CAMSHAFT (EXH) JOURNAL OIL CLEARANCE
(Oil clearance) = [VVEL ladder assembly (EXH side) inner diameter] - [Camshaft (EXH) journal diameter].
Standard and limit: Refer to "CAMSHAFT ".
If the calculated value exceeds the limit, replace either or both camshaft (EXH) and VVEL ladder assembly & cylinder head assembly.
NOTE: VVEL ladder assembly cannot be replaced as a single part, because it is machined together with cylinder head assembly.
