Engine timing is adjusted when pistons are locked in 90 positio

This is an updated procedure that eliminates using top dead cen

(TDC) when setting camshaft and crankshaft correlation.

Special tools and procedures are required to remove and install

VANOS units and to time camshafts.

Check camshaft timing. See Camshaft timing, adjustingin thirepair group.

WARNING

To avoid personal injury, be sure engine is cold before

beginning the procedure.

CAUTION

Disassembly, removal and assembly of camshafts or VANOS

units without special tools poses the risk of damage: Valves

may be bent by contact with the piston crowns.
