So I have a stage 3 s4 with bw k04 turbos and I just had to replace the center sections of them because the nut on the compressor side came off the driver side turbo and broken the shaft off and it dumped like 3/4 of the oil out the exhaust pipe. So I got the motor all back in and it still burns oil out the tail pipe now it's blue smoke mainly when I accelerate hard and then when I idle after a pull it will smoke whitish gray so I'm assuming it the hot exhaust burning off the rest of the oil the engine didn't burn. So my question is what the blank is going on I have silicon Pcv lines could the pancake calve be the problem? Or really bad valve seals I know my compression is good so it's not rings or head gasket or could it still be a head gasket? No water in the oil or vise versa

Are you using oil as measured on the dipstick? If not, I have a hunch that the oil could be left over from before and is in you cats/exhaust system. Maybe pour a can of lacquer thinner in the gas to try to clean out the cats and exhaust. Drive it hard to try to blow all the oil out.

If you are using oil measured on dipstick, could be valve seals or gasket. I would check your plugs, to find cylinder with leak or rule out seals and gasket.

Well I drove it hard yesterday and it was smoking real bad like leaving clouds that hang and then a half mile from home one more hard pull and all the sudden there was a loud pop like something broke and it wouldn't accelerate at all and then it shut off had to unplug the maf to get it to drive the last 1/4 mile home when I pulled it in the garage it sounded like something in the short block is clanking around at idle si now it looks like I'll be needing a new engine well new to me at least fml
