95 subaru wrx engine knocking noise

[Guest]

i was wondering if some one could help me, i was driving along the motor way and my car started surging i pulled over and it died, started it up again and a knocking noise came from the engine left if for a few days started it again knocking was still there then car died.

Please help

Hate to say it mate but sounds like a big end bearing

unfortunately Drunkenmonkey might be right. Interesting part i realised: Do all cars usually die/stall and once started again, knocking will begin. True or false?

[Drunkenmonkey]

Knocking will always be there once a bearing is done

Oh yea i knew that...its the stalling/engine dying that buzzes me out. As above..will the engine usually die before knocking begins?

[Drunkenmonkey]

Um possible that the knock sensor picks it up first but knock should come first i think

It depends how it goes. Mine seized when the bearing went - ~7500 rpm to none in the blink of an eye.

Interesting.. :-\ So the engine must die when the bearing fully sh!ts itself..

And to everyone thats reading this and had a BEB. Did your engine die/stall/seize before BEB knock?

This should figure out my mystery question lol. sorry guys im just REAL REAL bored!!!

The folks watching me go past said they heard the death rattle. I couldn't hear it and seconds later it was all over. I don't think it's a given that your engine will seize though.

i was just crusing along at 100km/h came to a 70k zone, slowed down to 70, cruised through the 70k zone, got back to a 100k zone and as I accelerated (nicely, just crusing) the engine zust went NUGGA NUGGA NUGGA NUGGA NUGGA! and it got real loud by the time I had slowed to a stop, managed to drive it a couple hundred metres back to a petrol station I had just past, it was still idling but sounded horrible, turned it off. the end

mine went while turning right at lights and locked up all 4 wheels at 40 ish kms/hr 3000rpm ish. started when cold though. scary when it does it with people coming over way while you skidding sideways :-[

have just towed it back from where it has been parked up for a few weeks started it and it died started it again and it idles but still has the knocking. what would of caused the cutting out/surging before it started making the knocking noise

knock sensor telling ecu to change timing etc probably

so what are my options what would i be looking at to get it fixed is it worth it?

when the big end went in the Legacy,I had no engine light,nor did it die, was under full boost (passing) had a wee miss,then made a horrible noise

1. rebuild, around 3k for a quick build using factory parts but all new bearings, seals, second hand crank etc etc

2. forged rebuild, the sky is the limit on pricing here

3. drop a second hand engine in, anywhere between $500-$2000 depending where you look and if you can do the work yourself

It all depends what you want to do with the car, if you want to maybe keep it and continue to use as a daily driver without modding it to much etc I would go with option 1, if you want to build it tough and do a few mods etc for decent power then go for option 2, and if you just want to get rid of it then go for option 3 chuck a second hand engine in and flick it off

Interesting replies...So i guess big end goes on all sorts of different scenarios. Neway..i betta stop stealing this thread
