Hey guys...
To cut a long story short, my fan belt went and I did about 5miles with it gone trying to finish off a 280 mile journey. Replaced fan belt, drove around for a few miles and it overheated again leaving mayonnaise in the sump.
After this I thought it was the head gasket.. Just been out, taken my head off ready to change the gasket.. Then the puzzlement begins:
Head gasket looks fine
Cylinder head looks fine
A few inches of water in each cylinder though :/
Also, I noticed before when changing the fan belt that a hose on the right hand side of the head (as looked at from the front of the car) was bubbling a bit, like there was a leak, and that also there was a serious amount of crystalized anti-freeze around my engine bay. Could this be anything to do with it?
Other suggestions I've had are that the head gasket might have expanded while warm and allowed water to gush in, but surely not enough to put a few inches in each cylinder?
And the last I've had is that the top of the oil filter apparently has an oil pipe, and a water pipe, and that the seperation could have corroded... But again, surely this would be a random thing and not necessarily come about through overheating?
Any input would be great...
