T-Good

New to the world of Audi, I just bought a 98 A4 1.8t, ran good for the first week then I got a #1 cylinder misfire, replaced plugs and coils all 4, that remedied that issue, now I'm blowing thick white smoke, no oil or coolant mixing, car drives but doesn't have much git up n go, did a compression test and reading 100psi on all 4 cylinders, I know thats low and I'm planning on getting a different tester to make sure. oil level is lower today than it was saturday so I was thinking it may a bad turbo. Any input would be helpful

From what you have described, sounds like you have a blown turbo. It needs to be replaced. Same thing happened when my turbo failed, had thick white smoke because coolant was getting into the combustion chamber from the turbo.

Hmmmm coolant doesnt get through a bad turbo, oil does. So your saying you turned off the car, put coils and plugs in, and started it, and now it smokes like crazy? How much have you drivin it since? How long did it sit waiting to be fixed? With that low of compression id be afraid of it just being worn out.
