Endoman said:If the oil level was correct with the dipstick and there was no reading in the cabin then your float is not registering correctly. They are notoriously unreliable.
There is a breather valve at the top of the oil tank if this has failed and oil level is high (overfilled) crankcase pressure will blow it out of the filler tube.
If oil gets in the crankcase/tank breather pipe again though over filling you will get an air lock which will release though the filler as the tank vent can't cope.
I run 1/2 dipsick height and the guage never registers.
Thanks
I guess it must be this as the dipstick shows full.
When it gets this blowback pressure, where is the oil spraying out from?
The breather pipe or the filler tube? The cap on the filler tube looks pretty well sealed to me and I have no idea where the breather valve is but I guess under the wheel arch where the oil tank is?
Looks like another cleaning job for me and a more diligent regime to making sure there is the right oil level in the car.
