You wont see any cracks as such because its under hot pressure, so the oil cooler will look normal to the naked eye, they normally go up the top of the oil cooler the first one or two radiator fins, sometimes it can leave a very slight rust effect along where the leak could be.

Either way, its replacement oil cooler time, and look forward to a lot of system flushing.

And then when you think you've flushed it clean, give it a couple of days of use, then flush and............... ;D

If buying from Courtenay, make you deduct the Inlet Manifold Seal Kit, which you don't need, re use the old ones.

Interestingly the Courtenay Coolers ones are Stainless Steel (as supposedly fitted to the late 2.6 and 3.2 models), all the failed coolers Ive come across were 2.6 and 3.2's, yet to see one on the 2.5 / 3.0's  :-\

99.99999% it will be the cooler, assuming no water (mayo) in the oil.

All coolers are stainless, except very early ones 1994/5.  Stainless ones still fail if you don't service the coolant
