Changed the stat and cam covers as planned. Took a lot longer than expected, but hey .......
Finally started her up tonight, and it started first time -- result 

But it sounds like a tractor. Not a diesel, a tractor. In fact a tractor chewing a bag of spanners 

Everything is connected etc, and I didn't really do anything that should affect it in this way, I don't think.
But, I have a sinking feeling that I have lost a washer which I was using to bridge the gap for the new stat. At first I thought I had miscounted, but now ...... 
Standing at the front of the car, it could only have gone down the gap at the front of the stat, in towards the back of the cambelt cover. It did not get down the inlets.

So, what's next? Anyone any ideas re the noise which is not related to a suspected 'foreign body'?
And if the washer did slip through, where would / could it go from there?

Thank you ................... going for a cry now and to hang my head in shame. Please be gentle

All you did was stat and cam covers?  and it was sounded fine before you did the job?

sh*t like this happens mate, dont beat yaself up 

as for fixing it i'm presuming it sounds like a metallic rattle as the washer is knocked round the block by the water pump?

Yeah me too, but couldn't work out if it could make it's way in there 
Why couldn't that gap just be dead space .....?

Murphy's Law mate. I suffer from it too unfortunately 

By the sounds of it your best bet would be to access the block through the waterpump with a torch and long magnet i would have thought,

however id wait for one of the wizards to confirm on here thats the best course of action

Cheers Webby 
Cambelt needs done as well, but had hoped to leave it for a while (finances). Guess I may need to get the lot done now if I have to take the pump off anyway 
Really don't fancy doing it myself now after all this.

I did mine recently and a bit of the stat leg snapped off when I was wiggling it off the transfer pipe. The bit must have gone straight down the waterway but I didn't know at that point. I started the car and it jingled briefly and then went quiet as normal. It's obviously jammed in there somewhere.  I'm going to hunt for it when I do the cambelt and water pump in the next couple of weeks. Fingers crossed until then. 

[jonny2112]

Are there any other options do you think? Just not sure it could have got in behind the water pump.

no probs mate... as said though i'd still wait for one of the wizards to confirm thats the case before you attempt it 

to be fair mate you didnt exactly mess it up! anyone can drop a nut, bolt or washer.... i only did it last week when doing my breathers but luckily for me it went straight through everything and ended up on the floor

Sounds like your only real option is to remove the waterpump as suggested and have a good look with a torch.

Have you gone back to basics first? Plenum fully seated ok? If one of the O rings has moved and the plenum is not sat right it will run really crap.

I'd start with that first, make sure everything is fully seated ok. Then move onto other things

completely agree.... check all of your work, make sure everything is spot on and then when every avenue has been gone down look at condemning the washer in the block.

Thanks guys, will do. Why does work get in the way of things you really need to do?
