The valve is abnormal, how does the engine burn oil?

1, the oil leakage of the valve cover is caused by improper installation of the valve cover gasket or poor quality of the valve cover gasket, and has nothing to do with abnormal engine noise.

2. "Da, Da" noise from the upper part of the engine is generally caused by excessive valve clearance. It can be solved by replacing a set of valve hydraulic tappets (by the way, the valve oil seal can be better, which costs tens of dollars).

3. As long as the valve oil seal is in good condition (not aging), the clearance between the valve and the valve guide tube conforms to the manufacturer's regulations, and the clearance between the piston, piston ring and cylinder conforms to the manufacturer's regulations, the oil will basically not be burned out, and the influence of other places on the oil burning out is much less likely.
