Lavida valve oil seal is gold, row or in?

What everyone cares about is "is the LaVida valve oil seal gold in the row or in?" Let me explain something to you:

Air intake and exhaust are not considered.

Lavida valve oil seal does not distinguish between intake and exhaust. Oil leakage will occur when the valve oil seal is aging; Oil leakage from valve oil seal will accelerate oil loss; Blue smoke from the back of the exhaust pipe; It will cause oil to leak into the cylinder, thus forming the phenomenon of "burning oil". The removal method of the valve oil seal is as follows:

1. Remove the camshaft and hydraulic tappet and store them face down. Please note that tappets are not interchangeable during operation. Remove the spark plug with a spark plug wrench, adjust the piston of the corresponding cylinder to the top dead center, and screw the pressure hose into the threaded hole of the spark plug;

2. Install the spring compression tool on the cylinder head with bolts. Adjust the relevant valves to the correct position, and then connect the pressure hose to the air compressor (air pressure is at least 600kpa). Press down the valve spring with the threaded mandrel and thrust piece, and remove the spring;

3. Tap valve spring retainer and remove the valve lock block. Pull out the valve stem oil seal with a tool.

Do not distinguish between intake and exhaust.
