Good Oil

Discovery, good oil ! Despite running a very expensive kettle at the moment the new oil is running extremely well and keeping pressure ! The wonder oil in question is Valvoline racing VR1 20w50.
Even with the temperature reaching 100 plus on the guage the oil keeps at between 4 bar at start up (60 psi old money) and a regular 2.5 bar at boiling temp on rad.

As for the kettle, I am rapidly coming to the conclusion it is at least one head gasket as their seems to be some form of vapour coming from the rad and expansion caps shortly after starting. No smoke on the exhausts so think its going into the coolant. Bugger !

Nice to see you all on Saturday.

Your pressure caps are ok aren't they? I've just been through a saga on my engine which was boiling and looked like the head gasket gone. Turned out to be a combination of the temp gauge sensor reading low, fan connector now faulty (was ok before the rebuild) and the pressure cap not sealing properly.

Just looking at this evening. I think I may get some new one's as the old ones have taken a load of grief and leak at cold ! Will be oh so much cheaper.
