The oil cooler above the filter is leaking very bad, and I need to replace the gasket,but I had no prior leaks before and it was hard to start my vehicle. You can't just buy the gasket for the cooler, unless it's the newer silver oil cooler, the part alone is at least $400, but there seems to a frequent issue of this with many others, on the 2008 Mazda Cx-7.
