My brothers 89 GT is got way to much oil pressure at idle it reads 80 psi and at full throttle it pegs the 100 psi limit. Hes running a auto meter mechanical oil pressure gauge with no kink are tight bend in the line hes running 20-50 oil but just switched to 10-30 to see if it does any thing. He has also got the Melling high VOLUME pump but im sure that it doesn't produce that much pressure. We are trippin that it might burn a bearing or blow out seals. help us out. <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>FasterDamnit</b> <br /><small>Member # 442</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(2003,4,28,12,19,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> If the plug for the pressure relief spring was pushed in too far then the Pressure can run that high.
