<div dir="ltr" data-setdir="false"><span><cite class="ydp93995a00algo-display-url">I've read all of the comments, but haven't heard anything about Cometic. I had rebuilt my TR-3 engine a number of years ago, using the stock head gasket. I built the engine as I would have built one of my race engines in the day, except with a milder cam and less compression (10.5:1). From day 1 it never really ran right. I began to suspect coolant was getting into the combustion chamber, so I bought one of those test kits where you pull some coolant out while the engine is running and add a chemical which tests for hydrocarbons. Sure enough, hydrocarbons were getting into my coolant system. That says bad head gasket or crack in the head. Since I'd had the head magnafluxed during the rebuild, I assumed it was the head gasket.</cite></span></div><div dir="ltr" data-setdir="false"><span><cite class="ydp93995a00algo-display-url"><br></cite></span></div><div dir="ltr" data-setdir="false"><span><cite class="ydp93995a00algo-display-url">I began asking around about where I could get a good gasket. A guy at a local engine shop (primarily Ford engines) recommended Cometic. I had never heard of them, and told him the engine was over 50 years old, so surely they would not make a gasket for it. He encouraged me to check the internet, and sure enough, they make a whole bunch of them for the TR engine. It's been a few years ago, but as I recall, they had gaskets for different bores (i.e. 83MM, 86MM, 87MM, etc.) and you could order different thicknesses. They stacked steel gaskets on top of each other to get to the thickness desired. I think I ordered a 3 layer gasket. It all sounded a little fishy, but based on the strong recommendation I had received, I ordered one.</cite></span></div><div dir="ltr" data-setdir="false"><span><cite class="ydp93995a00algo-display-url"><br></cite></span></div><div dir="ltr" data-setdir="false"><span><cite class="ydp93995a00algo-display-url">I removed the bad head gasket and replaced it with the Cometic gasket, and suddenly the engine ran great. I have put almost 7.000 miles on the car since then and haven't had a problem. It runs cool (even on 95 degree days, as tested recently), pulls strong, and no sign of any coolant leaks. By the way, I noticed someone else recommended Hylomar gasket cement. I also used that. A light coat on all sealing surfaces does the trick. Do not spray a thick coat. Below is the link to the Cometic web site. Check it out.<br></cite></span></div><div dir="ltr" data-setdir="false"><span><cite class="ydp93995a00algo-display-url"><br></cite></span></div><div dir="ltr" data-setdir="false"><a href="https://www.cometic.com/" rel="nofollow" target="_blank" class="enhancr_card_6247372032">Cometic Gasket - Sealed Under Extreme Pressure</a></div><div><br></div><div id="ydp48b58523enhancr_card_6247372032" class="ydp48b58523yahoo-link-enhancr-card ydp48b58523yahoo-link-enhancr-not-allow-cover ydp48b58523ymail-preserve-class ydp48b58523ymail-preserve-style" style="max-width:400px;font-family:YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif" data-url="https://www.cometic.com/" data-type="YENHANCER" data-size="MEDIUM" contenteditable="false"><a href="https://www.cometic.com/" style="text-decoration-line: none !important; text-decoration-style: solid !important; text-decoration-color: currentcolor !important; color: rgb(0, 0, 0) !important;" class="ydp48b58523yahoo-enhancr-cardlink" rel="nofollow" target="_blank"><table class="ydp48b58523card-wrapper ydp48b58523yahoo-ignore-table" style="max-width:400px" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td width="400"><table class="ydp48b58523card ydp48b58523yahoo-ignore-table" style="max-width:400px;border-width:1px;border-style:solid;border-color:rgb(224, 228, 233);border-radius:2px" width="100%" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td><table class="ydp48b58523card-info ydp48b58523yahoo-ignore-table" style="background-color: rgb(255, 255, 255); background-repeat: repeat; background-attachment: scroll; background-image: none; background-size: auto; position: relative; z-index: 2; width: 100%; max-width: 400px; border-radius: 0px 0px 2px 2px; border-top: 1px solid rgb(224, 228, 233);" cellspacing="0" cellpadding="0" border="0"><tbody><tr><td style="background-color:#ffffff;padding:16px 0 16px 12px;vertical-align:top;border-radius:0 0 0 2px"></td><td style="vertical-align:middle;padding:12px 24px 16px 12px;width:99%;font-family:YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif;border-radius:0 0 2px 0"><h2 class="ydp48b58523card-title" style="font-size: 14px; line-height: 19px; margin: 0px 0px 6px; font-family: YahooSans, Helvetica Neue, Segoe UI, Helvetica, Arial, sans-serif; color: rgb(38, 40, 42); max-width: 314px;">Cometic Gasket - Sealed Under Extreme Pressure</h2><p class="ydp48b58523card-description" style="font-size: 12px; line-height: 16px; margin: 0px; color: rgb(151, 155, 167);">Cometic Gasket supplies hi-performance gaskets for a variety of motorsports markets: ATV, Drag Race, Domestic Au...</p></td></tr></tbody></table></td></tr></tbody></table></td></tr></tbody></table></a></div>Jack<div><br></div><div><br></div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false"><br></div><div><br></div>
