When you blip the throttle, short n sharp, as it picks up off idle, you hear a rattle sort of slap noise- I think it's coming from inside the cam belt cover hence I think (it's that sort of sound???) that it's my tensioner having a hissyfit. It's worrying me to the point of 'I'm going to do it this weekend!!' If it hasn't broke by then.

I was suspicious that the cambelt hadnt been done as promised so was going to do it anyway, just not quite that soon!

Do tensioners get that worn that they slap or is it likely I've got something else going on?

While I'm doing the cambelt I'll do the rocker cover gaskets as I'm there, also got some new oil ready to go in when I drop the sump to clean the pickup.

Busy weekend ahead...

More likely to be lifters.  If the tensioner was making that noise you would already have major cyl head damage.

Couple of quick oil changes and a Wynns lifter treatment?

on it. Cheers. Will do cambelt all the same though...

I could imagine it might be the cam belt tensioner bottoming out at the end of its' travel if it's come loose or started to fail. If the cam belt history is in any doubt, it's always best to change it, IMHO.

Check aux belt tensioner bearing is well greased and not partially seized - you can check this before removing cam belt cover

That's what I'd imagine it to be from how it sounds- you get a similar effect and sound turning it by hand ie. Checking after changing a belt- only with setting the tension getting forgotten... Ahem... (wistles) but...

...when I first started trying to pinpoint the sound, I thought it was coming from the o/s cam area, then decided it was more frontward. Possibly.

So anyway, I'm thinking do the wynns thing (I'm about to buy sone and read the destructions), then will dump the oil out (it's not long been changed anyway) remove the sump and clean the pickup, then do the cambelt at the weekend. That way I'll know if the lifter treatment helped hence if that was making the noise...

Will check that also  but doubt it's that...

just a point, check the waterpump pully isnt rattling around, had a bearing failure on mine the other week. took some finding as i thought it was the aux belt pully. safe than sorry check.

Another good point cheers 



This thing with the wynns, all it says is to add to the oil with it warm then run as normal- I'm assuming just until the weekend will be fine- it gives no indication as to how long it has to/ can stay in for???

Well that's the list compiled that I need to order tomorrow, consisting of;

Rocker cover gaskets and the related o-rings, gaskets etc,
Cambelt kit,
O-rings quoted for clearing the breathers,
A top up bottle for the ATF as that wants checking
Air filter.

All in all, a raping for the card I'm sure but I'm relishing the mission ahead...

The sealant I need for the rocker cover gaskets, how big is a tube? Will one tube be enough for rocker covers AND the sump; also, what specifics do I need re my ATF?? Ie. Will the old tub of comma Auto box fluid (AQM iirc) do the job?

You can eliminate all the ancillaries by removing the aux belt and running it briefly to see if the noise is still present.

Cool beans, I'll have a look later at the car when I finish work

You'll have no cooling as the water pump is driven by the aux. belt, so make it brief.
