A few....
1) specify the type of= engine and aircraft
2) check th= e obvious things first:
Is there enough oil?
=
Is the oil freely moving through the oil cooler?
Was it working fine before? Or was the oil a= lways too hot?

If it is a recent problem, what changed= ? (Change it back)
If it is a chronic problem with this aircraft, what is the air pressure drop across the cooler= ? What is the air temperature increase after passing through the oil cooler?= Is the right oil cooler installed?
<= div style=3D"" class=3D"">
It is not a= t all clear to me that the warm oil is an indication of a fuel problem. = ;
If all 4 or 6 cylinders are running smooth= ly ROP and LOP, then the problem is heat removal, not fuel supply. If the CH= Ts are OK, then the problem is specifically about the oil system, and not ai= rflow over the cylinders.
Changing the fuel system when the oil cooler is clogged would just compou= nd the problems.
