I would have said the opposite. Pipe threads generally need sealant, I thought. I use TPFE pipe dope and stay away from the tape where passages may get fouled by little strings that tear off (thank you Randall, may you rest in peace). I have had issues with new petcocks leaking which I solved by taking them apart, cleaning the bore really well and then polishing the cone. I seem to remember I put it in the drill press and used 2000 grit wet sand paper to achieve a very smooth surface. So far, so good.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Bob<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Triumphs [<a href="mailto:triumphs-bounces@autox.team.net">mailto:triumphs-bounces@autox.team.net</a>] <b>On Behalf Of </b>John Linney<br><b>Sent:</b> Sunday, September 13, 2020 12:30 PM<br><b>To:</b> David Friedlander<br><b>Cc:</b> TR3 Triumphs; New England Triumphs<br><b>Subject:</b> Re: [TR] Small coolant leak<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Correct.

No threads on stem of the petcock. Seems to me, like Tom said, these either stop leaking because they get full of crud or people just plug the hole. As it is, the valve is located just above the starter so that's where it drains! I'm guessing that if anyone wanted to drain their engine block, they'd just use the radiator petcock instead.<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Dave<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal>On Sun, Sep 13, 2020, 3:14 PM John Linney <<a href="mailto:john@linneyweb.com">john@linneyweb.com</a>> wrote:<o:p></o:p></p></div><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0in 0in 0in 6.0pt;margin-left:4.8pt;margin-top:5.0pt;margin-right:0in;margin-bottom:5.0pt'><p class=MsoNormal style='margin-bottom:12.0pt'>I went through 3 valves on my TR4.
