Re: Did i screw up my cam break in?
What are the cam and valve spring specs? And did you coat the lobes and lifter faces with cam lube?
ZDDP level is higher in VR-1 than in most oils at the auto parts store, but it's nowhere close to what we had up until the 1990s. Of course, there are lots of $9.00/qt specialty oils with high levels of ZDDP, such as Joe Gibbs Driven, Brad Penn, etc.
If I ever install another flat tappet cam, I will most certainly use Driven BR30 break-in oil for the first 400 miles. http://www.drivenracingoil.com/dro/b...ak-in-oilhtml/
