2000 S80 T6 - What is this (valve?) called?

[Bluevanacd2005]

I have what I think to be a valve dripping oil on top of my engine... it is between the inlet to the turbos and air filter, and comes from the oil seperator box. I attached a picture of it (microsoft word format), but cannot figure out what its actually called.

Thanks,

Spenser

It is a heated nipple where the oil containing vapor hose meets the incoming fresh air hose from air cleaner to turbos.
More than likely the grommet where nipple inserts into turbo air pipe is the leak. That connector hose from metal vapor pipe to nipple has the split and that could contribute also.

Oh ok thanks. Thats interesting. I wonder if a burned out heating element would throw the CEL? Or what 'bad' things would happen to the oil vapors if they didn't get heated?

There is no diagnostics on that heater. It is there to assure that in subfreezing temps that the moist vapors from crankcase don't freeze and block the venting.
