I don't think anyone brought up the ZDDP that was removed (reduced) from most oils. This makes high performance flat tappet cams much more likely to wipe a lobe. The roller is more durrable with todays oil. Although there are problems with solid rollers in certain engine families (not sure all engines have this problem). There are many thread on this, so do some searchs and read up. It is a very interesting subject (at least to engine geeks). |
