Camshaft break in oil additive
I have had my 4.0 rebuilt. I installed a new camshaft. Inside the box of the camshaft there was a piece of paper titled " Camshaft break in engine oil warning." It states that modern day oils do not contain enough zinc to protect the flat tappet camshaft during break in.
It recommends 3 ounces of there ZDDP cam shield additive.
Is there some sort of generic version of a zinc additive i can get at a local auto parts store?
Has anyone else heard of needing a additive for camshaft break in?

yes, it is strongly recommended to use a break-in oil with zinc. my preferred brand is Brad Penn. Those who say don't worry about it obviouslly don't rebuild engines often enough to know better.

FWIW, consider that Brad Penn break-in oil is 1073 Zinc/931 Phosphorous.
The Rotella I suggested comes back from Blackstone as follows:
Zinc - 1208 PPM Phosphorus - 989 PPM, nearly identical to both Brad Penn and Edelbrock break-in oil. And much easier on the pocketbook. Any of them would appear more than sufficient for a low-pressure street cam. Agreed on not using typical passenger-car motor oil.

Golen Engines sold me 6 quarts of Joe Gibbs break-in oil for my stroker.
And they highly recommend a ZDDP additive at every oil change.

That is a good point. It's been several years and I don't know if they've changed their forumula recently or not, it's not as though they'd tell anyone, lol. I may send some in to Blackstone to see what comes back.
I have a 383 stroker (GM, not Jeep) with a flat tappet cam, I've run nothing but Rotella since building it with no issues. But your point is an interesting one, I may have broken it in back before the formula changed, depending on when and if it has.

.......and those that do build engines often obviously know that one should never ever install anything but stock, low pressure valve springs (preferably used) in a new flat tappet push rod motor for the initial "break-in". After the break-in, install whatever springs.
