Why? Whats it meant to do?? Just something thats been bugging me for a while now
As the cam/followers need 20min's of good, clean, high pressure/flow of oil to reduce chance of wear.
It needs to be @ 2500 rpm for the oil flow/pressure
and for 20mins, as it needs to beheld with the oil flow/pressure to after oil got to working temp.
Also i think some of its to cover the cam producers back.
i usually do it @ 2500 rpm till oil temp has pasted normal running temps and all adnormal noises have dissappeared.
