M235i Squeal And Whistle Noise HELP NEEDED.
Hi,
I have recently purchased a 2016 BMW M235i N55 on 52000 miles. Shortly after purchasing, I started noticing a squealing/whistle noise at idle constantly and 3-4sec after I switched off the engine like the video attached. https://youtube.com/shorts/Afseh8OkaO0 http://https://youtube.com/shorts/YjfpQyiyzNY Since Finding the Noise I have replaced the PCV Valve Cover and Gasket and the squeal still persists. However, to add to the problem I have noticed a massive oil leak from the round back of the engine and gearbox could this mean the PCV Eventually broke the rear main seal? FYI 1 Litre of Oil from 500-600 miles. SOMEONE, PLEASE HELP IM A WITS END WITH IT. |

I'm having issues identifying the sound you are referring to.
The ticking noise is reminiscent of every N55 I've heard. I'm not hearing the squealing you're referring to. I did find this post: https://www.e90post.com/forums/showthread.php?t=1197666 Which provided clips that have a much more obvious screeching. Do you think it sounds similar to these clips? It seems unlikely it's the PCV, considering you changed the entire valve cover already. Typically, when I hear screeching, I think accessory belt and tensioner. Though, the oil leak indicates a separate issue. |
Appreciate
