what oil for cam break in?

Assuming it's a flat tappet, straight 30wt and a bottle of EOS. I assume you know that following correct breakin procedures is critical.
 
Good oil and extra oil. Do not add Lucas (thick honey stuff) if you are not starting the engine right away. It can collect at the bottom of the pan a STOP oil flow. GM's EOS is a good additive for running -in and engine and cam.

Hope this helps you.
 
Might want to consider doing a search under this subject, as quite a few turbo Buick motor builders such as Nick Micale recommend breaking in and / or running non-synthetic oil only, especially for break-in purposes. Or good dino oil and GM EOS, or something similiar. I would get a lot of opinions on this before making a decision. HTH
 
Break-in oil

Anybody seen or heard of the "Joe Gibbs Break-in oil". Said to be the absolute best out there just for that application.
 
Why does the cam need to be run in that specific RPM range for the break in? What is significant at that range as opposed to sitting there idling? :confused:
 
oil splash is critical ........

to lube the camshaft.
at approx 2000 rpm, the side clearance from the rods slings oil onto the camshaft lubing the cam and lifters ( which is critical for break in!)
it also puts oil onto the cyl walls, to help piston break in.
at idle, there isn't enough oil sling to adequately oil the cam & lifters.
Make sense?
 
The higher RPM gets the oil splash on the cam good (about 2,000 rpm for at least the first 20 min.)

Yeah, it makes perfect sense now, thanks.
