Hi folks, after recently doing my M50 conversion my car had been running lumpy cutting out whilst I'm slowing down, also if I took the oil filler cap off the engine would cut out then make a loud woosh noise!
It was traced back to the oil pressure regulating valve/crank case vent. I've replaced it today and its cured the problem, I know on the standard 328i manifold its on a bracket and sits vertically, but as I have the M50 manifold mines lies horizontally under the manifold because I didn't make a bracket for it!
Can I just get rid of this and fit an oil catch can instead?
If I can't will it cause any problems with the way it is in a horizontal position??
I hope this makes sense...
