Fired up the HDi today after completing some work finally, new cambelt, tensioners, SKF kit
Waterpump, FAL brand
Other work is unrelated to the noise, clutch FMIC etc...
There is a bit of a high pitched squeak that comes and goes under revs? Coming from cambelt end so had me a bit worried, but engine seems to run fine.
Had a small waterleak but have fixed that, otherwise the cambelt change was ok, had the engine out to do it so made that part easy.
Quick opinion is it is either too tight, possible it's the first one I've ever done, but tensioned it to be as close as possible to the one that came off.
Or, waterpump bearing? Although new could be crap?
Another tensioner?
Belt rubbing on housing? Don't think it is this.

If it is the belt too tight, it is brand new, will it stretch/bed in slightly to get over this noise? Or best to do it all again?
Sounds more like a rough bearing than a tight belt to me tbh.
Belt is most likely to tight....Slacken the belt a tad and try again, they dont need to be all that tight like that (within reason obviously)...
Make a video showing trying to twist the belt in your fingers...
Belt is defo too tight, these are really easy to over tension! Peugeot even developed a special belt deflection tool for them they are so senstive. Your one sounds way too tight
ahhhhhhhhh nuts
Will try and get the covers off tomorrow and get a vid of it.
Any long term damage if I put a few miles on it like this? sub 25, or is that a definite no no?
Is there a quick way to get back to the tensioner? Or is it starter off, engine pinned, aux belt off, crank pulley off, all covers off again?
Shouldnt have damaged anything, if your careful you should be able to just remove cover, hold tensioner with square, loosennut, slightly loosen the belt and re torque...
If you have any doubt something moved, then put bolt back in cam / allen in crank. No need to remove the starter, just push allen in in from underneath, its quite easy
Just top cover? It's late, can't think! I'll get on it tomorrow
As others have said, belt is too tight. A general rule of thumb is you can twist the belt 90 degrees on its longest run but this is obviously not a 100% accurate way of doing it. They really dont have to be hugely tight.
Looks like I'm wrong then.
There is a bearing noise there though, or is that being caused by the belt tension?

Almost guaranteed being caused by belt tension.

school boy error.....
Ive done the same when i rebuilt my GTI6
basicly had to re do the cambelt from the refit/tension stage
FIXED!

Cheers guys, top cover off, slipped a wrench in and got the tensioner to loosen a 12th of a turn, so the locking key went from being aligned at 5 o'clock to 6 o'clock.
Did the twist test, and couldn't quite get it to 90° before, can do it now with a little bit of ease.
Not too hard to squeeze in with the covers off, and nothing else needed disturbing.
Just a water leak to fix and project is done for now!
It's from the new rear water housing I bought, bolts are all tight, but it leaks, think the o-ring must be naff, or it needed a layer of instant gasket to go with it.
