Oil In My Water- R34 Rb25det

[Space Goat]

hi...

im in the middle of doing a r34 rb25det and come across bad news... i ran the motor up in the car for about twenty five minutes... after about 15 mins when it got nice and warm it started coughing out white smoke... i kept running the motor as i was told the turbo was "smokey" coz the car i got it out of had been rolled over...it kept up the coughing for another ten minutes then i turned it off... as soon as i turned it off i checked the motors vitals... the oil... no problem... but the water was oily, not emulsified but you could see little bubbles floating around and it felt oily between my fingers... anyone has this before... ive been told that they are known to crack blocks so thats my main concern... ive taken the oil cooler off and will send it away to get pressure tested in the new year... i will also run it with fresh water and the oil cooler bypassed... if not its off with the head after a pressure test... should the block be cracked in goes a rb30det neo... that sorta rolls off the tongue doesnt it

just wondering if anyone knew any other small things to check before i commit to pulling off the head

thanks in advance and ave a gud x mas

Head gasket (maybe)

Id deffinately check this though if you have oil in water youd think you would have water in the oil... Its not possible the radiator is just full of filth and needs a good flush?

nar its a brand spanker radiator and when i got the motor off i took off the water pump and flushed the galleries... yeh JDFNG im praying for the headgasket if its not the oil cooler... the turbo isnt water and oil cooled is it???

what was the smell of the smoke like? if the headgasket is gone it can leak water into the head.

pull all the spark plugs out and look for signs of water in the cylinder and on the spark plugs.
