REMARKS :
#
- camshafts for use in X18XEV-2.0L-2.2L long block 'ecotec' engines
#
- valve clearance is to be adjusted using mechanical lash caps
-
please make sure that the lash cap does not touch the valve locks !
#
FOR COMPETITION APPLICATIONS ONLY. Following details must be verified:
-
the camshafs must turn smooth in the cylinderhead, provide free travel by machining where needed
-
distance between valve seal and retainer at full lift must be 0.6mm at least
-
minimum valve spring travel of 1.0mm at full lift must be provided
-
distance between valve and piston 1.0mm (pref. 1.5mm). check 5-15° before TDC on exhaust, and after TDC on intake
#
ONLY for dirt track applications and pro street use with adjustable engine management or carburettors
#
for TURBO conversion (atmospheric to turbo)
#
In some cases machining of the cylinderhead can be required due to camshaft casting tolerances.
