Spent yesterday doing a change on the cambelt and my valve clearances. Everything went fine and I was happy with the tension on the cam belt, AC, PS and alternator pulleys and all timing marks were go too. I took the spark plugs out and turned the engine over anti-clockwise just be sure there was tightness and no contact between valves and pistons.

Now when the car runs it has a wining noise coming from it.

I used a gates belt with a koyo tensioner, what is the general rule of thumb for tension on the timing belt, I have herd it should allow close to 90 degree twist in the middle of the longest run?

Currently uploading 2 videos to youtube to show the sound.
 
Think so, gonna get a craic at it again this after noon. I added a bit more tension to the tensioner because with the spring on its own it didn't look properly tensioned to me
 
Never add more tension

Did you follow correct procedure of turning it backwards to get the slack out before tensioning it?

If you didn't then Google it for a guide or find someone with autodata.

Something I've noticed with gates belts in the past is that they tend to get tighter when warmed up more than some other brands of belt
 
I can remember my dad having the same problem on his accord many years ago when i was young ..after a dodgy mechanic changed the cambelt. Car sounded like a loud washing machine! He was adamant it was ok. My dad was having none of it and changed the belt himself with a new one and noise disappeared.
The belt was too tight. Go for a honda belt for piece of mind.

Yeah I turned it anti clockwise to take up the tension and make sure the timing was going to be right when the belt was taught. However it still seemed slack with the tension applied by the spring alone.

Going to re-adjust with the procedure in the Honda service manual and see
 
I have added tension to the tensioner on a bseries before.
Mine was spot on and made no whine like yours does.
Used a Honda belt though...
Worth slackening the belt off abit anyway, only need to untighten the tensioner bolt and it should re-tension itself via the spring. If no change leave the engine running on idle and use a screwdriver as a stethoscope on the tensioner bolt to see if it's that whining.
Highly likely your too tight on the belt though.
 

Re-tensioned according to the honda service manual, sounds much better. What do you guys think?
 
Thats it..Sounds better now. Check your valve clearances now and adjust them accordingly as it does sound quite tappety. Which oil you using?
 
Its very tappy, it wasn't that tappy before I done the valve clearances and changed the oil. (done the oil, filter and clearance the day before the cam belt) so it wasn't the cam belt change that caused it.

It is my first oil change since owning the car, 4k on the oil. I done the clearances to 6 intake and 7 exhaust, double checked and then again yesterday. The clearances were pretty good, just slightly on the tight side by 0.001" on some.

Wondering if changing to a different the oil has done this? I got motul 6100+ synergie 10-40w and a hamp filter.
 
I checked the lma's while I was in there aswell and none were sticky.

I am also sure i followed the the procedure for valves clearances correctly.
 
Sorted, wasn't tight enough on the feeler gauges with my valve clearances.
 
Two good lessons learnt buddy!
 
Sounds perfect good job. Was tapping its nuts off before lol Your using the correct grade of oil aswell. :)
