'curry' smell when the heaters on? I had that when my matrix leaked....

john-saff

no real smell of heaters at all if it was the matrix would the floor carpets not be wet ?

I get this with my vrs is it possible to have an air pocket in the matrix but have no real poor effect on cooling ?

HI
Sounds like a head gasket to me
Get a sniff test done at a garage
This is a test which sucks air from your coolant expansion tank through a special liquid , If there is conbustion gasses present the fluid changes colour.
Good luck Tim

what is the noise though there is nothing like mayonaise under the oil filler cap?

Tim Wharton

HI John
The noise is conbustion gasses leaking past the head gasket into the cooling system
making bubbles in the water
You only get the mayonaise in the oil when the water is leaking into the oil
Get the snif test done
Cheers Tim
