<html><body><div>I just rebuilt my 100 engine and purchased my lifters from AH Spares in the UK. These were their new design for better oil flow. I now have 1000 miles or so on the new engine and once I got my problems figured out with my distributor, the car is running well and smooth.</div><div> Now I'm wondering when the other shoe is going to drop! What problems did you have pointing you to the lifters as the source of those problems? When I retorqued the head, I readjusted the rockers and found no problems. They were a little off, but I expected a little.</div><div> What should I be looking for? I used Driven Break In oil and then I switched to VR1 like you after 500 miles. I have been driving the car to build up some trust in it and it's turning in to a joy to drive. I've got M mods on this engine, cam, H6 carbs, M pistons and these new lifters. So far, so good. </div><div> Thanks for your help,</div><div>Steven Kingsbury</div><div>BN1</div><div><br>On August 3, 2021 at 5:19 PM, Michael Salter via Healeys <healeys@autox.team.net> wrote:<br><br></div><div><blockquote type="cite"><div class="msg-quote"><div dir="auto">After only 6000 miles the NOS BMC lifters that I installed in my engine with a very low mileage "M" cam have started to deteriorate. <div dir="auto">This engine has had a steady diet of VR1 non synthetic and it has had 4 changes in 6K miles. </div><div dir="auto">Very disappointing. </div><div dir="auto">I'm considering trying bucket type Buick lifters with longer push rods and a new cam.</div><div dir="auto">Does anyone have experience with the durability of the old Buick lifters ... getting a little desperate here.</div><div dir="auto">Fortunately I caught this issue before it ruined the engine.</div><div dir="auto"><br></div><div dir="auto">M</div></div><div class="_stretch"><span class="body-text-content">_______________________________________________<br>Support <a href="http://Team.Net" data-mce-href="http://Team.Net">Team.Net</a> <a href="http://www.team.net/donate.html" data-mce-href="http://www.team.net/donate.html">http://www.team.net/donate.html</a><br>Suggested annual donation $12.75<br><br>Archive: <a href="http://www.team.net/pipermail/healeys" data-mce-href="http://www.team.net/pipermail/healeys">http://www.team.net/pipermail/healeys</a> <a href="http://autox.team.net/archive" data-mce-href="http://autox.team.net/archive">http://autox.team.net/archive</a><br><br><a href="mailto:Healeys@autox.team.net" data-mce-href="mailto:Healeys@autox.team.net">Healeys@autox.team.net</a><br><a href="http://autox.team.net/mailman/listinfo/healeys" data-mce-href="http://autox.team.net/mailman/listinfo/healeys">http://autox.team.net/mailman/listinfo/healeys</a><br><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/airtightproductions@icloud.com" data-mce-href="http://autox.team.net/mailman/options/healeys/airtightproductions@icloud.com">http://autox.team.net/mailman/options/healeys/airtightproductions@icloud.com</a><br><br></span></div></div></blockquote></div></body></html>
