Blown head?

[madsav]

Oil in the radiator ve been told = blown head gasket, but now im confused as when i flushed the radiator it was like a choc sunday even the reserve was covered in sludge,but the motor sounds fine seems to run fine and got 165psi per cyl on a compression test any thoughts on how or why there is oil in the radiator?

Sounds like the intake manifold gaskets are blown/leaking, common fault with the ecotech engines
