Question about cleaning coolant out of oil passages!

If you are still getting foamy coffee colored gunk, then you still have anti-freeze and water in the oil, no doubt. It does not take much to produce a noticeable level of foam. The issue of course is that it tends to highly aerate the oil and so it is not a trusty lube anymore.

To get as much as you can out, I would drop the pan and clean up everything I could see and touch with paper towels. Then take off the valve covers and clean it all out. This is the only quick way to get a bunch out that I know.

I would personally keep changing oil and filters after warming it up with each fresh change 'til it clears up more. Get some cheap Walmart oil and just keep running it through. MMOil and ATF additions won't really do anything special to absorb water to help get it out; physical removal by hand and repeated flushing with oils are the one ways I know of. I have done this on a trannie that got water in it and it took 4 fresh fluid cycles to clear it up, and it was not a lot of water in that case.

Can't tell you if you still have a leak. That is the reason that I would be aggressive in physical cleaning and repeated flushings at this point; if you do not get the crap out, then you have no way to tell of you have a new leak.

If you want to check in the cylinders for water, then pull the plugs and feed in a section of cotton rope in each cylinder one at a time and compress it gently and then pull and examine for anti-freeze. Also, if you run the car for a bit, does the water vapor normal for a cold start clear up after a bit?
