From videos I have watched on youtube, I should be good. Vanes spins free but no in or out play. I did not check my intercooler, but will do. ......Before I put it back together, looking an excuse to buy the BHW manifold and turbo. Just say I buy a new manifold and turbo, I already have a stage 1 tune, do I really need to have it tuned again?Describe the amount of oil. Oil in the charge pipe system is 100% common with thrust bearing turbos. There will be up and down play in thrust bearing turbos. There should be no in or out play. You can measure run out but usually if the play is enough so blades don't hit the housing you are good.
If I dumped my passat intercooler id find maybe a cup of oil in the bottom of it. My boat, excursion and passat are all factory turbos and all have oily intake systems.
