Are you sure its the balance shaft and not one of the pulleys, or the alternator,belt tensioner or water pump,They can sound very similar when their bearings get worn/dry.Even the harmonic balancer can make some noises that sound like they are coming from the engine when it gets worn out.You can remove the belt and start the engine (for just a minute or two)to see if the noise goes away.If it does,then it will be one of the things I mentioned above.
im 90% sure its the balance shaft, noise is coming from the back of the motor, i have replaced the idler pulley and checked the other pulleys. sounds like rear balance shaft bearing. would it be alright to take the car on long trips without the motor seizing or something?
It depends on how bad the noise is,if its rattling its head off,then I wouldnt go on a long trip.But if its a slight noise then it should be ok.Do you change the oil and filter regularly.Ive seen these engines get a rattle up when the wrong oil is used,it has to be 20w/50 oil.
Yeah,something is up with it.It sounds terrible.You should just be able to hear the ticking of the injectors above the engine noise,all I hear is a rattling sound.It might very well be the balance shaft.I wouldnt be driving long distances in it.You could try an oil change and a different brand of oil.See if it makes any difference.
yeah, i don't think an oil change will do it, haha, its a shame looks like a new engine for me
Yeah,its hard to hear it properly over a video.But you can definitely hear a bad rattle.You are probably right,new engine up.Around town it might last for months,but I wouldnt be travelling any distance with it.
has anyone else had any expieriences with there balance shaft stuffing the motor? cheers.
your cheapest option is to pull the timing cover and remove the drive gear for the balance shaft. shaft stays in place but doesn't spin. may notice a slight increase in vibration at low rpm's.
otherwise you need to remove inlet manifold and replace the rear bearing which is a needle roller type bearing and can be a pain to do.
