6.
Remove all eight spark plugs, this will ease rotation of the engine later.
7.
Remove water pump, front drive accessories and timing chain cover. Make sure to label, or take pictures
of, bolts and their respective positioning to help during reinstallation.
Before You Start Camshaft Removal
This new engine requires different crank locations when
reassembling each bank. During the main timing chain reassembly
you will assemble the left bank (driver side) first, and then the right
bank (pass. side), remembering that the crank positioning is
different for each bank.
Take a moment to notice the difference between the crankshaft
keyway and the crankshaft timing marker (Fig. A).
1) The crankshaft keyway will be used for positioning of the
crank during camshaft and timing chain installation.
2) The crankshaft timing marker will be used for checking
chain alignment and final timing verification.
Camshaft Removal and Re-installation
8.
Install COMP Cams® VCT Limiters (#5493) per
instructions, stop after completing step 20. Do not reinstall
the camshaft to VCT bolts in step 21. Repeat for each cam.
WARNING: When installing COMP Cams® camshafts,
you MUST install the COMP Cams® VCT/Phaser Limiters
or Adjustable Locking Plates to ensure that you do not crash
your pistons and valves together. Not limiting the
VCT/Phaser travel will result in catastrophic engine damage
(Fig. B.).
9.
Rotate the crankshaft until the crankshaft keyway (do not
confuse this with the timing mark) is positioned at the
twelve o’clock position. (Use COMP Cams® #4793
Crankshaft Socket)
10.
Ensure the camshaft bolts are positioned, as pictured in Fig.
C.
If the camshaft bolts are not in a similar position to the
picture, rotate the crank 360° and check again.
11.
Remove main timing chain tensioners, timing chain guides,
and main timing chains. (Fig. D) Use a 1½" open end
wrench on the flats on the camshaft, just behind the first
journal cap, to hold each camshaft while loosening the
tensioner bolts. It is advised to have assistance on this part
because the camshafts can try to rotate if not held by the
wrench. This could cause piston to
valve contact.
