235 Rocker Arm Sequence - 10/05/03 11:46 PM
I've made a cardinal mistake as a rookie engine rebuilder. I didn't make complete notes, either mental or on paper, when tearing down my Chevy 235. In reassembling my Rocker Arms I've run into a problem of sequence by number and position on the Rocker Shafts. The very popular reprint of a factory manual lists them so:
Rocker Arm# Rocker Type Cylinder#
7 L.H.Ex. 1-3-5 Ex.
8 R.H.Ex. 2-4-6 Ex.
3 L.H.In. 2-4-6 In.
4 R.H.In. 1-3-5 In.
Can this be correct because the Rockers don't line up corectly with the valve stems?
When installed to line up correctly with the stems mine read like this:
Rocker Arm# Rocker Type Cylinder #
3 L.H.Ex. 1-3-5 Ex.
4 R.H Ex. 2-4-6 Ex.
7 L.H.In. 2-4-6 In.
8 R.H.In. 1-3-5 In.
This is reading left to right,water pump to
flywheel while facing the manifold(s) side.
Where have I gone wrong or is it possible a
set of rockers from a different GM L6 was installed in some earlier life of my engine? Go ahead take your shots at me,but staighten me out too!
Thanks.
