service AUDI A4 1998 B5 / 1.G APB Engine Valve Gear Service Workshop Manual

15-1


Valve gear, servicing

Notes:

Cylinder heads which have cracks between the
valve seats or between valve seat inserts and
the spark plug thread can be used further
without reducing service life, provided the
cracks do not exceed a maximum of 0.3 mm in
width, or when no more than the first 4 turns of
the spark plug threads are cracked.
After installing new lifters the engine must not
be started for about 30 minutes (otherwise
valves will strike pistons). Turn crankshaft two
complete revolutions before starting.
Carefully apply a small amount of sealant D 454
300 A2 at the four end points of the sealing
surfaces on the cylinder head, using a small
screwdriver Fig. 1
