Valve seals
Removal and installation
Removal
1. Remove the camshafts. See above.
2. Remove the valve tappets. See above.
3. Rotate the crankshaft until the piston of the cylinder on which the oil seal needs to be removed is at TDC. This will prevent the valve from falling into the cylinder.
Attention. When turning the crankshaft, do not pinch the timing chain with the front cover.
4. Take out the crackers.
- Compress the valve spring using the attachment tool and adapter (special tool KV10H6200) (A). Remove the crackers using a finger magnet.
Attention. When carrying out work, do not damage the holes for the valve tappets.
5. Remove the valve spring retainer and valve spring.
Attention. Do not remove the valve spring seat from the valve spring.
6. Remove the valve seal using a puller (special tool).
Installation
1. Apply fresh engine oil to the new valve seal and sealing lip.
2. Press in the valve seal using a drift (special tool) up to height «N», as shown in the figure on the next page.
Height «N»: 11.8-12.4 mm.
3. After this operation, installation is performed in the reverse order of removal.
