OK so it's kinda a long story.... I bout this car a month ago. Everything was good. I have a 97 a4 B5 with the 1.8t AEB motor 5 spd quattro. After driving for about a week I noticed the "dentist drill" coming from my stock k03. But before I changed my turbo I put a fmic on. As soon as I took it for a test drive it was a foggy show behind me. So I changed my k03 and went with the k04. Installed the new turbo hoping it would fix my issue. It did not. It does not smoke on start up nor does it smoke while idling. It smokes the most when I change gears and in 3rd and 4th. Also smokes when I am coming to a stop. I know it's coming from my exhaust. That much is certain. With the bad k03 I went through 2 qrts in a day of daily driving. But with the k04 I have been driving for 4 days and I have Used maybe a quart. It's just smoking like crazy. Just need some help. I'm new to the Audi world. Hahaha all help is greatly appreciated. Also car does have 209k unfortunately

Did you notice oil residue in your exhaust ports on your cylinder head when you swapped the turbo? Or can't remember?

Could be the placebo effect, but I'm thinking you may have a compromised valve stem seal if not the turbo. Labor is pretty extensive, though. It would require you to remove both cams (TB and components would need to be replaced), lifters, valve springs and retainers. At that point, you can take the seals off and replace them. Not really a job for the faint of heart. And that is only assuming that is your issue.

Do a leak down test: https://mobiloil.com/en/article/car-maintenance/car-maintenance-archive/how-to-do-a-leakdown-test

Well when I took the header off it was saturated in oil. It was the normal carbon look for A car with high miles. It just doesn't make sense how it doesn't smoke at idle. Even if I rev it up just siting. Nothing. But under load and it smokes

My apologies. It WAS NOT saturated in oil

Do a leak down test. At least then you can cancel out variables (important), along with confirming if it is a cylinder issue or not. If your cylinders are fine (what the leak down test will confirm or not), then focus on your turbo and oil lines.

Another thing can be an emission issue (that spaghetti under your intake manifold). To check this you simply undo the bottom hose on your intercooler (if running an SMIC). There should be "some" oil. But if you have a lot, then that is most likely your issue. What happens is the oil making it's way from there into the combustion chamber, causing the smoke.

Just throwing out ideas, but they are all credible.

Well I have a fmic. But when I did the switch. There was quite a bit of oil in my smic. Like I said I'm new to the Audi world and I guess I didn't think too much of it.

A handful is normal. Take off the hose on the outlet and see how much comes out. If like a quart comes out, that's an issue. But helps in your cause. Because at that point it is a simple fix.

If a lot comes out what would it be? And do I take the inlet off the pressure casing or the intake manifold? Probably a stupid question I just wanna be doing it right

Check lowest points where it would puddle.

Possible bad pcv and prv.

I have read that ppl have just removed the PCV and dumped it on the ground. Is that possible?
