I had the same problem back in 2016-2017. I tried everything including crack checking the head. Changing out the head solved the problem. Hopefully you have an extra race prepared head.<div>I have seen casting leak on other cars due to lack of casting density.<br><br><br><div class="yahoo-signature">Mike Munson #28 EP TR6</div><br><p class="yahoo-quoted-begin" style="font-size: 15px; color: #715FFA; padding-top: 15px; margin-top: 0">On Monday, September 25, 2023, 1:40 AM, Anthony Parker via Fot <fot@autox.team.net> wrote:</p><blockquote class="iosymail"><div id="yiv6354514897"><style type="text/css">#yiv6354514897 P {margin-top:0;margin-bottom:0;}</style><div dir="ltr">
