Its not a belt squeal, but it is about as loud. Much less rubbery, more metal/metal contact sounding. Its also coming from the back left of the engine bay, same corner as the turbo.


Once the engine is semi-warm it goes away while under power (not necessarily under boost) but will make its noise again when the gas is let off.

Makes me thing the rotella is too thick when cold and the oil pressure under 2k isnt enough. The turbo is being starved of oil. But its still only a 5w...
