Don't take my word for it. I'm no mechanic, but there's lots of information out there on flat tappet cam failures in non racing engines due to the near elimination of zinc from engine oils because of stiffer emissions requrements. I've read detailed articles in both gas engine and diesel engine blogs. My local Detroit Diesel mechanic, with 40 years in the business, showed me an article a couple of years ago he got from his organization detailing this problem and giving lubricity numbers on all the available diesel engine oils. At that time there were only a couple of oils out there that were good enough and I can't get either of them here.

I used to build race engines for a major manufacturers race effort on the international level so unless you are talking over 100 hp per liter cam lubrication shouldn’t be a concern and if it is then something is wrong with your engine... eric ----- Original Message ----- From: Maureen Washburn To: [email protected] Sent: Monday, October 26, 2009 3:41 PM Subject: [UnifliteWorld] Re: 4 foot 'itis' Hi John went to the hughes site but am still learning can you suggest a few of the possible aditives? thanks!

No longer, now that new diesels have catalytic converters in them. Whether you like diesel oil or not, your camshaft needs an additive to continue living a long time. www.hughesengines.com has an article about it, among many others on the net. Hughes also sells an additive, or sells oil with the additive already in it. I use diesel oil (Rotella T or Delo 400) and put the additive in it for my newly rebuilt Chrysler small block.
