So I have drained all fluids getting ready to replace them and fire her up soon and I have discovered oil in the readiator fluid. So I drained the oil and it was dark but no Water in it. I am looking for answers to what may have caused this:
Bad radiator
bad gaskets
bad something???

I am not as worried as I was with my truck (water in the oil pan and oil in the radiator) because of no sign of water in the oil pan.

So, any takers on giving an explanation???
