4.6 oil cooler does it need flushing?

Does anyone know whether there is any useful purpose served by taking the oil cooler off a 4.6 and flushing it out? I'm showing my ignorance here, but I think its done on diesel intercoolers to improve performance, but will it make any difference to mine? It may sound odd, but I've noticed the engine 'smells' hot and oily after a run. Water temp is ok and theres no water loss. I'm going to change the oil/filter this weekend and will look at the oil cooler if theres any benefit in doing so.

the cooler has oil running through it all the time so if you change the oil it should flush it through anyway.

If you can smell hot oil is there a leak there? May not be a big one, but could be dripping oil onto a hot area? Probably worth checking.

Hiya MSM...you could be opening a can of worms trying to remove and flush the cooler through as the pipe nuts to the cooler get corroded to the aluminium and removing them could strip the threads. Result....new cooler.

Just give the car a run to get it up to temperature, then drain the oil as normal..be careful because the oil will be very hot, but it will flow out of the sump drain hole like water and carry all the ****e with it.
If the oil is very ****ty, it would pay you to give it a dose of flushing oil after draining the old oil first, but normally that is not needed.
I appreciate your enthusiasm, but if it has been regularly serviced and "It aint broke..dont fix it"
