UncleHo,

Thanks heaps for the advice.
I had to suspend works as my spanners are not matching well with the bolts. Time to find some better tools.

I am expecting workshop manual soon, so waiting seems to be great idea.

Oil does seem very milky, so am assuming head gasket is buggered badly.

Have drained cooling fluid, will drain oil tomorrow.

Thanks again for help.

cheers

Andrew
