“Digging coal” has become a necessary maintenance item for the direct injection engine in the cylinder, just like regular oil change, and it needs to be cleaned every 60,000 kilometers. The owner said that recently the engine light is always on and the cold car shakes are serious. More than 10,000 kilometers, it is almost time to dig coal. The specific operation should be well understood. Today, using this car to talk about the EA888 engine, how to distinguish the first, second and third generations.
This Octavia is a 1.8T EA888 engine. After several years of use, many problems have gradually surfaced. The first and second generations have burned oil, the valve rocker roller bearings are easily broken, and the tensioner pusher gears are too worn. , Resulting in timing jump teeth. The chain guide is too short to keep the chain in close contact with the gear. There are too many transmission accessories, and the timing chain is prolonged after a long time.
EA888 engine air intake pipe is in front of the engine, it is very easy to disassemble. This engine belongs to the second generation. The earliest was listed in 2009 (2.0T).
The first generation was launched in 2006 (2.0T). Installed models: Magotan 1.8T (the earliest 07 models), Magotan 2.0T (the earliest 08 models) Octavia 1.8T (the earliest 07 models) Octavia 2.0T (the earliest 10 models). The difference between the first and second generation is not big. Except for the improvement of the oil and gas separation device, the others remain unchanged. The appearance is not easy to distinguish, the dipstick or oil filler cap is slightly different.
The difference between the second and third generations can be distinguished from the appearance. The positions of the oil filler ports are different. The first and second generations are on the left side of the engine. The third generation is on the left side of the engine. The three-generation engine shroud is all black.
The third generation: listed in 2011 (1.8T) / listed in 2012 (2.0T) / started domestic production in 2013, there are many improvements in the third generation.
1: Three generations of cylinders become thinner 0.5MM
2: Cylinder block water channel changes
3: There are 4 additional screw holes on the spindle bush for directly fixing the oil pan.
4: 8 weights on the crankshaft become 4 weights.
5: Tensioner becomes spiral
6: All of the upper and right sides of the chain guide are lengthened.
7: 5 pieces of timing chain become 4 pieces, but the thickness is thicker than before.
8: Oil filter changed from iron shell filter to paper filter
9: The oil and gas separation device used to be an independent cyclone oil and gas separation in the outside. At this level, the third generation uses a built-in oil and gas separation device, and there is also a secondary filtration.
10: The second generation of the engine balance shaft is straight, and the third generation is designed with eccentricity and is not straight.
