Afternoon one and all!

In search of my latest weird noise I have removed the cambelt, tensioner and idler.
However, my flywheel locking tool jumped while undoing the crankshaft pulley and now I need to relocate the correct hole in the flywheel.
Should the pin/drill bit go right through the flywheel or just sit in it?

Many thanks

I think you will need to wait for @Nodge68 to get home from work for this one

The timing pin definitely goes into the hole in the flywheel/ flex plate.
The position needs to be spot on, or it won't go in.
Having the locking too break isn't ideal either. The bolt does become very stuck though, even my buzz gun struggled with mine.

I've got a drill bit in the hole now. The new timing tool is due tomorrow.
Sadly, having checked the idler and tensioner, I'm no closer to discovering the source of my weird noise

Did you check the alternator overrun pulley? They are known to fail, which can make odd noises as the drive
belt oscillates.

I've already replaced everything on the aux belt system. Started with the alternator

Do you have a video of the noise?
There's very little else to make a noise if you've replaced everything.

I do, how does one get a video on here?

Load it on YouTube (you'll have to make an account), then link the YouTube video here.

That's sounding very unpleasant. Is it performing as it should? It's a bit like a big end is on the way out.

Don't say that!

It still drives fine

Can you do a video from under the bonnet? It's a very strange noise. It's definitely not a normal TD4 noise, almost race engine in sound, which makes me think there's something touching something.

I can't hear it from under the bonnet. I'm waiting a replacement flywheel locking tool. When I put it back together, I'll do another video

Ah, then it's potential something on the engine touching the body. Have a good look between the engine and body.
I had a strange vibration at certain RPMs, which I found was the fuel line that had come adrift from its clip by the PS pipes, allowing it to buzz against the floor.

It does sound like unintentional contact between something mechanical and the body.

Fcuk my life

That's rhe top of the allen hole snapped off the timing belt tensioner.

Craig_mate · Sep 28, 2023

Please tell me this is tight enough

Nodge68 · Sep 28, 2023

If it's the old belt, then it doesn't want to be tightened to a new belt setting, as it won't stretch twice without breaking. That's tighter than the new belt setting, so I'd back it off a bit. Hold the tensioner top section with an adjustable spanner.

All back together, been for a test drive, drives normally, still makes awful noise
