So if fixed the first leak in the front of my motor, oil filter housing, then I fixed the second oil leak which was the front main seal. Now for number three, looks like the oil cooler is leaking. The older 4.2 with a timing belt were notorious for oil cooler leaks but I have not found anything online about the C6 4.2 having oil cooler leaks. The gaskets are only $11 each times 2, but I dont want to misdiagnose the leak.

after you do fix that oil leak you should really inspect the crankcase vent system, it may be plugged up or the valve bad causing too much crankcase pressure and causing leaks. It may be finding the weakest link and pushing out of it.

they are new, replaced the crank hose and pcv while doing the first leak. they could have contributed to all the leaks, then again, nothing was blocked, so i dunno
