What do pushrods and lifters do in an engine?

The pushrods and lifters work with the camshaft and rocker arms to open the engine’s valves. This basic setup has changed little since the earliest days of pushrod engines. The only major change in these components has been roller lifters replacing flat bottom lifters on late model engines.

How are yoke and valve adjustments done on an E7?

Yoke and valve adjustments are done in two stages on E7 engines. Adjust the yoke clearance first, then adjust the valve lash. Make sure both adjustments are done in firing order sequence.

What is the firing order for an E7 engine?

E7 engine firing order is 1-5-3-6-2-4. Some E7 engines built in early 1995 may be equipped with flywheels that have missing or illegible valve adjustment markings. If this problem is encountered, a typical flywheel can be marked while the engine is in the chassis.

Where is the pointer on an E7 engine?

Some E7 engines are equipped with a pointer on the timing gear cover and marks on the vibration damper. To adjust the yoke and valves on these engines, bar engine in normal rotation direction until the TC mark on the damper (with the No. 1 piston on the compression stroke) aligns with pointer marked VALVE.
