Hello all BMW turbo specialists!
I have a problem on my 1980 M102, no boost at all.
On my boost gauge, I can read vaccum at idle, but only 0bars at full throttle.
I read a lot of topics here but not found any solutions
I have measured turbo play: axial play 0.05mm, and radial play 0.5mm, so it's correct.
The turbine turn correctly and wheels are in good conditions.
I have search for leaks and found a cracked hose (n°11631273055) but no effect after new one installed.
I took the compressions and they are good (9, 8.5, 9, 8.75, 9 and 9)
The ignition timing is correct (12° at idle and 34° at 2000rpm).
I don't know where to look, does anyone have an idea?
thank you very much
