How to solve the problem of burning engine oil in Chevrolet copaci

Reasons and solutions for burning engine oil in Chevrolet copaci: 1. The exhaust gas recirculation valve is damaged, and the oil exhaust gas enters the combustion chamber, causing the oil to burn. Methods: Remove the empty intake pipe and check whether there is obvious oil pollution near the EGR valve. Solution: Repair or replace the exhaust gas recirculation valve. 2. The gap between the engine valve and the valve guide tube is too large or the valve oil seal is aging and not tightly sealed, which causes the oil to enter the combustion chamber from the valve position and cause the oil to burn. Inspection method: drive &; Rarr open the oil filler cap. Check whether there is blue gas spouting, and if there is, whether there is air leakage; Not so good. Solution: Replace the valve, valve oil seal and valve guide.

3. The engine cylinder gasket burns through, causing the oil to leak from the oil circuit to the combustion chamber, thus burning out the oil. Methods: Remove the spark plug &; Rarr checks the cylinder pressure. If the air pressure of two adjacent cylinders is similar and the air pressure is lower than the standard value, gas channeling will occur in the cylinders, which may cause oil leakage. Solution: Replace the cylinder gasket. 4. The clearance between piston, piston ring and cylinder wall is too large, which causes the oil to enter the combustion chamber for combustion. Judgment method: drive &; Rarr pulls out the dipstick and observes whether there is blue gas spouting from the dipstick. Yes, burn engine oil; No, don't burn oil. Solution: engine maintenance, replacement of pistons, piston rings, cylinder liners, etc.
