Pushrod engines actuate the valves like this:
cam -> lifter -> pushrod -> rocker -> valveOverhead cam engines do it like this:
cam -> lifter -> valve (basically)
Pushrod setup:
_________ ___
/_________O____\ <- rocker
|| ||
|| <-valve ||
|| ||
/__\ || <- pushrod
||
||
||
||
||
| |
| | <-lifter
|__|
/ \
/ __ \
| (__) | <-cam
\____/
Then, for an overhead cam, imagine putting the cam up on top of the valve. Then you don't need the pushrod.

what does "pushrod" refer to? what do engines that do not use this use instead?
thanks
