Help! serious noise from 2.5 turbo engine (see vid)

Postby Blue GTSpecB » Sat Jul 23, 2016 3:01 pm

Hi all. Was driving home last night and engine started making a knocking noise. I was 1/2 km from home so risked it but by the time I got home it was pretty loud. I started it once again this morning for the video and it sounds the same. No engine light or low oil light. Car is a stock 2008 GT Spec B auto. Anyone have an idea what the noise is. I'm guessing it's serious - cheers

Apologies about the squeal in the video - that's my phone but not risking starting the engine again.

Sorry to say, but that sounds like big end bearing failure.

I seem to recall mention of a bad batch of 08 engines that suffered big end bearing failures. You can check with Subaru to see if yours is in the affected batch (after confirming it is the big end of course) and go from there? I think some people were able to claim warranty on the repairs still.

How many K's on the car?

Does not sound good at all, agree with satogixxer here it sounds like your engine is rooted

Check the build date of your car, if it is between Jan and April 2008 it is in the affected batch and I'd give your dealer a call.

I didn't when I had my original engine die and I definitely would knowing what I do now. I believe a few people have taken this to Subaru and had deals where they only pay for labour and Subaru pays for the parts and things like that even though they are long out of warranty since it was a known issue.

On the plus side it is still stock so there'd be no chance of blaming any mods or tunes etc. that might have been done

Hey, any update on what Subaru came back to you with? I have the same issue that presented itself just now and my build plate is 02/08.

So far the knock is only audible when revving but I didnt drive it far at all as soon as I noticed it so I guess its on its way out

Mine is also a 2008 Jan build GTB, 6mt wagon, and I lost a big end at 121k kms in late 2014. It was called in at 4k for its first oil change and checked for the big end issue, given the all clear. Went to dealer, they checked that ECU had not been tampered with, and had all required services, and with a bit of a push offered parts (new short block, gaskets, fluids) if I paid for labour, estimated at $2500, including sending heads out for a flush etc. I opted for a new oil cooler (you cant get metal debris out of a cooler!), and clutch, so all up it was a bit over $4k.
If your engine was in the bad batch, and you dont have high mileage, you have a good chance of getting some sympathy - not that its common from Suby dealers!
