Knocking Noise. Help Needed!

[Bowden94]

Hi guys, first post on here.

Bought this beauty a month and a half ago (See below). Slowly things are going wrong.

- Warped front discs.

- Squeek from front left wheel. (Wheel bearing???)

- Squeek from the front when over various bumps on the road. (Co-worker said springs or shocks would be on the way???)

And now finally when accelerating out on a bend and got to around 3,000rpm and a knocking started. So pulled over, switched it off. Waiting 5-10 minutes started it up and it was still there so I decided to get it towed home to be safe.

$160 later the towie dropped it off half way up my long ass driveway and wasn't able to be pushed up the rest of the way so I reversed it the rest of the way. The knocking was there at idle but once it started to gain a little bit of speed while reversing it into the garage it stopped. Once back in park (Yes an automatic, don't hate) it started again. But I switched it off straight away. Locked her up and said good night.

Now the time has come to do something about it. I am an apprentice mech. But the fella's at work aren't giving my much help as they know nothing about imports.

So here I am. Has this happened to anyone here? Does anyone know what it could be?

P.s. A co-worker at my other job and old owner of my rig said it may be a coil pack and the knocking is because it's running on 5 cylinders.

Cheers, Nick.

Need to clarify if it's a knock or a miss man! If you don't know yourself then record the sound and upload it so the guys have a chance to help...

Is the car shaking/missing? If that's the case it should be a simple fix hopefully...

[Bowden94]

Will record it asap. Dno if it helps but in the past the car was misfiring on odd occasion when revved past 4,500rpm.

[34GeeTeeTee]

What was fixed to prevent it?

[Bowden94]

Was told about it before I bought it. Apparently a retune was needed. But I haven't had the time or money to pay for it.

[34GeeTeeTee]

Nope, if it's got a missfire it's probably coilpack or plug related.... My 34 did it (I think most do eventually), IF it is a missfire you have you can grab a set of coilpacks and plugs and be good to go.... You SHOULD be ok....

If your not confident and don't have anyone thy can help you diagnose just record it and post it to be sure I am not leading you astray

[Bowden94]

Haha well I've got a 13 hour day tomorrow so I'll definitely post a video after work tomorrow.

Currently it's got quality NGK plugs and Splitfires. Would hate to think it's a coil pack.

Does the noise increase with rev speed? Does it do it in gear aswell as in park.

Have u checked oil?

[R.3.2.G.T.R]

Splitfires are coil packs, running on 5 cyl shouldnt sound like knocking noise.. more like wrx

Judging from what you said, the sound occured as you turned a corner, that if our oil was low or you were thrashing it, your car has been starved of oil and it will be time to pull the engine out.

[Bowden94]

I filmed the car on but the file is apparently to big (16 point something MB).

DVS JEZ: It originally did it in drive, not keen on trying again in case it f@!?s it more that it already is.

Hadukeno: I was boosting it round the area with a couple of mates, nothing too crazy.

Just checked the oil, was just slightly low, nothing that seemed out of the ordinary for.

[Bowden94]

BWRGTR: Yeah I know they are. Didn't realise it would be that different on 5 cylinders.

Thoughts guys? Possible piston slap maybe?

[Bowden94]

That's the noise fella's: http://www.youtube.com/watch?v=O380rhiv0uA&feature=youtu.be

[Bowden94]

Turned out to be the trans. The torque converter had actually seized onto the shaft inside the transmission. A replacement box was put in and it went away. 700 short of a manual convert.

Cheers, Nick.

[jjman]

that noise sounds horrible.

Any idea what caused the auto trans failure?

Had the fluids ever been looked at or serviced?

km?
