Re: [FWDLK] Timing is everything: Adjusting valves

[David Homstad <dhomstad@xxxxxxxxxxx>]

Dan,

In theory, your process should work. That's what I tried the first time, but
I didn't get good results. So I came up with the following method for my
D500 which sets each valve when the cam lobe is close to 180 degrees away.

Valve lash adjustment procedure (56 D500 only, all other Dodge Hemi/Poly V8s
are hydraulic): [ref. Mopar Performance "Engines" book, P/N 4452790, page
141]: Firing order: 1 8 4 3 6 5 7 2.  Rotation: clockwise when viewed from
the front. Cylinder layout on driver's side: 1 3 5 7. Passenger side: 2 4 6
8. Start by finding TDC on cylinder # 1 during its compression stroke (both
valves closed and time for the spark). For each succeeding cylinder, rotate
the engine 1/4 turn and use a long blunt probe (large screwdriver that will
not fall in) in the spark plug hole to find TDC. For the valves being
adjusted, the cam lobe peak will be 180 degrees opposite the lifter.

  Cylinder #      adjust       adjust
    at TDC        intake       exhaust
     1              2            8
     8              1            4
     4              8            3
     3              4            6
     6              3            5
     5              6            7
     7              5            2
     2              7            1

OK, time to break down and adjust the mechanical valves in the 318.  Here's
the firing order: 1-8-4-3-6-5-7-2.  So, I get the engine good and warm, then
pull one of the valve covers, adjust the valves, put the cover back on, warm
up the engine again, pull the other valve cover and repeat.  Correct?

Now, on the assumption that both intake and exhaust valves are closed with
the piston at TDC on a combustion stroke -- can I do the adjustment on the
following schedule, from the starting position of an alignment of the timing
marks?

Left bank:      set timing marks
                adjust #1 cylinder
                turn crank 3/4 turn
                adjust #3 cylinder
                turn crank 1/2 turn
                adjust #5 cylinder
                turn crank 1/4 turn
                adjust #7 cylinder

Right bank:     set timing marks
                turn crank 1/4 turn
                adjust #8 cylinder
                turn crank 1/4 turn
                adjust #4 cylinder
                turn crank 1/2 turn
                adjust #6 cylinder
                turn crank 3/4 turn
                adjust #2 cylinder

Does that sound about right?  Does anyone have any tips for me?
