measured height underruns its limit, replace camshaft.
Cam height “a”
[For engine with VVT]
[For engine without VVT]Camshaft Runout
Set camshaft between two “V” blocks, and measure its
runout by using a dial gauge.
If measured runout exceeds limit, replace camshaft.
Camshaft runout limit
0.10 mm (0.0039 in.)
Camshaft Journal Wear
Check camshaft journals and camshaft housings for
pitting, scratches, wear or damage.
If any malcondition is found, replace camshaft or cylinder
head with housing. Never replace cylinder head without
replacing housings.
Check clearance by using gauging plastic. Checking
procedure is as follows.
1) Clean housings and camshaft journals.
2) Remove all tappets with shims.
