o lord very difficult engine to time man. word of advise don't remove the primary oil pump chain. there are no marks. line the bigger oil pump sprocket DOT to 12 oclock if you have the chain lock tool this makes life a lot easier. Both of the cam sprocket have a V6 mark on it they should be at 12 oclock. If everything line up like that u are golden. Hope this helps. If you need step by step instrutions I will help. Rate me please

each gear has a mark on it from the factory that line up with a corrrsponding mark on the engine some times they are hard to find but if you look hard enough you will find them they all must line up there is no margin for error or it will not start like now good luck Lindz

Timing the Cam to the Crank
There are several ways to time the cam to the crank. Be sure to check the manual before you install the timing chain or belt.
If the old parts are available, carefully compare the new gears or sprockets with the old ones. Check the keyway and timing marks just in case there might have been an error made in manufacturing. Sprockets are sometimes stamped backward. Its much better to find the problem during assembly, rather than waiting until problems show up after reassembly and reinstallation.
Maintaining Valve Timing
During a valve job, it is essential to keep the timing chain or belt in place to maintain correct valve timing. Position the number one cylinder at TDC. Some overhead cam engines use a single long chain for a cam drive. The chain can be wedged against its guides with a tapered block of wood.
the chain tensioner on some ohc engines must be wedged to keep the chain in position during cylinder head removal. courtesy of nissan motors.
Some engines have a lower and upper chain. These engines do not require special attention to wedging the chain. Be sure to look for hidden head bolts and check the repair manual before removing the OHC head.
