Quote from: 1969chargerrtse on July 05, 2008, 06:43:14 AMI've put 2,000 miles on my rebuilt motor and used Valvoline ZR1 racing oil from day one. It is listed as racing oil because it has the Zinc in it. Please confirm this oil is o.k and I need to do nothing else?
Quote from: FLG on July 05, 2008, 06:20:18 PMHow can you tell the older better Rotella from the newer stuff? Local gas station has bottles that look like they been sitting for quite some time..so i may buy up a stock if its the older better stuff.
Quote from: toupee on July 05, 2008, 11:28:35 PMAlright, I'm lost. So this problem applies to basically all non roller engines? That's a lot of people. And no company's have to make an announcement about this? Seems like they would be setting themselves up for lawsuites from a bunch of vintage car buffs if motors start failing all over the place in the next few years.
Quote from: mally69 on July 06, 2008, 09:02:13 AMJust a queston, but what do most cars have in there for lifters today. Are they all roller?? What would my 4.7 in my dakota have in there.?

Quote from: RallyeMike on July 07, 2008, 12:55:50 AMWell, I'll add my story: Two flat cam lobes and crap that fouled up a piston skirt likely as a result. Complete tear down, hone, and rebuild with new pistons, cam and bearings. Just got the engine back in the car today. It had about 600-700 (hard) miles on it. I was using Mobil 1 20-50W, which a couple years ago was fine. Did not realize the formula had changed once again since I last checked it out. I need to pay more attention to this crap !
