How do you know if the gasket under the cylinder head is punctured? What symptoms indicate this and how to be sure of this?
Symptoms:
- The engine gets very hot
- the engine blower fan turns on much more often
- it is not clear where the antifreeze goes
- on a hot engine, antifreeze can be expelled through the expansion tank plug
- when starting the engine in the morning, the engine undergoes some time
- as a rule, one spark plug has black carbon deposits, while if the spark plug is replaced, then after a while the engine is running, the spark plug in the same cylinder will again have black carbon deposits
- the radiator pipes are inflated
- the interior stove stops blowing hot air
- antifreeze flows through all possible connections
- white smoke from the muffler
How to check:
- unscrew the candles and check them for the color of carbon deposits
- supply compressed air from the compressor to the cylinder, first in this cylinder raise the piston to TDC and close the valves
If the gasket is punctured, air bubbles will appear in the expansion tank or the amount of antifreeze in the tank will increase.
