I believe this is the intercooler tube, is it common to find oil in here?<p><IMG SRC="http://www.icstew.com/v70R/tube_oil.jpg" BORDER="0"><p>

Re: Oil in intercooler tubing? (83caddy16v)

Eastern Aerospace has a kit to re-route the plumbing for the pressurized air between the turbo and the throttle body. their path makes much more sense to me--which made me wonder why the heck the Volvo engineers did it the way they did...<p>so i posted my question and somebody came up with a logical reason--oil leaking from the turbo seal gets into the pressurized air plumbing leading to the intercooler, so Volvo routed the pipe over and then down into the bottom of the intercooler (to let the oil mist cool and collect at a low point??) rather than forcing it into the top and having it coat the entire inside surfaces of the heat exchanger...<p>...i suppose that's as good a reason as any...still, if you look at the EA kit you have to wonder--it's clean and simple--logical. how bad would it be to flush your intercooler with kerosene once and a while? after all, cleaning the throttle body is a regular maintenence item.<p>anyway it's hard to imagine an oil seal being capable of completely stopping any oil from getting into the airway...and still keep the bearings properly lubricated...so i'm guessing that everbody with a turbo has a slippery airpipe and greazy intercooler innards.<p>...have you ever heard a turbo bearing go dry? <p>...we're talking ~100,000 rpm or thereabouts <p><br>...so we er' on the side of too much oil...<p>check IPD...they have a kit to fix the leaking oil from your turbo drain pipe seal. <br>

It's normal to have a tiny little bit of oil in the pipe. Had it in my 854T and my Legacy B4 also has a tiny little bit of oil in the intercooler pipe.<br>
