Re: Sludge in coolant, high pressure
A quick way to determine if you have coolant in your oil, although this will be harder with your intake and a head removed...
Run the engine until it's at temp, and the exhaust manifolds are HOT. Pull the dipstick and let a few drops of oil land on the exhaust manifold. If you only have oil there, it will just sit and smoke, but if there's water/coolant in the oil, it will sizzle and boil til the liquid is evaporated. It's truly amazing what you can remember from high school auto shop some 40+ years ago. Just don't ask me about day before yesterday!LOL!

Re: Sludge in coolant, high pressure
Through the years I worked in the garage we just put the vehicle in a bay let it sit for a while then drain the oil. If theres water/coolant in the oil then it will come out before the oil. Easy to spot that way.
