How do I know if they're adjusted too tight? Will the engine still crank and fire?<br />I was told to lash them down till the pushrod doesn't spin then 3/4 to 1 full turn more. <br />All replies appreciated <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>93sspCOUPE</b> <br /><small>Member # 8418</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(2010,8,3,3,42,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> If there hydraulic roller liffters then yes if there solid roller litters then no you need feeler guages. Most of the time that's just a base to start with hydrualic litters need to be adjusted correctly with the engine running it's messy but it's the best way <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Maxoctane</b> <br /><small>Member # 1466</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(2010,8,3,20,7,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Turned out it had a collapsed lifter. So I replaced the lifters and adjusted the rockers to Comp Cams specs. Which is; <br />With the lifter on the base circle tighten down till you can feel drag as you turn the pushrod. Then 1/2 turn more.<br />Prob solved.<br /> <br /> <small>[ September 03, 2010, 10:20 PM: Message edited by: Maxoctane ]</small> <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
