Comp makes break in oil that is about $10 per bottle. They recommend putting that in your first oil during break in, then change the oil after 1000 miles or so and run another bottle in the oil for a full oil cycle. Rollers lifters do not need to break in mating surfaces like flat lifters do, but there are many other moving parts that need to get to know each other besides the cam and lifters. I run Comp break in oil for 1000 miles each time I change an internal component. I also run VR1 oil, which also has the good stuff in it.

As far as break in, I do not have any scientific reason for this, but I break the motor up to operating temp at 2000-2200 rpm several times in the garage before I take it out on the street. This gives me a chance to check the fluids, check for leaks, readjust bolts and nuts, etc. I then put it on the street and drive it for about 20 miles before I push the dog **** out of it. If it breaks, I missed something and now know what it is. Most of the time, I am good to go.

 

I'm running Joe Gibbs Racing break-in oil and a bottle of the CompCams cam break-in lube. Likely do a change at 500miles, use the JBR oil and CC lube again till 1500 since I'll be on a 1000 mile trip with only about 700miles on the engine. Been thinking about running the VR-1 oil after that.

The initial start of a new engine is more than just the cam. As stated above there are many other moving parts which need to seat and mate properly as well as pressure build up and a multitude of other things that can happen. Better to spend the bit of extra time in the garage to watch and listen then to have something blow 1st trip out on the road.

 

Get everything right (hoses, nut and bolt, etc., start it up, set the idle, and the timing, and then waste no time driving the **** out of it.

That is my style of break in anyway.

Does that make me "bad"?
