Hey guys, having a bit of an issue in regards to smoke. It blows a thick amount of smoke only above 4.5k rpm, on and off boost. Story goes the car blew a small amount of smoke, the oil was changed then started blowing smoke. Ive tried a thicker oil and even an additive just to check if the oil needed to be thicker, has a td04 which i replaced the seals in aswell. After countless people telling me turbo is blown, ive tried a 3rd td04l and a new oil line, disconnected water lines and still blows the same smoke. Compression is relatively high (170-180) accross all 4, and still smokes with the turbo disconnected from the intake.
Any suggestion is helpful at this point!
