20v keep blowing turbo, help please

[quattro-nick]

where did you measured the oilpressure?
to much oilpressure will not damage the turbo!
only ballbearing turbo's need a ristrictor
maybe you have to little oilpressure on oilfeedline from the turbo
I suggest you to disassemble the oilfeedline on the turbo and put it in a bottle and start the engine and let it run for 3 seconds to see if you have enough oilflow

Was the engine warm when you shot the video? what oil are you using?

I'm not sure if it's normal for the pressure to go over 5bar as the std gauge only goes up to 5bar. Might be worth pulling the pressure relief valve spring to check that the piston moves freely or that a previous owner has not shimmed the spring to bump up pressure.

Hi all, i hope somebody can help. My 20v aby keep eating turbos like sausages for breakfast , 3 and counting. First standard s2, then volvo k24 setup and now k27 hybrid. All happened within 100-150miles. Basically after you floor it, turbo start making noise as it's blades touching walls. It went for rebuild, hot side seals was blown and bearing eaten. After installing new one same happened for k27, turbo still in the car but it's gone, start sweating oil through hot side and oily whit smoke. I have no idea what it is apart from that is something wrong with oil pressure, i plugged mechanical oil pressure today thinking that there will be none, but now i'm thinking maybe it's to high! Maybe some restrictor needed for turbo feed line?
There is a video
