<div class="aolmail_MsoNormal">Thanks for the responses to my recent post regarding the thickness of the figure 8 gaskets. I’ve done a little more “digging” and these are my results.</div>
<div class="aolmail_MsoNormal">All of the steel ones I have of have gotten measure 0.015+. I recently ordered some non-copper ones from British Parts Northwest and they are aluminum and also measure 0.015+. These are the first aluminum ones I’ve seen.</div>
<div class="aolmail_MsoNormal">All the copper ones I have, including some used ones, measure 0.020+.</div>
<div class="aolmail_MsoNormal">I contacted Moss US and asked about their copper ones and any problems. They only had one report of water leaking, back in 2014. I was told that maybe the copper 0.020 ones were supposed to compress. I hammered some copper ones to 0.015 and they are twice as wide as the original and would not fit between the liner and the block bore. Additionally, I don’t think there is enough force to compress them.</div>
<div class="aolmail_MsoNormal">The Moss ones are from Moss UK and are now specified at 0.018 by BPNW. The BPNW part number is the same as the Moss UK part number. I contacted Moss UK by email but never got a response.</div>
<div class="aolmail_MsoNormal">I also recently ordered a Payen lower engine gasket set and the figure 8 gaskets in it are steel and measure the 0.015+, as all of the other steel ones.</div>
<div class="aolmail_MsoNormal">The one engine builder that I know who uses the 0.020 copper gaskets typically uses them on blocks that are decked with the liner seats cut to allow the 0.003 to 0.005 stick out as specified by the Triumph TR4 Workshop Manual, Pg. 1·121.</div>
<div class="aolmail_MsoNormal">I am interested in anybody who is using the copper gaskets. Please post how you are getting the proper stick out.</div>
<div class="aolmail_MsoNormal">For myself, I will continue to use the steel figure 8 gaskets. I would also be interested in anyone using the aluminum figure 8’s. Any problems? What did you get for stick out when assembled and the liners clamped in place? Personally, I don’t think I want to experiment with these.</div>
