in the cylinder head bore.
NOTE: the housing and tensioning piston of the chain tensioner are
compression molded. If the two parts cannot be separated, the chain
tensioner must be replaced.
– Apply the chain tensioner bolt and new sealing washer to the chain
tensioner element without compressing the spring.
– Measure the distance

between the sealing washer and the cylinder
head.
The measured value should be between 6 mm and 11 mm. If the value
is lower, the tensioning rail could be worn or the timing chain
excessively elongated. If it is higher, the engine was turned to TDC
against the running direction.

and tighten to 20 Nm.
