Break in oil- roller cam

[happystang]

Hi everyone,

I'm slowly getting ready to fire up the 428 for the first time! It's got a Lunati hydraulic roller cam/lifters and Harland Sharp roller rockers. I used Royal Purple assembly lube on the pushrods, rocker arms, and cam/lifters. I know that roller cams don't really have a break in, but just for some peace of mind.

I was planning on using Rotella 15-40 for break in, is this acceptable for a new motor? I use it on my roller 306 in my '69, I figure it would be fine for this as well.

From what I've read, I should change the oil and filter after about 45 minutes of run time, is this correct?

i wouldn't use the 15-40 for breakin......get either brad penn breakin 30 weight, or some joe gibbs breakin oil

I agree regarding single weight for break-in. I've always thought that '30' was just fine. Back in the day, I always put a can of 30 weight and a can of STP together for the assembly lube and then dumped it in with a remaining fill-up of 30.

I'd use something like a Valvoline VR1 10W30 or similar.  It doesn't need anything special.  Just don't use a synthetic oil.

If those are Morel lifters, they won't be happy with 15W-40 and will probably not function correctly.

10w-30 for Morels?

I'm editing my post....

You can actually run a little thicker than 10W30 with Morels, but it will depend on the oil itself.  There are some 15W40 oils that will work with them, but the kinematic viscosity is typically lower than other oils. 

A 10W30 is a safe bet....
