[DeTomaso] Pantera Oil Pans

[Mark Tumbarello]

I had a similar concern when I rebuilt my motor last year, but when I removed the pan the nylocs were very snug and in no way melting or loosening. So I replaced with new. Others had concerns and suggested all metal lock nuts, but they seem to be hard on the threads. I personally think that Avid or Armando would have had changed this technique in the many years that they have been manufacturing these things if there were problems. YMMV, Mark

They're nylock nuts. From what I know about nylocks, they're not designed for "adverse" temperatures. The nuts on my new oil pan are zinc plated, with nylon inserts. And according to my handy Vol 26 of the Machinist Handbook, the section on product specifications for nylon locking nuts (commonly called "nylocks"), "...the nylon locking element is effective up to +250°F...". > > So my real question for all you engine guru's, what average temperatures can the interior of an oil pan experience over significant lengths of time? > > Realize that I'm looking for guidelines here. > > I believe that, based on the +250°F specification in the Machinist Handbook, nylock nuts are not appropriate for this kind of application. Or, at best, they're marginal, but I'd like your opinions as well.... I believe that a straight steel locking nut would be superior, rather than anything with nylon as part of it's locking mechanism. > > Thanks,> > Chris> > Chris Difani> '73 L #5829 "LITNNG"> The Electric Pantera> Sacramento, CA> Email: cdifani at pacbell.net > > _______________________________________________> > Detomaso Forum Managed by POCA> > Archive Search Engine Now Available at http://www.realbig.com/detomaso/> > DeTomaso mailing list> DeTomaso at list.realbig.com> http://list.realbig.com/mailman/listinfo/detomaso
