So I did CCV, OFH and Hard Pipe job.
I smoke tested and no leaks, but when I went to crank the engine it starts then make this weird schreeching sound and dies immediately. I rebuilt the disa, previous owner bought a topran shit, but it doesn’t hold vacuum. Should I replace with an original BMW one?
I'm currently doing the famous CCV job and I need an advice.
I recently did my cooling system, but I'm replacing the thermostat and the water pump for hopefully better quality.
I will also replace the alternator while in there and maybe power steering lines and housing later.
I already removed the manifold, waiting for parts to arrive.
Edit: Sorry for the blurry images, I forgot to switch screen to take screenshots.
