Engine howl, whine, shake, hesitation then limp mode
So this happened today on my way to get my inspection
Car is a 2011 328i RWD E91 AT with 100K on the clock. Driving along smoothly with no issues and started to hear a little whine coming from the engine. At first I thought it was the blower motor which happened in my e46 and was an easy fix, but it got louder and louder until at a stop light it started to shake and hesitate. pulled over and stopped the engine. popped the hood and no smoking nor oil spill, to be safe I decided to skip the inspection and just head back home. just before getting home I got the check engine light and went on limp mode, engine still howling. pulled in the garage now I can hear the engine rattle so I went and checked the codes. Codes: 2A87 2A7A I did a search for similar scenarios and found out it could be the valve cover CCV so decided to replace it since I have one in stock, planned to do pre-emptive maintenance and checked what else is the matter. Valve cover off and found the following to my dismay. INTAKE SIDE EXHAUST SIDE Tried finding those bolt heads but cant see anything from the top. Does this mean I will have to tear down the entire timing belt area? Is it a lost cause? |

Drain the oil/put a magnet in the drain hole/pull the pain and see if they came out. I believe I've seen people pull them out of the pan before during oil changes or oil pan gasket

There was a recall on these bolts on some engines, not sure which exactly as it wasn't N54 which I have.
