Coolant loss..

[donnyburger 0]

Hi people, had my Corrado VR6 for a year and a half now (ABV), and recently had an oil leak from the oil pressure sensor on the oil filter housing, which I replaced and sorted the leak. Along with this I replaced the oil temp. sensor next to it.

Since then, I have had a blank readout from the dash regarding oil temp (- ---). Which is worrying me, could it just be a break in the wire?

Along with this, it's started drinking coolant like Ollie Reed at 4am, with no visible signs of leakage.

No drips / leaks on the floor or in the engine bay,

No white smoke,

No lumpiness whilst running,

No oil / water contamination.

A few people have suggested head gasket failure, but I'd like to try to eliminate other potential issues without spendind a small fortune and stripping the engine.

Any ideas would be greatly appreciated.

check the green/black wire on the rear left sender on the oil filter housing, that's your MFA temp signal source.

The two large sensors at the front of the oil filter housing monitor for a drop in oil pressure (flashing red dash light).

Common sources of water leaks on the VR6 are:-

Water pump transfer pipe

Thermostat housing (warped)

Main water pump seal blown

Heat exchanger pipes

Sometimes the auxillary water pump can leak too.

Lift out your spark plugs. Any that have been steam cleaned by coolant will be obvious

I've got a load of coolant in the pasenger side footwell (bizarrely behind the passenger seat) that's come from somewhere, it's not water, 'cos I've tasted it. Any ideas as to how it may have got there? Could this be where it's getting to somehow?

Sounds like your heater matrix has sprung a leak and is running down the vent under the passenger seat. I'm assuming you have heater vents under the seats in a Corrado
