In the operation of the VAZ-21 123 coupe, I was faced with failure, with the successful renovation of which I want to share. I think that this advice is a good idea to know the owners of the WHA with the front drive, and especially the WHA - 21 123 coupe. On a cold winter day, having got the car and discovered that I had not extinguished the oil pressure light emergency. Thinking that just a cold oil can quickly begin to circulate, I continued to maintain the average engine speed, in the hope that light bulb goes off. However, rather than extinguish, the light continued to burn bright red, and the engine began to work with the characteristic iron thud. Stop the engine, I was sure that he brought him down.
Calling friends on his cell, I got some advice from experienced car owners. Picture emerges about this - knock on joints due to lack of oil pressure, which has ceased to flow to the valves. Reservation, that my engine VAZ -21 123 coupe with a sixteen-valve (which is somewhere in their design and sitting of these ill-fated expansion, I have not seen). It remained to find out why there was no pressure! The first thing that came to mind - it is certainly frost, because the pressure was yesterday. I decided to warm the crankcase means at hand, that is, the heating plate. Light bulb goes off the pressure as soon as I started the engine warmed up with a sump, and just a few seconds lost in the sound of metal valves.
Was relieved from the heart! Once in my spare time I removed the crankcase, it was discovered that the bottom of the housing was a mixture of different villi, which scored maslopriemnik. Point is that between the crankcase and maslopriemnikom very small distance, which proved to be even smaller due to the fact that he was deformed casing. Deformation occurred probably in the crankcase while there was no armor, and had to go on track - for mushrooms, or on vacation in the woods. Replacing the crankcase, I made to a conclusion - in time to change the oil, not to save on washing and not go without armor, substituting crankcase shock bumps roads!
