took off the intercooler and poured out about nearly half cup or oil.
Easy fix or is it my turbo thats shot. Car has 16x thousand miles

Pretty normal.
Its when your oil level starts dropping like a rock that you need to worry. Half a cup isn't much.

LOL really?
My car (with original turbo) has 355,000 miles and it does the same thing. I build up an ounce of oil per 1K miles driven, and drain the intercooler about every 3K or so just to keep and eye on it and make sure it doesn't build up. Babying the car will build up slightly more oil than keeping it running at a normal rpm range and shifting at 2,400 rpm to 3,100 rpm. Since having my car chipped with the RC2+, so it boosts at 18 psi now (instead of the stock 11 psi), it has built up a lot less oil than it used to.took off the intercooler and poured out about nearly half cup or oil.

As long as it is sealed and can withstand the pressure from boost (which isn't much in all reality on a stock TDI) should be just fine. Yes that makes sense and then you don't have to pull the tubing apart and jack it all up to "pour out" the oil.I was thinking last night of drilling a hole in the bottom of the intercooler, taping it for 1/8" NPT and putting a plug. Would make it easier to drain vs removing it.
Make any sense?
Probably a lot better than my idea, which would have been to simply drill a tiny (.010 or less) hole at the lowest point and let the boost blow it out. But that would make a mess as well as put an oil slick on a drive wheel, so I haven't. But your idea would work. Sounds good to me, anyway....Make any sense?
Blow-by and all the oil spraying inside the engine creates a condition that oil becomes atomized like a cloud (mist) and is sucked thru the ventilation system via the air intake system.......
Yes, the oil mist comes out of the Crankcase Ventilation System on top of the Valve Cover pan (top of engine)..............goes into the suction side of the intake system! Look at the air filter box....follow the black round corrigated pipe over behind the Intake Manifold....notice the connection from the smaller pipe coming off the Valve pan?So your saying that I should find oil residue on the air intake side of the turbo? I havent looked but would be the first ive seen. But Ive only seen turbo diesel truck stuff.
An occasional "Italian tune-up" will blow out most of the oil that would otherwise collect in the intercooler. Most of us have never had to drain oil from that location.So your saying that I should find oil residue on the air intake side of the turbo? I havent looked but would be the first ive seen. But Ive only seen turbo diesel truck stuff.
The MK1 VWs (early model VW diesels) with or without Turbos, were notorious for dumping oil into the Intake System........ there was actually a recall on the 1.5 engines to added a vent pipe from the front side of the engine off the Vacuum Pump plumbing to deal with blow-by mist! Didn't help much!If you want to fix the problem at the source, you can install an oil catch can in line between the PCV and the intake (suction) side. I am looking at a unit from 42 something or another. (I will edit post with real name).
All boosted applications (That I know of) suffer from this. Ford Lightnings where terrible about it, but seeing as how they used a H20/Air IC, cleaning it involved pulling the blower off the truck, huge PITA.
Oil catch cans are the way to go. Not a perfect solution, a powerstroke owner installed one, after 40,000 there was no signs of oil in his cleaned out intercooler. I just cleaned out my intercooler, when I get a Oil Catch Can, I'll clean out all the hoses too.
Drive the car properly and you won't have oil in the intercooler...seriously!took off the intercooler and poured out about nearly half cup or oil.

Just the tubes that attach to the intercooler with clamps. They might be a bit stubborn to get off.What's the best way to check for oil in the intercooler? I tried pulling apart the hard plastic tubing that goes to the intercooler but couldn't get them apart...am I looking in the right place?
I agree and I never get more than a half a cup of oil when I change the timing belt. I can't believe you have to maintain it much more than that. 240K miles...Drive the car properly and you won't have oil in the intercooler...seriously!
You are lugging the car around, failing to get on boost, short shifting and KILLING THE ENGINE in the process.
You Need to be shifting at 2500 when cold and around 3000 when warm.
Short shifting a TDI WILL ABSOLUTELY result in damage to the cylinder and lower compression, higher oil consumption, poorer fuel economy and eventually an engine that has compression below wear limits.
If you want to clean an intercooler out, FLOOR THE CAR!
Why do you think you need to check for oil in the intercooler? If you think there is some, then you can blow it out with an occasional Italian tune-up -- which is a good idea anyway.What's the best way to check for oil in the intercooler?
