Well thought it best to update. Finally got everything put back on this weekend and after a bit of an issue with the battery she started. Was well chuffed. Took her for a little drive down the road and within about half a mile temp shot up and steam every where. Opened the bonnect and the hose from the radiator to the thermostat was leaking. Let it cool down and nursed it back home. Removed the oil cap to have a look and the dreaded mayo substance in the cap. Then took the cam cover off and there is more under the cover but all the cams are clean.
Question is would this be the head gasket?? I did fit a new one and new bolts but wasn't 100% that the bolts were tight enough, faulty torque wrench that was bought brand new. Also the fuel guage isnt working properly. Has a full tank of fuel but still showing empty with the light on.
