Thought about timing but engine starts every try and runs perfectly and pulls well,
Would timing explain that it was boiling i stopped let cool down topped up the rad and then it ran almost back down to normal for a mile till i got home.
(Don't know a lot about the timing).
I have made every effort to clear any air in the system , i ran the engine at idle with Rad cap off and let it bleed out ,Is there another way?
There is no sign of antifreeze in the oil no steam from the exhaust....... Talk about Jeopardy I'm inclined to go with the final answer water jacket blocked, What's the fix for that
Thanks Guy's Open to all ideas here
