Vts using a lot of water
 

Hi have had my track vts a while now and recently it's using a lot of coolant I'm 90% sure it's not leaking but only really lasts about half a day before the temp light goes straight to red then I have to stop and add water them will last another 6hrs, what's the chances of it being headgaskrt?

If it's using coolant, it's not leaking from the engine, rad, hoses, heater matrix or in the oil, then it has to be burning it off.

Check for leaks. If it's using that much coolant and leaking it'll stink of hot coolant somewhere. Is there any sign of water / oil mix?

Steam from the exhaust?

If it's using that much coolant and it's not dripping (read: pouring) out the bottom of the car then the only other place it can go is in the bores. It's a headgasket failure.

Another rather extreme scenario is it's leaking into the oil via the oil heat exchanger. Another possibility but by and large it'll be the head gasket

Good shout that - forgot about the heat exchanger. Check the dipstick level. If you're rocking 15+ litres of "oil" there's the problem :(

The oil level is fine my whole block looks a bit grubby/oily and noticed like the tiniest bubbly appearing on the block just above the manifold on the right hand side

it's easy to find leaks, you always have cristal deposits around it, same colour as your coolant either blue or red.


If it mixes with the oil then you'll more than likely get some mayonnaise on your oil intake cap. As above, smells like a headgasket.

Thanks what's the chances of the head needing skimming?

Get a straight edge on it and find out :y:

Will it be that obvious to see with a straight edge?

That method, if you don't have feeler gauges you can use a torch and look for light leak.
