Re: Another cam bites the dust

["MO ( Steve Mick)" <micher@xxxxxxxxxxxxxxx>]

I was afraid this was going to happen with the later fornulated diesel oils. 
It is such a widespread problem, the cam manufactureres should give an oil 
recommendation for break in. There are Zddp additives to use with whatever 
oil you prefer, and that is what I use . ZDDPlus is the brand I am using and 
they have a website.....................................MO
