I want to hear everyones idea on how antifreeze can just run into the oil pan on an LS7 engine.
Brand new crate engine. Engine has been run for maybe 15 seconds total. With 6 quarts total in the motor. Upon start up oil overflowed the breather tank. Took the drainplug out of the motor and about a gallon and a half of anitfreeze came out before oil.
Anyone have any ideas?

its dry sump and I definately didn't add coolant to the dry sump resevoir. I am using petterson fluid system tanks for the oil and the coolant tank is 5 ft away from it.
Dont know if there is oil in the cooling system. Im not with the car right now so I cant check. The coolant is entering the oil so fast I dont think there is a way for oil to get into the cooling system.

I guess I will try to firgure this out tomorrow. I could only think of something major causing this. Cracked block or something with a head gasket is all I could think of.

Found out what it was. Another shop had this engine before us, and they had installed a cam and machined the heads to accept bigger valve springs. When they machined the heads they hit a coolant passage, which filled up the crankcase with coolant.![Bang Head](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_banghead.gif)
