So i'm driving along the motorway at 80 yesterday when I noticed that the heater was not giving me any hot air, I looked at the temp gauge and all was normal. Then about 20 mins later the gauge began to slowly rise to 2/3rds then when I eased back to 70 it dropped to normal. I sped back up thinking that It was an air lock, (this happened once before 6 months previous when I was sitting with the engine at tick over, I turned the engine off & let it cool & it was fine 30 mins later) next thing I know the needle's in the red and there's steam pouring from the exhaust and engine bay. Oh Joy.
I have coolant pissing from the front middle/lower left side of the block pouring directly onto the powersteering tubes/rack (when I rev the engine the flow increases slightly) Also my head gasket has taken a caining and is ejecting a high-pressure jet of smoke from the middle top right side of the block.
I suspected that the worse had happened and that the engine would be totalled...if only i'd seen it 60 secs earlier!
Question being....the smoke from the exhaust was pure white, so that's just water (yes?!) so hopefully no piston ring damage. After the car cooled I put 1/2 litre of water in (that's all it had lost) and it drove normally
...albeit for 5 miles until the temp started to rise again.....
do you reckon this is a waterpump failure or a timing case profile gasket issue? It's already cost me £200 to get it home and i only replaced the manifold + tyres last week when it was MOT'd!
At the moment she still drives (not that I will drive 'till it's sorted) do you reckon a tub of K-seal and a new water pump would do the trick?
I hope someone can point me in the right direction. Cheers guys
