Oil and water mixing together

We have just pulled out gear box and fixed the reverse gear. but after putting it back together i found the radiator empty so i topped it up. i thought i had a leak in radiator so i put in more water. then i saw oil in the water in radiator so i checked dip stick and it is covered in water/oil. i drove it back for 200m and oil/water is spewing out the top of engine.

    no. you should be alright as long as you don't run the engine too long and cause it to overheat.

SOURCE: water on top of the pistons...

So you took the heads off as well? If you took the heads off and let sit over night condensation built up on pistons just wipe clean and install head gaskets and tighten to specs with new bolts. But if you took heads off and antifreeze come pouring out you have a bad head gasket change both sides. The reason it has not leaked into the oil pan yet, cause it has not gotten bad enough to do so. Believe its a mess.

This sounds like a blown cylinder had gasket. Although on some engines you will find core plugs below the rocker coverin the head.

From my experience, oil and water mixed together produces a muddy, inconsistent, frothy slime. So you need an additive the will open your oil passages back up, and help your oil pump build correct pressure. A product called "Seafoam" is ideal for this. Add 1 can of Seafoam oil and gas treatment to your oil (don't overfill). When your temperature stabilizes, change your oil again and add 1/2 can of seafoam this time. You should be OK.

Now, before get to work on your car, consider any other possibilities that may have occurred. Perhaps the car had blown a head gasket and now water from the cooling system is crossing into the oil return port in the head. This would make the oil on the dipstick appear exactly as if someone put coolant or water in the oil fill port.

Another possibility is a cracked head. Not the end of the car's useful life but definitely a few days in the shop. Same oil appearance as mistaking oil cap for coolant cap and blown head gasket.

OK, so lets diagnose: Let the car cool down completely. Remove the radiator cap. Start the car and carefully observe the water in the in radiator or coolant reservoir.. I say carefully because the coolant can suddenly Kick up in your face, especially if the separations between oil, water, combustion chambers has been been breached. If you see bubbles or a splashing of water out of the radiator, then you'll have to deal with servicing the engine heads. Hope this helps, remember to keep the kids back from the car, wear safety goggles and gloves, don't get in a hurry, keep a log of what you do and in what order, and make sure the engine is cool. It should take no more than 30 seconds to make this initial diagnosis.

Water and oil mixes together

Check oil by draining. Trans tank on radiator bottom may be oily slick you see if oil pan drained clean. Then trans is probably contaminated with antifreeze and that's what is mixing.

Crack in head passages could link oil and water, if you verify antifreeze and oil mixed in oil pan.

If no external leak and the transmission fluid colour looks white, the problem belongs to the automatic gearbox oil cooler. The oil cooler has broke mixing the gearbox oil and coolant causing this milkshake. It's a small radiator core type oil / water heat exchanger. It is cracked inside and transmission oil is mixed with engine coolant. Because the transmission oil pressure is greater than engine coolant pressure, the transmission fluid level drops. See also the coolant colour inside recovery coolant reservoir inder bonnet! It could be like this:

In the picture above the transmission oil pan was removed for oil filter replacement.

Oil in coolant.had head gasket done.but the problems still ther

either you havent flushed the cooling system out properly ,or the oil cooler has packed up ,their is a oil cooler radiator of sorts that the oil filter screws onto ,these often leak ,just remove the water pipes and join them together with a small piece of copper pipe ,then if you see oil coming out of the water pipes fit a new cooler

Oil in overflow of radiator.

If you have coolant mixed in you oil you have blown a head gasket at the very least. You will have to pull the heads and replace the gasket.
