I have replaced the lifters rocker arms

for the problem

Perhaps the camshaft has a bad lobe.

Correction – if you push down on the rocker arm on the fourth cylinder it stops

If everything replaced was the correct part....sure makes me wonder if it is a lubrication problem (to the lifter), a worn valve stem or a flat cam lobe.
