Question about 1993 Nissan Sentra 4 Door
I just got through replacing the head gasket on a qg18de motor on a 03 sentra, i rotated the crank to tdc ( red line on the harmonic balancer) but im havin trouble with the cam gear ttiming. my chain only has one blue link which is for the crank im guessing due to the fact that no colored link is visable and it is at tdc now. ive already torqued the head bolts and only have to time the cams up. where do i start as far as timing the cams up? cam settings???

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.
