I only brought the car around a month ago. To get the car home involved taking it on a 5 hour journey on the open road.
The previous owner (mechanic) had just fitted a new radiator and had been instructed that coolant should not be added until around 20 hours of driving, hence no coolant in the radiator. Car travelled completely fine for 90% of the journey but for around the last 20mins it started to get quite hot, about 3/4 of the way up the temp gauge. The temp never rose any higher than this. Anyway, it got home.
Next day I checked the radiator and there was very minimal water left. I thought the radiator may have lost this water out the over flow as there was no bottle fitted. After taking the car on a few short trips to town I found it used the water quite quickly. No water or oil leaks out of the car onto the ground. Anyway, I took the car to a local classic car mechanic to get him to give the engine a basic check over. The result of this was the mechanic thought that the car had a blown head gasket. His theory was that water was getting into a cylinder and stopping it from firing when cold but once warmed up, the water burned off and the car runs smoothly on all cylinders. I took the car away and started doing my own tests. Compression test showed cylinders 1,2,3,5 and 6 all showing bang on 150psi. Cylinder 4 showed 125psi. The spark plug that was in this cylinder was noticably cleaner than the other 5. Oil under cap is slightly milky. These all pointed to a head gasket. I have removed the head and the gasket is fine, no breaks (unfortunately!).
I am after any advice on what I should do next other than take the head to be pressure tested which I will do in the next few days.
Sorry for the extremely long winded message, I just thought i'd tell the story exactly as it has panned out so far.
Thanks once again
