Hi everyone let me start off by saying this post is to inform/warn existing and or potential F30 owners about their N55's. I own an e92 m3 and not a F30 but I thought many would want to know...
I was at my local dealer having the oil on my gf x3 i35 changed and I see the bottom half of a N55 removed
....
I asked the tech and he explained the customer had been complaining about a clicking sound only when the engine was hot and up to temp.
After 30+ hours of trouble shooting it was determined that the crank and main rod bearings were failing and needed to be replaced. Puma case was opened and work began.
I was surprised to see the amount of wear on the shells, car has 13,000kms.
Anyways if anyone has questions or a click sound coming from their engine might want to have it looked at!!
Thanks
Alex
