He said he never had a problem with them or the cams during break in. Go figure. I also have an article that says as soon as you get the motor started, run it at high rpm to seat the rings properly. They are talking about a motorcycle, so I am not sure if applies in our case, but an interesting read.</div><div dir="ltr"><a href="http://www.ntnoa.org/enginebreakin.htm" target="_blank">New Engine Break-in Procedure</a><br></div><div style="width:450px;font-family:'Georgia','Times','Times New Roman','serif';margin-top:5px;margin-bottom:5px;background-color:#ffffff"><table style="width:450px;height:170px;display:block" border="0" cellpadding="0" cellspacing="0"><tbody><tr><td colspan="8" style="height:1px;background-color:#e5e5e5;font-size:1px;border-collapse:collapse"><div style="min-height:1px;background-color:#e5e5e5;font-size:1px;line-height:0px"> </div></td></tr><tr><td rowspan="5" style="width:1px;background-color:#e5e5e5;font-size:1pt;border-collapse:collapse"><div style="width:1px;background-color:#e5e5e5;font-size:1pt"> </div></td><td rowspan="5" style="vertical-align:middle;width:168px;height:168px;background-color:rgb(255,255,255);border-collapse:collapse"><div style="width:168px" align="center"><a href="http://www.ntnoa.org/enginebreakin.htm" style="text-decoration:none!important;text-decoration:none;color:#000000!important" target="_blank"><img alt="image" src="https://s.yimg.com/vv//api/res/1.2/Z4Ek_5CNIidXeHIv3gTdxg--/YXBwaWQ9bWFpbDtmaT1maWxsO2g9MTY4O3c9MTY4/http://www.ntnoa.org/images/breakin.gif.cf.jpg" style="display:block;margin:auto" height="168" width="168"></a></div></td><td rowspan="5" style="width:1px;background-color:#e5e5e5;font-size:0pt;border-collapse:collapse"><div style="width:1px;background-color:#e5e5e5;font-size:1pt"> </div></td><td rowspan="5" style="width:14px;background-color:#ffffff;font-size:0pt;border-collapse:collapse"><div style="width:14px;background-color:#ffffff;font-size:14pt"> </div></td><td colspan="2" style="height:6px;background-color:#ffffff;font-size:0pt;border-collapse:collapse"><div style="min-height:6px;background-color:#ffffff;font-size:6pt"> </div></td><td rowspan="5" style="width:20px;background-color:#ffffff;font-size:0pt;border-collapse:collapse"><div style="width:20px;background-color:#ffffff;font-size:20pt"> </div></td><td rowspan="5" style="width:1px;background-color:#e5e5e5;font-size:1pt;border-collapse:collapse" width="1"><div style="width:1px;background-color:#e5e5e5;font-size:1pt"> </div></td></tr><tr><td colspan="2" style="width:100%;vertical-align:middle;font-family:'Georgia','Times','Times New Roman','serif'"><div style="line-height:16.5px;background-color:#ffffff;min-height:135px;width:245px"><div style="word-wrap:break-word;word-break:break-all"><span></span><span></span><a href="http://www.ntnoa.org/enginebreakin.htm" style="text-decoration:none!important;text-decoration:none;color:#000000!important;line-height:100%;font-size:18px;display:block" target="_blank"><span style="margin:0;font-weight:normal;margin-bottom:3px;font-size:18px;line-height:21px;max-height:43px;color:#000000;overflow:hidden!important;display:inline-block">New Engine Break-in Procedure</span></a><div style="font-size:13px;line-height:20px;color:#999999;max-height:81px;font-family:'Georgia','Times','Times New Roman','serif';overflow:hidden">When a cylinder is new or overhauled
