Step 10: Repeat the degreeing process on the intake camshaft.
Step 11: Repeat the degreeing process on the opposite cylinder bank, this time using the number 6 exhaust and
intake valves to check lift centerline. Note that it is not necessary to reestablish TDC in order to verify the #6
intake and exhaust centerline.
intake valves to check lift centerline. Note that it is not necessary to reestablish TDC in order to verify the #6
intake and exhaust centerline.
In the event that your camshaft did not degree in to the camshaft specification, it will be necessary to either
advance (move the cam ahead) or retard (move the cam back) the camshaft to meet the suggested intake/exhaust
centerline. There are generally a couple of degrees of advance/retard available by loosening the timing gears
(lock the camshafts again before loosening the bolts!) and rotating the crankshaft until the pointer is positioned
at the desired intake/exhaust centerline reading. Refer back to step 9 if you do not remember how to determine
that reading. Note that any changes that you make to the intake centerline will require re-verification and
adjustment of the exhaust centerline.

Note: When degreeing a cam, remember to look at the degree wheel as two 180 degree sides, no matter
how the degree wheel you are using is marked. Many degree wheels are marked in 90 degree increments.
On wheels that are marked in 90 degree increments, keep in mind that you must continue to count the
number of degrees on past 90 degrees. Be sure all readings are taken from Top Dead Center.

Keep in mind that to advance the cams, you must lower both the intake and exhaust centerline. For example, if
your camshaft set has a lobe separation of 114 degrees, moving the intake centerline to 110 degrees advances
the cam set 4 degrees. Conversely, moving the intake centerline to 116 degrees retards the camshaft set 2
degrees. Note that it is very important that with the 4.6-liter 4 valve engine, any advance/retard adjusted into the
intake cams must also be reflected in the exhaust cams.
