I have an 2006 m35x with an oil leak from the oil cooler. I have had the O ring replaced two times in the last month from an import car garage (not dealer) and it is still leaking. They think I need a new cooler which is very expensive. Is there a chance they are not putting the O ring on correctly or is it a pretty basic job? Has anyone had to replace the oil cooler itself because of a leak?
