Cam & Timing Set Questions
Just thinking out loud here.
But every time I hear of a cam going flat I keep thinking about some type of "Dummy Engine" that the only job of it is to break in cams.
Super light valve springs to polish in the cam and lifters. Valve guides on the loose side could be advantageous too.
Maybe even some oil system mod that would excessively flood the cam and lifter bases with oil to keep it flushing clean as it is breaking in. This would be a good place for a high volume oil pump to supply the feed.
Get the cam and lifters broke in, then swap them over into the expensive engine build you just put together.
Good to Go . . .
There are lots of other variations on how this could work out, but this is the first step thought on it for now.
Just think about all the fines that get in the oil from the new piston rings that are knocking down the fresh cross hatching in the cylinder walls to break in then that gets filtered and right back across the new cam and lifters trying to break in, some of those extreme fines have got to be getting through.
So by rights, the dummy engine long block should be already broke in and loose before attempting to use it for a cam break in machine.
Then the only thing that has to break in and mate up is the new cam to lifter surfaces. Giving full focus to these areas with the best supply of clean oil, as the rest of the engine has already been run in.

Some thoughts if these cam/lifter break-ins are going to continue to be an issue for the future???
