Well we did a Block test on the Blue Beast as she was pushing a bit of coolant out of the tank, infact had to test it 3 times
1st time the fuid started to turn green
2nd time we got a large air bubble and instantly the fluid turned Yellow but the coolant over flowed and went in to the tester
3rd just to be sure, this time it only went green
Did a Compression test and all looks good
Now i remember when i had mine tested for the very 1st time and that only just turn green and turned out it was the very early stages of HG failure, so we decided to pull the head.



This only the only part of the gasket that looks suspect, but i`m not convinced

Head Cleaned

Block cleaned

Just waiting for the gasket now
