Got a '00 1.8T (Engine Code ATW), and have been using oil for some time (since switching to synthetic), and finally had some time to record how much (about 1/2 quart for 800 miles, so below the "accepted VW rate of 1 qt/1000 miles, which I've NEVER had in any engine, even my crappy old Ford Escorts!!!) Well, while trying to diagnose a P0411 issue with the Secondary Air Pump, I noticed a trace of oil from the turbo outlet down to the Plastic pipe that runs across the front of the car to the Intercooler. Well, I also noticed that the valve cover gasket is leaking so at first attributed it to that, since I didn't see any sign of oil in the Throttle Body. Was digging around some more today, and decided just for giggles to pull off the rubber hose at the bottom of the Intercooler, and my worst fears were confirmed, there was some black oil pooled there in the bottom of the intercooler, leading me to believe the internal oil seal is shot on the Turbo. The car has 96,000 miles on it, and I'm pretty sure without talking to the dealer, that they will say that oil usage is "normal". Well, sorry, oil being burned by the rings a bit might be "normal" and the worn valve cover gasket doesn't bother me so much, but a major engine component shouldn't be losing oil like this. So, by VW's definition it is not "bad" yet, but the 100k PT Warranty is fast approaching, and I don't want to wait till it fails before replacing it when rightfully it is on its way to failure now and should be replaced NOW. How can I go about preventing this. By getting them to diagnose it now, and then going back to fight them after the 100K PT expires, or what? What are my options? Any suggestions greatly appreciated.

"Some" oil in your charge pipes is normal, it usually comes from the PCV system and not the turbo. If the car is still under waranty I would give the dealer a shot and see what they will cover, cant hurt can it? If not you may want to replace that valve cover gasket and do your PCV system before jumping into replaceing the turbo there is a good PCV write up in the info section and "search" will yeild plenty of info.

Vista cruiser,
I got about the equivalent of a half-dollar coin (1 1/2-2 inches in diamater) on the pavement when I pulled the pipe. I do plan on having the dealer check it over though. At least then it is documented in case I have to fight them later. I'll definitely check out the PCV system though. I've got the valve cover gasket, but from reading the warranty pamphlet, am wondering if that is covered under the PT warranty since it mentions seals, gaskets, etc... I'll ask Monday when I talk to them.

Well, I don't think my PCV System is the culprit. Figuring that if any oil is blowing by the PCV Valve, it must also end up in the Pressure Regulation Valve (the "Puck" on the Intake Hose of the Turbo), but it is pretty dry, just a dry flakey residue, certainly not wet in any way close enough to be related to the puddle of oil that came out when I pulled the Connection Hose on the bottom of the Intercooler. So, looks like I go talk to the dealer about diagnosing it, and what I've looked at so far.

That amount would be completely normal, I would imagine your valve cover gasket to be the culprit of your oil lose.

Man, I hope (and PRAY) that you're right, cause I'll find a way to dump the car before I'll put that much money into it (I love my car, but for a turbo to go with under a 100k miles is not a way of telling me to keep the car) I just talked to the dealer, and the warranty specialist there told me she didn't "think" a shot turbo would be covered under warranty, so I'll be VERY happy if they tell me it's the valve cover or PCV system. I can handle that!

Oil in the intake hose is normal, even the amount you describe. Since the oil issue starting with the switch to syn,try a different syn oil or a thicker one.

PZ, I already did that, when I went from 0W40 to 5W40, but that is as far as I can go without going out of the viscosity range we're allowed. I wouldn't think changing to another oil type would make a difference, although it's hard enough even finding the oil that meets the spec in the supplement now. I'm going in Wed to have the geniuses at the local dealer take a stab at it. If they come back and tell me it's the valve cover, I've got that covered with a spare seal and will do the work myself. It it goes deeper than that, then we'll take it from there. I do feel a little better though that you guys have chimed in and said that the oil in the intake pipe is normal. I'm more curious now than anything since I don't see any signs of oil in the PCV System, and it doesn't LOOK like I'm losing almost a quart every 1000 miles from the moisture around the valve cover, BUT....

Gregu710,

I and several others have resolved excess oil consumption by using Auto-Rx. At 100k I was using a quart every 1000-1500 miles. I did the Auto-Rx treatment and I now use a quart about every 5000 miles (I'm at 123k now). Smoothness and performance are up noticably.

Another guy in NYC on the forum was burning oil like mad, a quart every 500 miles and blue smoke on accel and decel and on on startup. I had him do the ARX and he went to a quart every 2500 miles and no smoke.

It's worth a try and can't hurt anything. The theory is that the ringpacks may be sludged, the valve guide seals have crud and have lost some elasticity and sealing. ARX addresses these issues.

well, just got the word from VW, the Turbo is leaking internally. So now begins the battle (possibly) with VWoA to get it covered under warranty. I have 4000 miles left in the powertrain warranty, but of course, our friends at VWoA want ironclad proof of oil changes (which I have documented faithfully in the maintenance record, but of course don't have every receipt for every oil filter over the past 3 years (since the first 2 years were covered by VW). If they come back and say "ney" to warranty coverage, then I will politely tell them where to stick their turbo, and put it off until I can do it myself (or put it off until I can dump the car back on them or another VW dealer!!)

Hey you can have mine. My turbo seems to be fine, i'm leaking coolant into my oil. So if we combine the two f.... up engines, we'll have a perfectly working one.
Check my thread about coolant in my oil!!!???
I'm starting to really dislike vw and i've been a devoted vw fan since my first car. But the 1.8T is a piece of ....

You know, I LOVE how solid my car is, the feel of the suspension and steering and the pickup of the engine, and the look of the car. It is comfortable on long trips, does OK on gas (especially on the interstate at 70mph), and is all-around very solid! BUT!!!!! I dislike losing sleep wondering if VWoA will stand behind it's product via the warranty, when by all rights it should. What if I had fuel injection problems? Would anybody be expected to provide receipts for all of their gas purchases proving that they bought only premium high-octane fuel? I think NOT!!! I dislike the fact that for almost 55,000 of the last 96,000 miles, I've had the Emissions Workshop warning on for various reasons. I dislike that I've had to put in a new Throttlebody on a car with only about 70000 miles at $600+!!! Or the fact that 3 of my 4 doors have the fabric pulling away from the backing on the door, just like my old POS Audi 5000 did! Or that I had to put a SAIP in because the Combi Valve was defective, neither under warranty! Or the vacuum check valves that have dissolved into thin air! My only regret is that this happened (with the turbo) AFTER I was foolish enough to buy a Beetle for my wife and not before. At least I would have then had some leverage or would have thought twice and maybe bought her a Mini instead. Needless to say right now I'm fuming and waiting for the call from the stealership, "I'm sorry sir, VWoA has decided not to stand behind their product!"

well, as expected, I got a call from VWoA, and talked to the dealership, and they don't believe it will be covered because I am not using enough oil and because I don't have every receipt since the day I bought the car (that will change, oh yes, that will change!) The Warranty Claims manager did hold out some SLIM hope that the Regional Warranty Claims rep who is visiting the dealership on Monday may offer to cover it, but I'm not even going to get my hopes up. I'll replace the valve cover gasket, and see how my oil consumption changes, and when I can afford it at some time in the future, will replace the K03 with a K04 on my own (unless I win the lottery at which point I will dump the car and start fresh!)
