocracking does not hold them in itself very well, even with the most sophisticat tolerances, and at high temperatures, a polymer thickener falls out of the oil in the form of yellow varnish under the valve cover, on the rings, forming a hard, very durable and almost indelible carbon deposit. As practice has shown, even 10% dimethyl sulfoxide in oil removes such deposits extremely poorly. And these deposits are no longer remov by any oils with short intervals … ”
Notice the color of the deposits? Remember the color of your engine waste? Looks similar, doesn’t it?
If you dig a little deeper on this topic, you can go to the Oil Club forum and find this oil club article about engine deposits.
At the moment, we are only interest in “VARNISH”, so I am copying the insert from the article about the varnish itself:
Varnish is a product of the change (oxidation) of thin oil films that spread and cover the parts of the cylinder-piston group (CPG) of the engine under the influence of high temperatures.
The greatest harm to the internal
Combustion engine is caus by varnish formation in the piston ring area, causing processes of their coking (deposition with loss of mobility).
Varnish, deposit on the piston surfaces in contact with oil, disrupts proper heat transfer through the piston, worsens heat removal from it.
The thermal state of the engine parts that come into contact with engine oil has a decisive influence on the formation of carbon deposits, varnishes and siments on the surfaces. In turn, the design features of the engines, their operating conditions, operating modes, etc. determine the thermal state of the engines and thus influence the processes of deposit formation.
