If there was antifreeze in the coolant, be aware that it's all through the lubricating system, and will remain there to contaminate the next filling of oil even after you find and fix the source of the intermix. That's why I suggested doing a flush of the lube system before tearing the engine down to the point it can't be run. Getting antifreeze contamination out needs to be done sooner, rather than later.
