Symptom | Cause of Failure | Remedy |
A knock at the start of the cold engine, which then stops | Normal | Knock ceases as soon as the oil pressure reaches normal values |
Knock for a long time when starting the engine, do not work for 48 hours or more | Oil leak from the high-pressure chamber and pushers getting air into it | Knocking must stop within 15 minutes at the engine speed of 2000-3000 min -1 |
Standing at the first sound of the engine is started after the assembly of the cylinder head | Insufficient supply of oil in the oil pipe of the cylinder head | To ensure the normal flow of the oil in the oil pipe of the cylinder head |
Standing knock while the engine after a long scroll wheel or starter | Oil leak from the high-pressure chamber and pushers getting air into it | To ensure the normal flow of oil |
Standing knock when the engine after replacement of pushers | Insufficient supply of oil pushers | To ensure the normal flow of oil |
Standing knock at idle when the engine is running at high engine speed | Engine oil level is above or below the norm
Contact with a large amount of air in the oil during engine operation with high engine speed Deterioration of oil | Check the oil level and if necessary to restore it to a normal Check lubrication system
Check the quality of the oil |
A knock at the engine for 15 minutes or more | Low oil pressure
Problem pushers | Check pressure and oil flow at all engine components Remove the cylinder head cover and check whether the pistons move pushers when pressed with a finger. If the plunger is moved to replace the pusher |
