I measured the diameter and overall length of two different tappets according to the original service manual. (reprint) The diameter is spot on for both tappets. The follower with the four holes has the correct overall length. The three hole tappet is taller, but the bottom of the pocket where the pushrod seats is recessed further in matching the height of the four hole tappet seat. So now they both will work? If that is the case I'm leaning toward the four hole version for two reasons. One, it has the correct overall length. Two, oil will flow back out the tappet back to the pan better. Less weight going up and down too. Am I going in the right direction here? Anyone have the dimensions for the 6 cylinder tappets?<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman",serif'>Mike MacLean<o:p></o:p></span></p></div></div><div id="yahoo_quoted_9437605283"><div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'>On Sunday, May 3, 2020, 2:10:10 PM PDT, Steven Kingsbury <airtightproductions@icloud.com> wrote: </span><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><o:p> </o:p></span></p></div><div><div id=yiv8396273932><div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'>Mike,<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'> Yeah, don't know what to say.

I measured the height, 3 1/8" (maybe a smidge either way), 1" in diameter at the base, 1/2" outer diameter of the cup holding the pushrod and 2 3/4" from the base of the lifter to that same cup.

As you can see in the picture of the eight lifters, two are not the same as the rest. I bought these several years ago from Vicky Brit and they all had the same part number, but they are not the same. Two of them have eight holes in the body. The rest have three holes. The two that are different are almost an eighth of an inch shorter than the other six. That can't be good. These are the things I run into that slows progress on this engine. I suspect the two different ones are for a different application. Can someone tell me what the correct overall height of a 100-4 cam follower is? For all I know I might only have two correct lifters.<o:p></o:p></span></p><div id="yiv8396273932yMail_cursorElementTracker_1588479146474"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'>Mike MacLean<o:p></o:p></span></p><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><o:p> </o:p></span></p></div><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><br><br><o:p></o:p></span></p><div id="yiv8396273932ymail_android_signature"><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><a href="https://go.onelink.me/107872968?pid=InProduct&c=Global_Internal_YGrowth_AndroidEmailSig__AndroidUsers&af_wl=ym&af_sub1=Internal&af_sub2=Global_YGrowth&af_sub3=EmailSignature" target="_blank">Sent from AT&T Yahoo Mail on Android</a><o:p></o:p></span></p></div></div></div></blockquote></div></div></div></div></div></div></div></blockquote></div></div></div></div></div></div></div><p class=MsoNormal style='mso-margin-top-alt:0in;margin-right:1.0in;margin-bottom:12.0pt;margin-left:1.0in'><span class=yiv8396273932body-text-content><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'>_______________________________________________</span></span><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:#26282A'><br><span class=yiv8396273932body-text-content>Support <a href="http://Team.Net" target="_blank">Team.Net</a> <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a></span><br><span class=yiv8396273932body-text-content>Suggested annual donation $12.75</span><br><br><span class=yiv8396273932body-text-content>Archive: <a href="http://www.team.net/pipermail/healeys" target="_blank">http://www.team.net/pipermail/healeys</a> <a href="http://autox.team.net/archive" target="_blank">http://autox.team.net/archive</a></span><br><br><span class=yiv8396273932body-text-content><a href="mailto:Healeys@autox.team.net" target="_blank">Healeys@autox.team.net</a></span><br><span class=yiv8396273932body-text-content><a href="http://autox.team.net/mailman/listinfo/healeys" target="_blank">http://autox.team.net/mailman/listinfo/healeys</a></span><br><br><span class=yiv8396273932body-text-content>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/airtightproductions@icloud.com" target="_blank">http://autox.team.net/mailman/options/healeys/airtightproductions@icloud.com</a></span><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
