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

And you may have the price of a new engine to gain - :) |

If the noise stops when the belt is not moving that usually means that something that the belt is driving has a bad bearing and that part needs to be fixed or replaced. I would start off suspecting the tensioner pully. |

Well, I'd ask the shop if they would loosen up the belt, just to satisfy your curiosity. If they won't do that, I'd ask them if it would be OK for you to loosen up the belt while it's at their shop. If not, I'd just drive it home and check it out. |

Also I love your username, believe it or not it’s always been a dream to see both of our characters have a crossover one day. Solid Snake vs Slade/Deathstroke. I feel like they are pretty similar. Of course that would never happen Quote:

Highly suggest not getting a replacement engine, new or used, through the dealership. Just take your time to find one on the internet, even if you have to drive a rental for the meantime. Dealer prices are absolutely bonkers. I'm talking about 13k for a new engine. That's how much a new block costs last time I've seen their pricing list. |

It sounds to me like a valve tappet is really lose, almost like the shim has escaped from underneath the bucket, although I don't know how that would be possible. Maybe something else in the valve train is whacked out. - :iono: |

I personally would have a hard time jumping to "blown engine" based solely upon that sound. |
Easiest for sure tell without dissembling the engine is have a used oil analysis done. They will be able to pick up the bearing material in the oil if that is what is going on, but that sounds pretty eff'd.
|
Gotta love the ol’, “my engine sounds like shit/knocks/ticks/etc.” threads, yet they keep starting it and running it, for what I don’t know. Like, maybe it’ll go away if they rev it long enough? Just fix itself?
|
Wasn’t what I was getting at, at all, but ok.

Thanks everyone for all the help. I have an appointment this Tuesday at the dealer, they will look at it. I'll fill you guys in.
|
Maybe try starting it some more in the meantime.

Hey so I had the car at the dealership for most of the week. It is certainly a bad engine. Subaru of America sent me the following message:
Dear Mr. Robin : I have thoroughly discussed with the retailer. At this time, given the situation and the fact that we have no maintenance records, we would not be in a position to assist out of goodwill from a manufacturer's prospective. To give you some context, I can only help by providing assistance towards a new engine (upward to $10000). The retailer may be able to find a new engine for $6000 or so but that comes with other questions that can increase that cost, ultimately. Even with the best POTENTIAL help I can provide, you are basically back to square one financially. Whereas I cannot provide assistance towards the repair, I would be happy to provide an incentive towards a new car of $500. -------- At this point I am not sure what to do. I can cut my losses, sell the car as is and just get into something else. Or I can see what an independent shop would charge me for a new engine and installation. The service advisor says I can get a used engine thats for $8000 and that we wouldn't even trust the integrity of the engine. It needs a short block, it needs heads etc etc. I think I'll cut my losses and just get out of this thing. They couldn't even tell me what the exact problem was. Just a lot of we think, we think, we think. What do you guys say? Open to advice. Thanks. |
If you own it free and clear and can be without it sell it private party. Some DIY'er will engine swap it or replace the engine. You will probably get a lot more then 500 bucks that way. @Opie

But you can also find a low mileage engine for 3k and have it installed for another $1000 I'm sure. |
Thanks for the responses, maybe its immature but I feel like selling it just because I am not happy with how Subaru treated me and do not want anything to do with them. Wah wah wah wah I know, Im a baby.
Theres a known Subaru performance shop a little bit under an hour from me, I called them, they told me they can rebuild mine for about 5k to rebuilt it though they would need to take it apart first to see everything that is needed which would cost about 2k alone, they can get me a used motor for about 4k and labor would be 2k. They actually have one in the shop that they are currently working on, that customer is at 6k so far. This sucks, this was my first car, I bought it and made the payments without any financial support from my parents. I just paid it off not too long ago and now I have nothing to show for it. But it is what it is. I have a friend who just lost her uncle to Covid-19, so when I look at it like that, I don't have it all that bad. Thank you all for the advice and all who helped me when I first started this thread. |
Buy a used engine from a reputable re-seller with a warranty. Buy some beer, invite your friends and swap the motor, problem solved.
Or I'll give you 1k for it as is...AT and I'd have to get it shipped to FL... |
