Information:
Cylinder Heads Without Guides Cylinder Heads With Guides New cylinder heads have been introduced on the 4.236 engine. The new heads have replaceable valve guides. The differences between the earlier and current heads are explained below. The change became effective at engine number LD---U040236M and up. See General Information in Systems Operation for the engine serial number location.Double valve springs:(1) Outer spring: Length under test force ... 45.22 mm (1.780 in)Test force ... 178 9 N (40 2 lb)(Damper coils of spring go toward cylinder head).(2) Inner spring: Length under test force ... 39.70 mm (1.563 in)Test force ... 69 4 N (15.4 1 lb)(Damper coils of spring go toward cylinder head).Single valve springs (not shown). Length under test force ... 41.4 mm (1.63 in)Test force ... 251 13 N (56.4 3 lb)(No damper coils).Cylinder Heads Without Removable Guides
