4 days ago my car started getting hot and noticed the coolant level dropped slightly, checked the oil it was all clean. I thought it was a small leak from behind the waterpump. I put more coolant drove another 20 easy miles got hot again with a little dripping from the tail pail. Went to replaced the waterpump gaskets, and saw coolant behind the throttle body and inside the manifold. I checked the oil and is now contaminated with coolant, theres very thin white gunk underneath the valve cover.

Took the manifold off and the heads from the top looked normal. My thought is since the manifold has coolant without oi ( no white gunk oil and coolant misxed ) in it and it wasnt inmidiate how the coolant got into the oil, the source is up top and its flowing down slowly.

Anyone have any ideas to help out?

 

Blown headgasket,you don't need to find coolant in the oil to blow a gasket,most likely,radiator,thermostat caused the issue,change the headgaskets,check the heads and replace the cooling system components.

 

If it was a head gasket i dont think it would leak into the manifold without being mixed with oil. It would have pushed it with oil
Im not running a thermostat, putting in ls2 water pump right now

 

If you never did the throttle coolant bypass, possibly that line is leaking into the intake

 

I did, coolant bypassed already throttle body
