Whining From Cambelt Area - Help With Diagnosis?

[Tom Fenton 1,542]

Good news is that the bolt in into an end cover and not the block, with the belt off the end cover can be removed easily enough.

Much easier to drill it accurately off the car, you can try and extract the bust bolt, or otherwise drill and helicoil it.

That's good news, I take it the bolts to remove the cover are easy enough to access? I'll have a look tonight anyway.

yes, half of them are visible in your last picture, there are two dowels, also sump bolts from underneath.

Well it looks like I need a thread repair. M7 repair kits seem to cost about £30, seems pricey considering I only envisage I'd use it once, anyone fancy lending me one?

 

Obviously I now need a new bolt as well, servicebox has them at 7x100 19,5, but they are now NFP. Had a look on ebay and noticed these: http://www.ebay.co.uk/itm/260878033555?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

 

Thoughts?

Its a bolt holding a plastic cover on nothing spectacular just go to any hardware store and get some and chop it down to size saves having to wait for royal snail

I'd either drill 6.8 and tap M8, or helicoil down to M6.

Bump - so in the end I ran the car for a while without the lower cover and the whining got worse. Decided to buy a new SKF belt and pump and swap them over, they're only £40 at the end of the day. Is it worth tensioning the new belt when it's warm to avoid it being over-tensioned/tight?

 

Haynes says tension whilst cold (after a warm-up) but I did that last time and the tensioner only lasted about 1500 miles/18 months.....

[Slo 283 1 Cars]

tension it cold, you must of tensioned it too tight last time or it was a crap tensioner or just worn out

[d7ve_b 44 1 Cars]

I think it was a crap tensioner, I can't see how you can tension it too tight when the spring provides the level of tension?

[d7ve_b 44 1 Cars]

Right, getting a bit pi55ed off now. Fitted the new SKF items and followed the haynes book of lies again. At first it was fine when warm, now I've put about 100 miles on it, when the car gets warm it's whining again

 

It's definitely not the Aux belt, as I've loosened it until it whines and the tensioner area whining is still present.

 

The only thing I can think of is to change the spring (I haven't so far as none of the new kits have come with them).

 

Why is it eating tensioners?

[Slo 283 1 Cars]

must be rubbing on the cambelt cover?

[d7ve_b 44 1 Cars]

must be rubbing on the cambelt cover?

 

I suppose it could be but the noise sounds louder than rubber on plastic?

 

Other culprits I can think of are:

 

- Water pump, but it has no play and doesn't make any noise when turned by hand

- The spring, maybe worth trying another, I'll pop a wanted add up

 

Cheers,

Dave.

Hard to know without seeing it. How tight is the belt? Can you twist it by hand 90 degrees on the longest belt run? Even though its a spring loaded tensioner with a bit of careful levering you can effectively set the tension as tight or loose as you desire.

[d7ve_b 44 1 Cars]

I haven't tried twisting the belt in situ. When I've finished the 206 I'll have another look.

 

At this rate Tom, you might get to see and hear it in person
