What to expect after flat tappet lobe failure.

I replaced the cam, lifters, gaskets, oil and filter, 1 can of engine paint, I painted the intake and valve covers before i put them back on.
While the cam and intake were removed i poured diesel down into the oil pan to flush it out.

It was an exhaust lobe. On a daily driver.

The motor that you're talking about I would tear it completely down inspect everything and flush the block and rering it and bearing it.
