noticed the other day that my rb25det has a little oil in the coolant, not enough to change the color of the coolant but i can notice it when its in a puddle on the ground.
It seems to have lost abit of power from when i bought ( 2weeks ago), it does have a coolant leak from the block ( not was whats the parts called but ordered a replace from nissan, 3 weeks away, also ordered a coolant temp sensor as it wont start first time without pumping the accelerator.
Car doesnt show no signs of over heating, just a slight bit of oil in coolant and loss of power?
