p38 oil cooler

just to remind all those with oil coolers,don't forget to flush them out periodically,i did mine the other week,and i was surprised how much sludge and crud there was in there,mine is a bmw 2.5 lump,and bmw lumps do not like any foreign bodies floating in them,it causes big problems,to get long life out of any bmw engine ,you have to maintain it,check oil level,this is critical,as the top end gets starved if it gets too low,it doesn't take long to check,too late when the damage is done.
while your there flush out intercooler as well
