15 Cylinder Head, VALVETRAIN: VALVETRAIN: Notes

NOTE:

Cylinder heads with cracks between the valve seats, or between the valve seat and the spark plug threads, can continue to be used without reducing the service life, as long as the cracks have a width of max. 0.3 mm, or only the first 4 threads of the spark plug threads are cracked.

After installing new hydraulic valve lifters, the engine may not be started for approximately 30 minutes. Otherwise the valves will impact the pistons.

Turn over the engine carefully at least two turns after working on the valvetrain. This assures the valve do not strike the piston when starting the engine.
