Cylinder Head: Notes
Special tools and workshop equipment required
- Drip tray V.A.G 1306 or drip tray for workshop craneVAS 6208
- Torque wrench V.A.G 1331
- Torque wrench V.A.G 1332
- Diesel extractor VAS 5226 or hand vacuum pump VAS 6213 or hand vacuum pump V.A.G 1390 and
- Hand vacuum pump reservoir V.A.G 1390/1
- Bracket T10014 (only vehicles through 05.05)
- Engine support bridge 10 - 222 A with adapter 10 - 222 A/13 (only vehicles through 05.05)
When using an exchanged cylinder head with camshaft installed, the contact surfaces between the lifters and cam lobes must be lubricated before installing the cylinder head cover.
The plastic protectors installed to protect the open valves must only be removed immediately before fitting the cylinder head.
When cylinder head is replaced, all coolant must also be replaced.
Cylinder heads with cracks between the valve seats can continue to be used without reducing service life, as long as the tears have a width of max. 0.5 mm.
Do not mill the valve seats in the cylinder head; only grinding of the valves is permissible.
After installing the camshafts, the engine may not be started for approximately 30 minutes. The hydraulic equalization elements must seat themselves (otherwise the valves will crash into the pistons).
After working on the valvetrain and lifters, carefully rotate the crankshaft by hand at least 2 full revolutions before starting to be sure that valves do not strike the pistons.
Always replace gaskets and seals.
All cable ties which are opened or cut open when removing cylinder head, must be replaced in the same position when installing cylinder head.
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
- Route lines of all types (e.g. for fuel, hydraulic, coolant and refrigerant, brake fluid, vacuum) and electrical wiring so that the original path is followed.
- Ensure sufficient clearance to all moving or hot components.
