It does sound like water seal failure from your description

Im pretty sure mine have gone too! Started fine this morning on both rotors but when i removed the filler cap the level slowly rose and overflowed out. There were tiny bubbles and the floor behind the exhaust tip had what looked like water spalshes on it. I thought the water system worked under pressure, so wouldnt the water come out the filler cap on a healthy engine anyway?? If it is the water seals i am thankfull it has gone now and not halfway through the nurburgring.

Just to list what happened to mine when the water seal went:
Low coolant buzzer
Constant need to top up water
Loss of water from expansion tank ( combustion pressure getting into the waterways, pushes it out through the overflow, not water pressure)
Tiny bubbles in the water fill tube take the cap off you can see the bubbles clearly, when engine running.

just found this from atkins rotary. Complete rebuild kit, Gaskit set, viton oil rings etc Â£670 delivered +import charges http://www.atkinsrotary.com/store/customer/home.php?cat=537

Anyone else used this kit??

mm that looks good. I am pretty sure I need housings, too, though. It got a bit warm, gauge went up to about 3/4.

Mind you, even if I add Â£500 odd for housings, its still a good price.

Anyone know what a side housing costs?

Hmmm.

I have a similar problem... but could be completely different.

What do you guys think. I too have to top up coolant every 2 days. All started after fitting aftermarket AST.

If fitting an aftermarket AST and cap... if the cap doesn\'t seal correctly as described... what are the problems or effects with running your car like that?

Any permanent ones? Or effects only appear whilst the cap isn\'t sealing correctly - and all cured when fitting another cap that does seal?

I will be trying another cap tonight. A D1 spec one.

The two so far have been the standard Pettit Racing one which came with the Pettit Racing AST and the Pettit Racing uprated 22-24lb cap.
