Engine Noise

[BstewyR33]

Been a long time since I've had to ask for any assistance from this forum but was hoping someone might be able to give me what they think the noise in the video could be.

Basically I've done a timing belt change, new tensioner & idler pulley & new water pump (gates brand). I don't think I over tensioned anything - the TB was tight to get on but figured that would be the case for a new TB. All timing marks lined up as per the instructions in the service manual & old mates tutorial on how to do it. With my head down near the cams the sound definetly sounds like it's coming from under the cam cover - or could be from the front of the car somewhere (possible alternator bearing?)

Any help on the topic is greatly appreciated.

Cheers!

We've all been there.

Belt's way too tight, time to get the tools out again.

Ahh bugga! So that's the Tb too tight then...

Thanks for the reply mate - should be less a painful process second time around I guess

Just as an update - I left the TB as it was tension wise to investigate the whining noise being something else.

After doing the old metal pole onto the alternator, water pump, power steering pump, ac compressor and listening for any sort of noise - I couldn't find anything abnormal from any of those.

Searched for any information on bearings that run off those belts and came to the conclusion it was the AC tension pulley. The main reason coming to this conclusion was that the noise didn't get loader on turning the steering wheel - cancelling the PS pump. It was any loader on start up or general running - cancelling out alternator and TB, it didn't get any louder when turning on and off the AC - cancelling out the compressor. The only bearing left was the tension pulley.

Pulled it off - could hear that was rolling ruff ( when you hear what a new bearing sounds like - you know the sound it shouldn't make)

I swapped this bearing out and no more whining sound, which I'm cheering about!

The bearing itself was $7 from bursons (6301)

The video is after everything the new bearing has been fitted to the pulley - no whining noise

^{good work mate. And good on you for concluding your thread}

There's a win.

It would have been worth dropping each belt off and testing for noises before pulling the balancer either way.

Good result and cheap.

Cheers lads, yea a cheap fix & cheap win for sure.

Got quoted for a Genuine compressor from Japan - $2000ish

A company on the Southwest of Brisbane had O/E for $695 or aftermarket for $595

A shop wanted to charge around $1400 to degas, rebuild, fit & regas.

Was that shop in brisbane quoting for a replacement comp that was genuine or just one of the well known brands? I think mine might die soon so keen to see what options i have comp wise. Ive quoted oem ones at the same price from Japan. Bit rediculous lol

[BstewyR33]

Here's the message he replied to me with

I know generally speaking OE means original equipment but I think in this case it may be original equivalent

A/C compressors are much of a muchness. They do the same job, I certainly wouldnt go out of my way to source a Nissan compressor when an equivelant replacement can be had for 1/3rd of the price

Thanks for posting that, hopefully I wont need it but will be a good reference if I ever do
