Goodbye Crane Flat Tappet. I hardly knew ye.

I did drop from 60 to 50 psi overnight. Also another reason I decided to pull the intake off. I was always told that once the cam is broken in that zinc didn't really matter. Is that incorrect?

From what I understand zinc does matter! But I was ignorant to this info until I got on this forum,years ago. I Have yet to use a zinc rich oil and after 40k miles I`m gonna pay for it. I`ve got a few front lifters showing a wear issue that I need to address with a new cam/lifters.
I told a buddy of the synthetic/pressure issue and he was thinking the syn. may have broke loose any/all crap in engine and clogged the filter? that pressure issue I had is no bs. This happened years ago, been driving the car ever since, When I do a new cam, I will have the proper oil or go roller, I`m thinking roller and heck with the high$ oil. I don`t know, either/or may balance equal in cost overall or long term?
