Big oil leak shortly after egr delete and new oil cooler

[dlowkes]

Ok so I did my egr delete and new updated oil cooler, with all new gaskets. The truck fired right up and drove better than ever, NO LEAKS. Drove a total of 84 miles over two days beating the crap out of the truck, not a hiccup. Plugged the block heater in that night. Went out the next morning to start it (23*f) started awesome no white smoke. Went inside for 4 minutes, come out to see a 1.5ft puddle of oil under the truck, coming from the valley/back of the block.

Can't really see where it was coming from. Turbo, air filter and degas are already out of the truck.

Any ideas? ICP? My thought was if it was a gasket it would have leaked from the get go. Right? Lol just kind of hoping that I don't have to take the intake off again, but probably will end up with my luck.
Thanks Derek

Oil cooler cover, oil filter housing base, turbo drain tube, ipr, and icp if you have an 03 - early 04 MY. Usually turbo drain tube, after this kind of work, but normally right after startup.

Sent from my phone that somebody didn't help me get.

Oil drain tube and filter house are dry. I'll have to look better in the daylight
