Or GAS! Oil with water in it looks like chocolate milk. Oil with gas in it is just thin. Sorry, but didn't notice what year truck you have. If it is carbed and has a mechanical fuel pump, then a bad diaphragm in the pump can let gas into the oil sump.

Good luck,

change the oil and filter first. and then remove the radiator cap and start the truck. do oyu have bubles in the radiator? air bubles i mean? if you do you have abad head gasket or cracked head. if you dont then the water is coming in from someplace else. how often have you had to refill the radiator? if never then the leak has just started or there isnt water in it at all. it could just be condensation.

it never got hot but i pulled the heads and hand um checked. and yup they was both warped. had um milled down and now all is fine..

what threw me was it never overheated at all.kinda odd..

Weak heads and oiling problems from worn cam bearings are the drawbacks of the 2.9.....
