Fortunately for me, I had Greg Solow advising me during my build. When I first checked the protrusion, I had really low measurements along one side of the block. I actually had the block machined on a slight angle to clean it up. That gave me higher protrusion than the .003-.005" spec. at .006-.007". So I think it's better to be on the high side than shorter than .003" of the factory spec.</div><div aria-label="Compose body">If I recall correctly, when I torqued the head without a gasket in place it went to .001" around 40lbs. of torque with the .006-.007" protrusion. So something is squishing or giving quite a bit when the head is getting torqued. </div><div aria-label="Compose body">This is why a torque plate should always to used when the liners are bored. The liners change shape under pressure.</div><div aria-label="Compose body">I wouldn't get too hung up on what is happening with the head on torque measurement, but .008" with the head off seams a little high. But I thought .006-.007" was high too.</div><div aria-label="Compose body">Really, at that point I decided to just put the thing together.</div><div aria-label="Compose body">With the head off, are you still getting .008" protrusion?</div><div aria-label="Compose body">The only reasonable thing you can do to change that, is change the figure 8 or take a little off the top of the liners.</div><div aria-label="Compose body">Perhaps Ken can advice you better than me.</div><div aria-label="Compose body">Man, is everyone using 89mm pistons now? </div><div aria-label="Compose body"><br></div><div aria-label="Compose body">Dave</div><div aria-label="Compose body"><br></div><div><br></div><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><b>From: </b>"Michael Moore" <mmoore@mtmcpafirm.com><br><b>To: </b>"Tony Drews" <tony@tonydrews.com><br><b>Cc: </b>"davehogye" <dlhogye@comcast.net><br><b>Sent: </b>Wednesday, December 16, 2015 5:18:03 AM<br><b>Subject: </b>RE: [Fot] Liner Protrusion, TR-4<br><div><br></div>Tony and Dave,<br><div><br></div>This is my first racing engine rebuild (2nd engine rebuild I have ever done), and I am trying to figure out each step as I go, so any advice would really help.

My new liners dry fitted with "stock" figure 8 gaskets (0.020" thick) have 0.010" protrusion. Too much, I know. So, I'm going to make my own fig 8 gaskets out of shim stock. I have my choice between 0.015" <br>shim stock and 0.012" shim stock which would give either 0.005" or 0.002" protrusion dry. Any thoughts on which way I should go? I'm assuming that when I put some goo on the fig 8 gaskets to ensure that they seal that I'll get another thou or two protrusion so would go with the 0.012" shim / 0.002" protrusion.<br><div><br></div>I'll be running the Cometic gasket with the fire rings.<br><div><br></div>TIA<br><div><br></div>Cheers, Tony Drews<br><div><br></div>_______________________________________________<br>fot@autox.team.net<br><div><br></div>http://www.fot-racing.com<br><div><br></div>Donate: http://www.team.net/donate.html<br>Archive: http://www.team.net/archive<br>Forums: http://www.team.net/forums<br>Unsubscribe/Manage: http://autox.team.net/mailman/options/fot/mmoore@mtmcpafirm.com<br><div><br></div><br></div><div><br></div></div></body></html>
