Engine Stalled, Rough Idle And Knocking Noise On Startup
Hi everyone,
I am going to give as much info as possible. I have a 2014 Subaru BRZ A/T with 87k miles. Mods are Skunk2 Catless EL headers, Stage 2+ OFT tune, Greddy SP Elite Axleback headers. The headers and tune were done literally a week before this happened. It was driving fine all week until this happened: I was driving on Friday, I had to do a 2 point turn, when I came to a complete stop to do the turn, the engine stalled. I turned the car off but it would not turn back on it would try but wouldn't turn over, got a boost from my moms car and my friends car and nothing. Took the battery and alternator out, got them tested at two different parts stores, they both were good, nothing was wrong with them. Although Pep Boys told me the battery was low on charge. I put them back in the car and tried to turn it on. It struggled to start but finally turned over. It sounds super super rough though. Here is the video of when it started after I put the alternator and battery back in: https://www.youtube.com/watch?v=Yz8O4XW4CBA A lot of the guys on Facebook groups are telling me my engine is done. I dont know how I didn't do anything to warrant a failed engine. Honestly since the pandemic started I haven't even been driving much. Thanks in advance for any and all help. I am literally praying my engine isn't finished. |
Definitely sound like a trash motor. Pull the dip stick and check for glitter or water.
You hit a puddle recently? Or forget to change your oil for 20k miles? Also, with the rpms fluctuating and all that noise if it were anything external you would be hard pressed to miss it on a quick visual inspection. |
Definitely sounds like it’s knocking, hate to see that for you. My 65k 2014 motor did the same seemingly out of no where. I paid a dealer a diag fee who wanted to tear it down to confirm failure but at that point I knew to replace.
Here’s what I did to replace it: Search for an engine on car-part.com You’ll want to find: An engine from the same model year/transmission An engine with no cracks, tested, warranty, and ideally provides a core refund plus the cost of picking up the core included. When my 2014 started knocking (non recall related) I paid about $2500 for the motor and another $2000 having a local performance shop do the engine swap. |
That almost sounds like it could be something on the accessory belt. I wouldn't run it anymore though until you figure it out in case it is internal. I don't see any CEL though..

Sounds to me like a Ford Model T running.
I'll go with something to do with the belt theory. I suggest you take the belt off and fire it up for a moment to see if the sound is still there. I hope it's minor. |

Hey everyone, I brought the car to a shop today, they told me the engine is blown and I need to get a new one. Super bummed, but thank you all for your help I really appreciate it. Not sure what Im going to do now
