Intake valve cleaning carbon deposit & replacing intake manifold triangle plate
JasonEllen 
11 Some time ago, I did a cylinder carbon deposit cleaning, and the fuel consumption was significantly reduced during the same journey, so I planned to do another intake valve carbon deposit cleaning. I was going to do it last week, but the test found that the triangular plate of the intake manifold was faulty. So I bought an intake manifold triangular plate maintenance kit from the Internet (it is recommended to buy a maintenance kit, not just the triangular plate), and went to do it on the weekend. Clean the carbon deposits on the intake valve and replace the triangular plate by the way. If it is just to replace the triangular plate, the disassembly cost will cost 300 to 500 yuan. Now replace the triangular plate for free. I feel like I made a lot of money, huh
After opening and disassembling, everyone is familiar with the 272 engine.
The air flow meter has also been removed. Why are there oil stains? Is this normal? The servant said it was normal
The intake manifold was also removed. It was very dirty, and the triangular plate was obviously broken.
Judging from the fracture surface, the broken triangular plate should have just broken. Did it break after cleaning the cylinder carbon deposit last time? Yan Ban is right, don’t mess around if you have nothing to do, ha.
In addition, when tightening the right screw, half of the screw broke in the cylinder block.

The person from the repair shop called someone who specialized in taking screws. It was 150 yuan for each screw, which was expensive enough.
This is the steel triangle plate in the maintenance kit. Mom said that you don’t have to be afraid of breaking anymore…
Effect after installation. There are also some parts in the maintenance kit, including the three air bags, that are also installed.
There is some carbon deposition on the intake valve, but it is not particularly serious.
It is common to use this machine to clean walnut sand.
Spray walnut sand, suck it out, and wash it repeatedly.
It was very clean after cleaning and no photos were taken.
