We had a bad problem with serious coolant leaks right across the head, and that was after the block and head had been to the machine shop and checked for any distortion. It turned out to be the head gasket. It was a new one that came with the Moss head gasket set, but it failed completely. I paid out big dollars for an upgraded head gasket and the problem was cured. I have about 3500 miles on it now.<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'>Regards, Mirek<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US>From:</span></b><span lang=EN-US> Healeys <healeys-bounces@autox.team.net> <b>On Behalf Of </b>Roger Grace<br><b>Sent:</b> Sunday, January 7, 2024 3:41 PM<br><b>To:</b> Healeys <healeys@autox.team.net><br><b>Subject:</b> [Healeys] Fwd: Glycol in oil<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Up date.<o:p></o:p></p></div><div><p class=MsoNormal>So re-torqued head.
