Bitter taste of defeat! So much coolant in the oil pan.

I had a similar mystery leak but it was external. It was weeping out of bolt hole. I tried about everything. Finally I changed timing covers and it fixed it. The damn timing cover has a very hard to see hairline crack in it from a casting flaw. If it's leaking this much antifreeze it should be very obvious where it's coming from. After reading all 3 pages, I'm thinking all along... Pull the pan and see.
