How bad is this? Mayo in Oil cap and on Dip Stick, water leaking from radiator and also at back of engine, can't see where from

 

Engine is 8 valve 1.4

 

Fabia 2000

Engine overheated last night and regularly having to top up coolant!

Mayo on the dipstick = head gasket failure.

 

Stop driving it or the engine will die completely, mayo will not float the crank!

Could need the liner shims doing too, the last 5 of these motors I have done needed the liners lifting. It is a poor design compared to the 1.3 it's based on and can cost more than the car is worth to sort properly
