What sequence did you follow?<br /><br />Set them to the proper pre-load, and no further. Also use a torque wrench since they are pedestal rockers and ensure that the torque value is in range simultaneously with the pre-load. (i.e. wiggle the pushrod till it 'drags', and then go 1/2 a turn further).<br /><br />If not you fuck the whole thing up. Trust me on that one :/ <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>rokcrln</b> <br /><small>Member # 2536</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2003,5,2,18,5,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> [QUOTE]Originally posted by shade-tree:<br />[ (i.e. wiggle the pushrod till it 'drags', and then go 1/2 a turn further).<br /><br />Sounds like the old chevy's I have done in the past.
