He is also running methanol injection with only 18lbs. of boost, which is totally fine. The customer had too rich of a tune causing washed cylinder rings & thinned the oil. <br /> When HCI inspected the motor there was minor detonation, washed cylinder rings and just the rod journal bearings had been worn down to the copper coating; which is the last layer in the Clevitte's Tri-metal bearing.<br /> We are unsure as to wether this is a flaw within the smaller Clevitte bearings or as WE ALL KNOW no build can withstand a bad tune.<br /> Any educated opinion is appreciated. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>jayl</b> <br /><small>Member # 185</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(2007,10,3,16,44,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> You have a PM <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
