My Pete rebuild

[Mr Hagg]

Several things turbo to leak. One being blowby. If you had a way to measure it under load Im willing to bet its extreme. Thereby not allowing the oil to return to oil pan from turbo like it should. Others being to low of a setting on turbo percent causing vacuum on intake. Air filter restriction. However, we know a few things here. One you are using oil and you have alot of blowby. With these things known Im betting this is the issue of oil... Also in my years of work getting a local shop to rebuild a head I have seen cases where all they did was clean it and rework valve seats. never replacing valve guides and a warn valve guide can cause exhaust and boost to enter the top of head under load causing massive blowby. I think once you have installed all new genuine parts you will be ok... Make sure to clock rings right too. You have a really nice truck and i know one day you will be able to enjoy it...
